What is POP3 / SMTP / IMAP / SSL / TCP-IP / HTTP / HTTPs ?

Hi Experts.
Can anybody tell me about the following questions.
What is POP3 ?
What is IMAP ?
What is SMTP ?
What is SSL encryption ?
What is TCP-IP connection ?
what is HTTP ?
What is difference in HTTP:// and HTTPs:// ?
Thanks in advance.
Regards,
-=Soniya.=-

Hi,
POP3: This is stands for Post Office Protocol this is part of mail inbox configuration, based on POP3 configuration mail will be reach to inbox from out side.
IMAP: This is stands for Internet Message Access Protocol, it is one of protocol for internet data transfer
SMTP: This is stands for Simple Mail Transport Protocol, it is outbox mail configuration, based on SMTP configuration mail will be send to target system
SSL: This is stands for Secure Socket Layer, this is mainly used to transfer data between two system in secure way. In this configuration we can provide security in transport (https) & message level (encryption & decryption)
TCP-IP: This is stands for Transmission Control Protocol-Internet Protocol, it is for using internet & intranet. This protocol will support most of all network.
HTTP: This is stands for Hyper Text Transport Protocol, this protocol convert data to XML format and send across internet & intranet.
What is difference in HTTP:// and HTTPs:// ?
HTTP & HTTPs main difference is security, http we don't have any security in message transport but HTTPs by default provide security in transport level & message level using digital certificates
I hope now clear

END OF PROGRAM 2
P.S: CHECKING !!
STEP 1.
First compile and execute the PROGRAM 1 with your USERNAME & PASSWORD. This will send a mail to your own account.
STEP 2.
Now compile both PART 1 & PART 2 of PROGRAM 2. Then, execute PART 1 - Main.java. This will retrive the mail sent in step 1. njoy! :)
In future, I hope this is added to the demo programs of the Java Mail API download package.
This is for 3 main reasons...
1. To prevent a lot of silly questions being posted on this forum [like the ones I did :(].
2. To give the first time Java Mail user with a real time working example without code modification [code has to use command line args like the demo programs - for instant results].
3. Also, this is what google has to say..
"The Gmail Team is committed to making sure you always can access your mail. That's why we're offering POP access and auto-forwarding. Both features are free for all Gmail users and we have no plans to charge for them in the future."
http://mail.google.com/support/bin/answer.py?answer=13295
I guess bshannon & Java Mail team is hearing this....
Again, Hurray and thanks for helping me make it!! cheers & no more frowned faces!!
(: (: (: (: (: GO JCODERS GO!! :) :) :) :) :)

Thanks for the reply,
I did checked by enabling session debuging and also checked pop settings it's enabled for all
mails, I tried deleting some very old messages and now the message count is changed to 310.
This may be the problem with gmail.

Problem with access to SMTP, IMAP, POP3 protocols in CAS 2013.

Hi,
we have problem with access thgrough SMTP, IMAP, POP3 protocols in CAS 2013.
If I test connection to SMTP 25 port from other computer, session end quickly.
Test from CAS2013 to localhost or public IP is OK (similar also for IMAP and POP3).
Receive connectors are with defaults settings, firewall is disabled.
Service Microsoft Frontend Transport Services restarted, but no success.
Certificate is assigned to IMAP, POP3, SMTP, IIS.
IIS and HTTP(s), protocols are OK. Clients can connects only thgrough web, mobile (ActiveSync), or with Outlook with proxy.
Do you have some tip, what to test?
If I create new testing receive connector on port 26 for anonymous, behaviour is same, quick disconnecting.
Thank's Mirek

Hi,
Pleaser try to use the following link to test your STMP/POP/IMAP e-mail, and check the test if successful:
https://testconnectivity.microsoft.com/
If unsuccessful, please check the test result, it will tell us what caused the problem.
Thanks.

What is POP, POP3, and IMAP When I Setup My Email Account in the HP ePrint App?

I have done as much research as I can do in regards to setting up the HP ePrint App Email Accounts. If you do not see your email information listed here, feel free to post it below or contact your internet service provider, phone or email company, or whomever else that might know this. I am certain there are many more that could be added but this is a rather extensive list. I hope you find what you need to finish setting up your email applications.
I have noticed information differs from website to website but as I have learned over time, with domain masking and companies buying out other companies, I just researched all the information I could find and that way if one of the hostnames or ports don’t work, then you can continue to view further into this page to see if that information is the same. At that point, if you can’t find what you need here, I would say you have done all that you can do before contacting the appropriate support team for your email information.
Most of the links are active and the ones listed below should send you directly the pages I pulled this information from but only a few of them were from the actual support sites themselves (Apple support was vague, as well as Microsoft, Macintosh, and commonly used ISPs). Save yourself some time by searching here first. I hope you find what you need in this one-stop-shop and if you get an email address not listed here please post it below and I will add it to this original document.
Lastly, as this information is from forum-based and other unofficial websites, I would like to add that this is a copy/paste/edit-for-easy-reading document I created in my spare time. This is a very long document so I do recommend using the search and find quick keys to search for the email you need but the top part of this has definitions as to what servers, ports, and hostnames are and the basic setup in case you need to know what these options are used for and what they mean.
Below are the most common settings needed to set up most POP3/IMAP Email Clients or Devices:
The following information below can be found at http://www.swestcom.com/Support/q4.htm
“What is POP3?
Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a remote server to a local email client. POP3 allows you to download email messages on your local computer and read them even when you are offline."
"What is IMAP?
The Internet Message Access Protocol (IMAP) is a mail protocol used for accessing email on a remote web server from a local client. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients and web servers."
"Main difference between IMAP and POP3:
The POP3 protocol assumes that there is only one client connected to the mailbox. In contrast, the IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your mailbox is about to be managed by multiple users."
"What is SMTP?
Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending emails across the Internet. SMTP uses TCP port 25 or 2525 and sometimes you can have problems to send your messages in case your ISP has closed port 25 (How to check if port 25 is open?). To determine the SMTP server for a given domain name, the MX (Mail eXchange) should have more information."
"When setting up:
POP - choose POP and the incoming server port will default to 110
IMAP - choose IMAP and the incoming server port will default to 143
All other settings are the same.
Username = [email protected]
Password = the password you set up when you configured your mail box
Incoming Mail Server = mail.yourdomain.com
Outgoing Mail Server= smtp.yourdomain.com
Outgoing Server Requires Authentication (typically found in advanced options or settings)
Do NOT check "Log on Using Secure Password Authentication"
Use the same Username and Password as Incoming or select "Use Same Settings as Incoming"
Outgoing Server Port= 2525 or 587This is subject to change based on the individual preferences of your ISP"
Note - Substitute your actual domain name for "yourdomain.com" and substitute the first part of your email address for "user."
Email Ports
For networks, a port means an endpoint to a logical connection. The port number identifies what type of port it is. Here are the default email ports for:
POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
Secure SMTP (SSMTP) - port 465
Secure IMAP (IMAP4-SSL) - port 585
IMAP4 over SSL (IMAPS) - port 993
Secure POP3 (SSL-POP) - port 995.

Have you ever wished you could use your AOL email account with something else, something more powerful, something more convenient than AOL, something like Outlook, Windows Mail, Outlook Express, or The Bat!? Thanks to the wonders of IMAP, you can.
If you set up your AOL email account in any email client capable of IMAP, you can receive and send messages easily. Even the AOL folders — Spam, Saved, Sent Items and your Trash will be there automatically. Of course, you can also use POP to fetch incoming mail in an uncomplicated fashion.
For instructions on how to assist you with this you can also follow this link: http://email.about.com/od/aoltips/qt/Access_an_AOL_Email_Account_with_any_POP_IMAP_Email_Program.htm
Set Up POP or IMAP E-Mail on an Android G1 How do I set up POP or IMAP E-Mail on an Android Device?
From the home screen, tap Applications > Settings > Accounts & sync > Add account > Manual setup.
On the Incoming settings screen, in the Protocol drop-down menu, select IMAP or POP3. We suggest you select IMAP because it supports more features.
In the Email address and Username text boxes, enter your full e-mail address, for example [email protected], and then select Next. Your user name is the same as your e-mail address.
In the Password text box, enter your password.
In the IMAP server or POP3 server text box, enter your IMAP or POP server name. For information about how to look up the server settings you need to complete this step and other steps in this procedure, see “How do I find the server settings” later in this topic.
In the Security type drop-down menu and Server port text boxes, specify the POP or IMAP settings that you looked up in step 5, and then tap Next. Your e-mail application will check your IMAP or POP settings.
On the Outgoing server settings screen, the Login required option should be selected for you, and the Username and Password text boxes should be filled in.
In the SMTP server text box, enter the SMTP server name you looked up in step 5.
In the Security type drop down menu and Server port text box, specify the SMTP settings that you located in step 5, and click Next.
In the Account name, text box, enter a name for your account (for example “Office 365 email” or “Work email”). In the Your name text box, enter the name you want displayed when you send e-mail to others (for example “Tony Smith”), and then select Finish Setup.
What else do I need to know?
If your e-mail account is the type that requires registration, you must register it the first time you sign in to Outlook Web App. Connecting to your e-mail account through a mobile phone will fail if you haven't registered your account through Outlook Web App. After you sign in to your account, sign out. Then try to connect using your mobile phone. For more information about how to sign in to your account using Outlook Web App, see How to Sign In to Your E-Mail Using a Web Browser. If you have trouble signing in, see FAQs: Sign-in and Password Issues or contact the person who manages your e-mail account.

The following information is according to a forum comment at the bottom of this webpage concerning HOTMAIL and mail server settings:
“As other web based email services, Hotmail is using the HTTP protocol for connecting you to your mailbox. If you want to send and receive Hotmail emails using an email client software, then your software must support Hotmail HTTP access for your email account. Some email clients, such as Outlook Express or Microsoft Outlook, offer builtin support for Hotmail accounts, so you only have to select HTTP when you are asked to select your email account type and select Hotmail as the HTTP Mail Service Provider.”
Mail Server Settings for Hotmail using the Microsoft Outlook Connector
If you are using Microsoft Outlook & the Outlook Connector, you can define your Hotmail account just like any regular POP3 email account:
Hotmail Incoming Mail Server (POP3) - pop3 . live. com  (logon using Secure Password Authentification - SPA, mail server port: 995)
Hotmail Outgoing Mail Server (SMTP) -smtp . live . com (SSL enabled, port 25)

Yahoo Mail offers standard POP3 access for receiving emails incoming through your Yahoo mailbox, by using your favorite email client software. To setup your email client for working with your Yahoo account, you need to select the POP3 protocol and use the following mail server settings:
Yahoo Incoming Mail Server (POP3) - pop.mail.yahoo.com (port 110)
Yahoo Outgoing Mail Server (SMTP) - smtp.mail.yahoo.com (port 25)
POP Yahoo! Mail Plus email server settings
Yahoo Plus Incoming Mail Server (POP3) - plus.pop.mail.yahoo.com (SSL enabled, port 995)
Yahoo Plus Outgoing Mail Server (SMTP) - plus.smtp.mail.yahoo.com (SSL enabled, port 465, use authentication)
· Google GMail Settings
The Google GMail service offers email client access for retrieving and sending emails through your Gmail account. However, for security reasons, GMail uses POP3 over an SSL connection, so make sure your email client supports encrypted SSL connections.
Google Gmail Incoming Mail Server (POP3) - pop.gmail.com (SSL enabled, port 995)
Outgoing Mail Server - use the SMTP mail server address provided by your local ISP or smtp.gmail.com (SSL enabled, port 465)
MSN Mail Settings
The MSN email service allows you to use the MSN POP3 and SMTP servers to access your MSN mailbox.
MSN Incoming Mail Server (POP3) - pop3.email.msn.com (port 110, using Secure Password Authentication - SPA)
MSN Outgoing Mail Server - smtp.email.msn.com (select "My outgoing server requires authentication")
Lycos Mail Settings
The Lycos Mail Plus service allows you to use POP3 and SMTP servers for accessing your Lycos mailbox.
Lycos Mail Incoming Mail Server (POP3) - pop.mail.lycos.com (port 110)
Outgoing Mail Server - smtp.mail.lycos.com or use your local ISP SMTP mail server
AOL Mail Settings
The AOL email service is a web based system, designed for managing your AOL mailbox via HTTP IMAP access. Unlike Hotmail, you can use any email client to access your AOL mailbox, as long as it supports the IMAP protocol.

The Netscape e-mail system is web-based, which means you can access their e-mail from any Internet connection. Netscape Internet Service also supports AOL® Communicator, Microsoft® Outlook, Microsoft® Outlook Express, and other POP3 e-mail software. The outgoing mail server needs SSL support, so make sure your email client software supports SSL connections over the SMTP protocol.
Netscape Internet Service Incoming Mail Server (POP3) - pop.3.isp.netscape.com (port 110)
Netscape Internet Service Outgoing Mail Server - smtp.isp.netscape.com (port 25, using a secure SSL connection)

Migrating exchange 2003 to 2010 while everyone is running SMTP, POP3 and IMAP on the old exchange 2003

Hi all
We have a legacy Exchange 2003 running with more than 800 users and with a very mixed configuration for client access. Most of users are running POP3/SMTP on the Exchange, some are running IMAP/SMTP and some are running MAPI access.
Please note that THERE IS NO WAY that we move all users to MAPI access before the installation (due to deadlines).
We plan to install a new Exchange 2010, starting with a CAS/HUB server. We do not need to migrate users automatically, and we can proceed later to move them individually to the new Exchange 2010 infrastructure in a non-transparent way.
More importantly, we need to maintain that everyone receives their e-mail and all communication through the exchange 2003 continues uninterrupted.
My question is can we install the new CAS/HUB server, while maintaining the old exchange server running with it's old name and create new names for the CAS/HUB server. In such a configuration, will all the Exchange 2003 services continue to run as usual
(POP3/IMAP/SMTP/MAPI)?

In addition, you may also spend some times at below mentioned helpful resources to check the prerequisites before moving all mailboxes from exchange 2003 to 2010 :
http://exchangeserverpro.com/wp-content/uploads/2011/02/Exchange-Server-2003-to-2010-Migration-Guide-V1.3-Planning-Chapter.pdf

https://www.simple-talk.com/sysadmin/exchange/upgrade-exchange-2003-to-exchange-2010/
Moreover, to avoid any interruption during the completion of migration process, you can also take a look at this application(http://www.exchangemigrationtool.com/) that could be a good alternate approach
for you.

POP3 and IMAP Won't Start - Dovecot error 89

I have been struggling with what should be a simple problem all day: turning the mail server on!
This is a clean out of the box start. I bought a new Mac Mini with Mountain Lion Server.
POP3 and IMAP services will not start and Dovecot repeatedly reports the following (no more detail anywhere that I can find):
Nov 7 16:59:24 artemiscom com.apple.launchd[1] (org.dovecot.dovecotd[1151]): Exited with code: 89
Nov 7 16:59:24 artemiscom com.apple.launchd[1] (org.dovecot.dovecotd): Throttling respawn: Will start in 10 seconds
SMTP is running and I can telnet into port 25.
serveradmin fullstatus mail gives the following:
mail:setStateVersion = 1
mail:readWriteSettingsVersion = 1
mail:connectionCount = 0
mail:servicePortsRestrictionInfo = _empty_array
mail:protocolsArray:_array_index:0:status = "ON"

mail:imapStartedTime = ""
mail:servicePortsAreRestricted = "NO"
mail:state = "RUNNING"
mail:postfixStartedTime = "2012-11-07 16:41:49 +0000"
If I restart the mail server POP3 and IMAP staus goes to STARTING and then to STOPPED.
I've managed to get Dovecot working on a Centos server but the generally simple configuration on the Mac has me dumbfounded.
Any help is appreciated whilst I still retain my sanity.
Thanks

OK. I managed to solve this problem.
When the mail server is first initialised SSL certification for dovecot is set to on but the certificates are all commented out in the configuration file.
To determine this is the problem, turn the mail server off then at the command line start the server by entering the following command:
/Applications/Server.app/Contents/ServerRoot/usr/bin/doveconf -f service=master -c /Library/Server/Mail/Config/dovecot/dovecot.conf -m master -p -e
This is the output I received:
/Applications/Server.app/Contents/ServerRoot/usr/sbin/dovecotd -F
doveconf: Fatal: Error in configuration file /Library/Server/Mail/Config/dovecot/dovecot.conf: ssl enabled, but ssl_cert not set
Edit the file /Library/Server/Mail/Config/dovecot/conf.d/10-ssl.conf:
sudo vi /Library/Server/Mail/Config/dovecot/conf.d/10-ssl.conf
You can do one of two things:
1) Edit the line #ssl = yes to:
ssl = no
2) Uncomment the ssl_cert, ssl_key and ssl_ca lines
Now restart the mail server and check the logs for dovecot error 89 (shouldn't be there) and/or at ther command line enter the command:
sudo serveradmin fullstatus mail
This will display the mail server status which should be something like this (note pop3 and imap now running):
mail:setStateVersion = 1
mail:readWriteSettingsVersion = 1
mail:connectionCount = 0
mail:servicePortsRestrictionInfo = _empty_array
mail:protocolsArray:_array_index:0:status = "ON"

Gwia abends or freezes several times a day - imap ssl

Hello,
current system - NW6.5 sp8 - 3 node cluster - GW8.0.3 hp3 - gwia running in it's own address space
Our GW install had been stable for long time running 8.0.2 hp3. Then two changes were made to support some new clients that required IMAP and SMTP in a secure way.
On Gwia, IMAP SSL was set to required and SMTP SSL was set to enabled. In gwia.cfg the /forceinboundauth was added. So now, any host sending SMTP to gwia must authenticate.
Things went OK for a while but the number of clients connecting via Imap/SMTP has increased and problems started. Gwia would freeze or abend and had to be restarted. I upgraded to gw8.0.3 hp3 which as far as I know is the latest available version. But the abends and problems continue. Here is an example of an abend -
14/06/2013 17:25:21 : SERVER-5.70-2187 [nmID=D0006]
Removed address space because of memory protection violation
Address Space: GWIA
Reason: Page Fault, Attempt to write to non-present page
Running Thread: GWIMAP-SSL-Handler_5
EIP: 0xF53125BD (LIBC.NLM + 0x945BD)
Access Location
I have been watching the gwia address space from monitor and it grows quite large. When gwia first loads the allocated space is 8MB, after a short while it grow rapidly to 50MB. I have seen it at 200MB+.
Any ideas what I can do?
Regards,
Paul

Bob,
Finally the our GW (8.0.3) is running on linux (oes11.1). That has fixed it, the gwia keeps running with exactly the same IMAP users/clients/load etc. So far it has been running for 3.5 days. I kept the 'IMAP service' going on NetWare by having a cron job that ran twice a hour, it unloaded and then reloaded the gwia. It would take ages to shut down and unload but would get there eventually. In the last few days before the migration I had to change the cron job to kick gwia three times an hour as it would not last the 30 minutes!
Regards,
Paul

Second, GW 8 on NetWare is, in my experience, not nearly as stable / robust as on Linux. We consolidated from 5 NW servers to a single ( same class ) Linux system and both increased performance and greatly improved stability. As a half step, you can easily run just the GWIA on a Linux VM to "outsource" the abends. And on Linux when an agent dies, you can rig it to auto restart so user's have no idea its happening.

Can't open IMAP SSL ports

I use IMAP SSL to connect to my mail servers, using port 993 for incoming and 465 for outgoing mail. Despite working fine for more than five years, I have suddenly been unable to connect to the mail servers now. I'm using an Airport Extreme, setup with Airport Utility v. 6.3.2, OS X v. 10.9.2. I've assigned static IP addresses to all of my computers on the network. And I've forwarded both the TCP and the UDP ports in the Airport Utlity. But testing the ports still shows them as closed. Any advice would be appreciated.

First: host.allow and hosts.deny do not stop ports being opened. They only restrict access when a client connections, and only if the application that is accepting the connection supports tcp_wrappers.
Second: to really see what ports are open, use the command:
netstat -tnlp
Third: what is your firestarter configuration? Post the output of (as root):
iptables -nvL

Can't send using SMTP with SSL on Exchange 2003

We have an exchange 2003 server. The iPhone is configured for IMAP w/SSL for incoming and works fine. When we have SSL turned on on the outgoing SMTP, we get the message "Cannot send mail. Check the account settings for the outgoing server mail.domain.com". With SSL turned off, it works fine.
I set up outlook on a PC to use IMAP/SMTP w/ SSL and it works fine. I can send and recieve with no errors.
We're sure the user name and password entered for the outgoing are correct.
What else could be causing the iPhone not to send, but where Outlook works fine?

The new phone at the Verizon store had the exact same symptoms. Ergo...the problem was in my server.
So...if anyone else has this problem (can't send file attachments)...go to Exchange Server (I'm running 2007..settings on other version are slightly different), server settings, find the send hub. Click on it then look for the Exchange Active Sync tab and click it. Check the Ignore Client Certificates. This may only apply to those who run self generated SSL certs on thier Exchange Server...cheap **bleep**. LOL
I swear...last week, before buying this Thunderbolt my OG Droid sent file attachments just fine. Somehow I inadvertantly set the Active Sync to accept client certificates. To err is human...to blame it on Verizon is more so. LOL

POP3 to IMAP Converter

I am looking for a POP3 to IMAP converter app (something comparable to "Outlook Connector"). Live Hotmail is POP3, but I want to use either macmail, Outlook, or Thunderbird, and have all subfolders transfer.
Does anyone know of a third party app?
Thanks

So what you're after is a way to access your local emails via IMAP as you can only access them right now via POP3?
In that case, assuming you have a machine that has a permanent internet connection you could look at MailServe for Snow Leopard. It can be configured to pull emails down via POP3 and then you're essentially running an email server off your machine. The program is just a GUI for pre-existing applications that OS X Server uses and are also present in the client version. Combine it with a DynDNS URL and have the machine also perform the duties of a DNS server and it's a complete system for handling all your email via IMAP.

SQL Developer wont work via SSL (TCPS)

I am trying to get SQL Developer (1.5.1) to connect to our Oracle database using SSL (tcps -- port 2484) and am getting a very generic error. (I have no error connecting to the same database over the unencrypted port -- 1521).
Status: Failue - Test failed: Io exception: The Network Adapter could not establish the connection.
I personally think that the connection is timing out, but all logging/debuggig features I can find do not prove anything either way. I have successfully connected to the database via SSL using tnsping and sqlplus. I have also successfully imported the certificate from the database server into the cacerts file in sqldeveloper/jdk/jre/lib/security This error is the same whether I use my TNSNAMES file or a custom JDBC url.
Please reply if you have questions/ideas/solutions.
Thanks, Dan

This has helped, but I am not 100% there.
After altering my setting to use OCI/Thick driver and upgrading to 11g client, (and verifying that I could sqlplus/tnsping/odbc as before) the following happens:
When testing the connection or trying to connect with tnsnames method, the dialog box comes up just telling me it's testing/connecting, and never stops trying (and therefore also never fails).
This also happens when I try to connect via a custom JDBC URL,
BUT
When I test the connection using the same JDBC URL, I 'succeed' -- so I must be close.
My Custom JDBC URL is
jdbc:oracle:oci:@(DESCRIPTION=(ADDRESS=(PROTOCOL=tcps)
(HOST=hostname.fqdn)(PORT=2484))(CONNECT_DATA=(SERVICE_NAME=test))
(SECURITY =(SSL_SERVER_CERT_DN="CN=hostname.fqdn, OU=My Unit, O=My University, L=City, ST=State, C=US")))
What might I be missing?
Thank you.

Lumia 800 - pop3 and imap

Anybody setup a POP3 account on the phone and find that it works 100% like an IMAP setting? POP3 traditionally does not synchronise backwards, i.e. you download message to phone and leave original on server, delete off phone, it stays on the server. However in their wisdom it seems that not only can you NOT switch easily between a POP3 and IMAP account setting (you need to delete the account and then reinstall it), it also has defaulted that the POP3 setting, is the EXACT same as an IMAP.
Am I missing something? Granted this is only my 5th smartphone and 50th time I have set the same account up, but yeah must definately be me, as a company like Nokia would of checked their programs before giving it out... right?
Any assistance, including proving that it is me stuffing it up, would be greatly appreciated.
Thanks in advance,
LUCH

Hi LUCHlumia800,
Thanks for your feedback and welcome to the forum.
What you describe is not really what is different between POP and IMAP. POP actually does allow for syncing back to the server and remove mail there once deleted on the client. Actually POP can (optionally) be configured to either remove from server when removed on the client or remove from server once fetched. While these options are available implementation is not compulsory.
IMAP on the other hand basically mirrors the server and client sides so whatever happens on one side also happens on the other including adding or removing folders.
Hope this helps,
Kosh

Instructions for converting from POP3 to IMAP in Outlook 2010

I have been using Outlook a POP3 Google Apps (Gmail) account for a long time. I have never used IMAP but am intrigued by the synchronization that accompanies IMAP. Since I often use my email from the Gmail web app away from my Outlook installation,
IMAP seems like the way to go. So I would like to convert my existing POP3 account to an IMAP account.
1- Can you point me to step-by-step instructions on how to do this?
2 - Will all my PST folders and email automatically sync to the Gmail servers?
3 - what problems can I expect to encounter and how do I avoid them?
Thanks for your time and advice.

No, you cannot "convert" an account from POP3 to IMAP.
You'll need to remove the current POP3 account (this will not delete any data) and then add the IMAP account. This will create an additional folder set which is required for the synching of the IMAP account (it will mimic the folder structure of the
IMAP account).
If there are messages in your local folder which are not on the IMAP server, you can move them manually to a folder in the IMAP account.
Before you start to reorganize your data, it is recommended that you start with a good backup of your Outlook data so that you can easily restore it in case something goes wrong. For instructions see;

Changing Mail Account from POP3 to IMAP

I have to change hosts for my domain and primary e-mail address, and as long as I need to recreate my account, I’d like to change it from POP3 to IMAP. How would I change the account settings in Mail so that all my previous e-mails aren’t deleted when I change protocols? Thanks.

As I don't know whether what you want to do is possible or not, I would rather create a new account with the new settings and copy the emails from the old one to the new one (I think this will keep email dates correct). Then, after verifying that the new one works OK, I would delete the old one.

Exchange 2013 POP3 and IMAP connectivity issues 0x800CCC0F

Hi all,
there's an Exchange 2013 server running without problems during "regular" use, but when it comes to POP3 and/or IMAP (we really need that for some systems), everything is fine until there's a message with an attachment of about 100kb or more.
We can poll messages with smaller attachments without problem, but bigger sizes won't work.
So for testing I tried POP3 within Outlook Express, it gives Error 0x800CCC0F
Telnet to TCP110 simply breaks up the connection when I try "retr"
IMAP shows those messages as "to be deleted", but they are accesible within OWA.
Test-PopConnectivity (also for IMAP) runs smoothly and successfully.
Firewall is opened for all connections.
Problem is and has always been there. The server is updated to the newest SP/updates.
I tried both 110/143 and corresponding SSL - no difference.
Pop3 and Imap logging shows no errors
There's Trend Micro Messaging Security installed, but has been disabled for testing - no difference. (Issue has been there before installation of TM)
So, any ideas how to fix this? I'd appreciate...
Thanks in advance,
Robert

Hello,
Take a network trace on both ends to see if there are any devices like firewalls drop the package.
