Outlook 2013 stopped connecting to my Yahoo mail server

I set up my Outlook 2013 to my yahoo mail server a week or so ago when I got my new windows 8 computer. It's been working fine. I signed on today. Sent/received emails. Toward end of day, I can't sign on to yahoo mail server.
I can't send or receive emails. I did nothing to change the settings. I checked the settings, but I still can't send or receive. Why is it doing this and what can I do to fix it? The same thing is happening on my laptop. Both
were working fine earlier.

Hello,
Since you use Yahoo mail server, I recommend you contact Yahoo support to verify the issue.
Before you contact Yahoo support, please post the error when you send messages.

Outlook 2013 cannot connect to Exchange 2010 SP2 server, Outlook 2010, OWA work fine. Ideas?

After upgrading a laptop from Outlook 2010 to 2013 it can no longer connect to our Exchange 2010 SP2 environment. OWA works, Outlook 2010 works, but Outlook 2013 will not create a profile via AutoDiscover. The first two checks go, the last check
Log On To server will not.
We can take the laptop to a different network and it works fine with Outlook 2013.
What is different with Outlook 2013 where it will not connect.
Jason Meyer

Does it work when we recreate a new Outlook profile?
At this point, We high recommand that we run Microsoft Connectivity Analyzer Tool from the folloing link to check what was happening

My MacBook pro has stopped connecting to the outgoing mail server smpt (Tiscali) server, still receives mail fine, and connects to the web. Any suggestions welcome.

My MacbookPro has always worked fine, receiving and sending emails through my server,Tiscali. I took it to France for a few days, and was able to receive emails and use the web (through the wireless router and server in our accomodation), although as usual when away from home, I couldn't send emails. I tried to set up a new outgoing email route using O2 (as suggested by a web article), but it didn't work, so I deleted it, and used Tiscali webmail to send emails.
When I returned home, I selected my usual outgoing server (Tiscali), but found to my great surprise, that I could no longer send emails - Mail timed out, 'unable to connect'. I noticed when clicking on: Mail - Preferences, that in the outgoing mail smpt box, Tiscali appeared, as usual, but now was followed by (Offline)
Receiving emails and web connections have remained fine.
I've checked with Tiscali, and they can't find any problem with their server or my settings. Grateful for any suggestions about possible causes for this problem, and how to fix it.
Joe

I have just tried attaching the ethernet cable to the MacBook to see what happens. The system is fine, but when starting Mail, it never opens and locks up. You eventually just have to force quit out of the program.

Urgent!!!! Problem in sending mail through yahoo mail server

Hi
I have a yahoo account and I want to send email through yahoo mail server

But when I connect to the yahoo mail server(smtp.mail.yahoo.com) I got this error

must be pop-authenticated before you can use this smtp server, and you must use
your yahoo mail address for the Sender/From field.

Outlook 2013 IMAP connecting to Cisco Unity Voicemail

The ability to use IMAP in our Outlook 2013 stopped working back in November updates, we worked with MS Support for the other Outlook issues that were broken thinking that whatever fix would also resolve the IMAP issue. This was not the case.
Our voicemail is hosted on a Cisco Unity Server by our provider that we connect to using IMAP. Initially I was unable to connect to their server using IMAP because the November update sent their server to 100% CPU. After a Cisco patch I'm now able to
connect, however functionality is still not there.
Outlook 2010 clients seem to work fine. Outlook 2013 clients will sync the inbox the first time connecting but never after that, you are also unable to delete messages from the reading pane (able to open message and delete).
I'm aware of the root folder "Inbox" and the subscribe methods for troubleshooting this, however neither work.
Does anyone have any suggestions on where to go from here?
Thanks much

So what eventually solved this was Office SP 1.
Below is a set of packet captures with Outlook 2013 interacting with a Unity server both before and after the SP was installed.
OUTLOOK 2103 WITH SP1 – WIIN 8 shows:
Packet 223: UID FETCH 177:4294967295 (UID FLAGS RFC822.SIZE BODY.PEEK[] INTERNALDATE)
Follow TCP Stream shows CUC handles this request fine:

CUC seems to handle this ok
Packet 708: UID SEARCH UID 178:4294967295 SINCE 24-Feb-2014
Follow TCP Stream shows that CUC returns “invalid arg”. However, IMAP then performs “Fetch” request afterwards, which ultimately works

So the connectivity is work and the Outlook client now maintains functionality. The last thing I've noticed is that if you try to delete a message from either the view/reading pane or the home ribbon from Win 8/8.1 Outlook 2013/2013 SP1 it fails, you need
to go open the message to delete it.
On a Win7 machine Outlook 2013 you experienced the same thing, however after the SP1 is applied all deletion options work.
When you press the any delete key it seems the client is suppose to send an expunge command (noticed through wireshark). With the delete keys that do not function this command is not sent, those that do work the command is seen with wireshark.

Outlook 2013 not connect with Exchange server 2013 in internal network

Hello All,
I Have two Exchange server 2013 in our environment. Both server install mailbox and CAS role. After configure exchange server 2013, Outlook 2013 not connect in internal network. I have configure outlook manually. i tried by using the suggestion from blog
but not work. Outlook show that Server cannot connect/ server name could not be resolved. in outlook setting i also put exchange proxy setting. In exchange admin center i have changed the OWA, OAB, Auto discover name. But still not work.
I know that outlook can be connect from external by using ssl certificate and publish outlook anywhere but i did my configure from internal network.
Can you please suggest as soon as possible.
Thanks,
Parvez

Hi,
Firstly, I’d like to explain, same with external users, internal users use Outlook Anywhere to connect with Exchange server and use Autodiscover get all settings.
Thus, let’s try the following resolutions:
1. run the following command: get-clientaccessservice |fl autodiscoverserviceinternaluri
2. check if the host name in the above URL is in the DNS server and there is a DNS entry about the host name points to the proper IP address.
3. Check if the above host name is in your certificate.
Thanks,
Angela

Why is Mail trying to connect to an unknown mail server (and how do I stop it)?

Hi - I'm worried that someone has hacked into my system so that it tries to connect to a fake mail server (perhaps to send spam)? I usually have the activity window open when Mail is running, and noticed that it was trying to connect to an unfamiliar mail server the other day - it was shown as an IP address whereas all the mail servers in my mail accounts have names rather than IP addresses ... so I copied the IP address down and searched for it (196.201.4.6), to find that it is run by malawi.net ... in Africa. I recently upgraded to Mac OS Lion, so initially I had figured that it was showing the mail server address differently, but I couldn't think of any reason that my email servers would be in Malawi!
By now I was getting worried: I checked all my mail accounts to be sure that something had not changed, and confirmed that none of my accounts used this mail server (or mentioned the IP address); and confirmed that the "Connecting to server "196.201.4.6"" activity message only appeared when I first reconnected to the internet (i.e. now when I manually clicked on "get mail") ... which suggests to me that it is a hidden process somewhere?
I don't have a virus checker, but downloaded ClamXav and ran a check on my user folders ... but found nothing.
Any thoughts on what this might be, or - if it is something malicious or externally controlled - how I can remove it?
Thanks - andy

Hi - "display remote images in HTML messages" was already deselected, so I don't think it was an HTML message connecting.
But your response made me wonder about whether it was something else in an old email that was causing the problem - I had a search and found some emails from back in 2006 (when I did some work in Malawi for CARE) that were from the mail server (mailer.malawi.net = 196.201.4.6) that has been appearing. However, I still don't understand why (six years later) Mail is now trying to connect to this server ... I'm pretty sure that it never used to happen (and I have been a full-time Mac user since 2003), as I always have the activity window open and would have noticed, so it is only since I upgraded to Lion last week that it started. Any thoughts? I could delete/archive the old emails, but I would really like to understand what is happening?
Thanks - andy

Setting up yahoo mail server as the outgoing mail server

it should works, if you use the following parameters:

I'll bet you it will NOT work & even give you 10 to 1 odds that it will fail.
Yahoo won't relay your spam; which is why your messages will be rejected.
What is the difference between your message & a message from a spammer?

Hold off on purchasing stuff. I got my problem solved going through Apple Support for free. I'll try to walk you through this but bear in mind I've only done it once with an Apple Tech Support manager on line.
Basically you have to clear your keychain. Go to Finder Menu, Select Go, select utilities, select Keychain Access
Once you are in keychain access you may have to enter a password to unlock the keychain
Once unlocked, select preferences and then reset my keychain.
This is where I am fuzzy on what we did but as I recall that was all that was necessary with respect to the keychain access.
Save the changes
Go to the mail program, delete your existing account
Add a new account
De-select the option to automatically set up your account (VERY IMPORTANT)
Enter your email account info for @me.com
On the incoming mail server page
Enter the account type as IMAP
Enter the account description as iCloud
Enter the incoming mail server to imap.mail.me.com
on the outgoing mail server page
Enter the account description as iCloud
Enter the outgoing mail server to smtp.mail.me.com
Check use only this server
And your problems SHOULD be solved
If I were you, before messing with the Keychain stuff I'd try editing the incoming and outgoing server address in the mail program first to see if that's a shortcut.
Good luck!

Outlook 2013 cannot connect to local Exchange 2013 server

Server name EXCHANGE: is Domain controller for (domainname.local), DNS server and Exchange 2013
Has UCC CA cert successfully installed for (exchange.domainname.com)
External Outlook connections, Web Outlook and autodiscover work fine.
local DNS points autodiscover.domain.com & exchange.domainname.com to internal IP
I have used the above configuration many time for Exch2010/Outlook 2010 and it works great.
PROBLEM: Outlook 2013 clients on a local domain member autoconfigure (through autodiscover) but report a certificate error that the names do not match. When I force the acceptance for the cert error the outlook13 account setups with an exchange server
of "BIG LONG GUID"@domainname.com which cannot resolve and outlook fails.
Please help..

Hi ,
I have recently installed the exchnage 2013 as follow
one CAS and Two mail box DAG
so I was facing similier issue outlook clients were not able not see the CAS
so here are the magic solution :
1-created SRV recored for autodiscover same as acbrown2010 done
above in his reply
2-created
A record for autodiscover and the IP same as CAS IP
3-created
an internal Certificate in CAS server "create a new certificate request " and
include all names such CAS , MB's , Autodiscover this step to avoid the warning message during outlook setup because self sign certificates in ex2013 not helping
after that I have tested the outlook and was working fine NO GUID and NO certificates warning

Outlook 2013 stopped connecting to my Yahoo mail server
