Unable to connect to Microsoft Exchange Corporate email server

I was able to create my corporate email account and it worked fine for a couple of days. I deleted the account because it wasn't working - I wasn't receiving any new emails. Now, when I try to recreate the account, I receive the message: "The host is unknown" after I typed the name of MS Exchange server and hit next.
The Exchange server name is correct - same name I used when I firs created the account.

AV = anti-virus
1521 is listener port. Listener sets up 'server process' or thread. User then connects to server process and listener gets 'out of the way'. In many configurations the server process will set up on a completely separate port to avoid overloading and snooping of a known port.

Office 2013 - The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete.

Hi Team,
Just purchased and downloaded Office Home Premium and having trouble with Outlook. For what ever reason, I am unable to create account/add my email address ([email protected]) into the program. Through the set-up process it continuously
tells me that it is unable to connect to Microsoft Exchange, and that it must be online or connected to complete. In the end, it comes up with this pop-up listing a file. Something like that. Any pointers on how to resolve this or are a lot of people having
this problem..
Also, I installed this on my laptop (OSX 10.8.2)
and it worked fine, but not on my desktop (Win8 Pro 64-bit)
Thanks

Hello,
Does OWA work?
Does this issue occur on other users?
In Exchange 2013, most of the internal and external client becomes to use Outlook Anywhere(RPC over http).
Please make sure the autodiscover.domain.com is included in the certificate.

Exchange 2013 Issue - Cannot open default email folders. you must connect to microsoft exchange

Hello all, this is my first post and nightmare to this issue because i believe i made mistake and overlook something. I search over the internet i cant find the best answer or maybe i missed something during the configurations. The exchange was working fine
not after i change the setting following the method
Configure External and Internal URL in Exchange 2012. after that, the users outlook experiencing disconnect from exchange. I restore back the previous setting but now I cant add any new user to the any Outlook version or change the server path. it will
cause the problem which show the message below:
"Can't open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folder with your offline folders with your Outlook data file (.ost)"
I restarted the server and check all the Exchange services are running. The Outlook web is running and they able to receive and send out. The existing link to the exchange are still working so I not really sure what setting should i look into. I was thinking
about restoring back from Window Server Backup but was advise not to do it unless there are ways to look back the previous setting from the backup.
One of my ex-boss told me could be the Exchange Certificate but wasn't sure.
I really appreciate someone could advice and help me resolved this issue.

The connection to Microsoft Exchange is unavailable

Environment: Windows 7 Pro 64bit
Setup: Fresh install of Office 2010 64-bit from office 365 web site on a fresh install of Win 7 Pro 64bit.
Issue: I first launched Outlook and tried to link a new account to the client by putting in my email address and password. It seemed to take it, but a new dialog box keeps poping up asking me for my password (it shows the email address
already filled in). It acts as if it does not like my password, but I know it is correct because I can log in and get my mail through the web access.
When after 5 or 6 tries, I press cancel, I get the error message " The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action." Then I get a
dialog box listing the Microsoft Exchange Server and Mailbox.
Steps to resolve:
I am at a total loss on how to resolve this issue, is there anyway to manually connect to M.E> as it is just saying the connection is unavailable. All of the other threads dealing with this issue have been no help. I can sign into my account
at login.microsoftonline.net so I know the account is valid. I also receive email to my iPhone with the account and server. Any advice would be wonderful.
I went into Control Panel ->Mail, and deleted the profile. Then I tried to create a new profile and I got the same results as the first time through Outlook directly. Also, this is Windows 7 64 and office 64, but in Control Panel, it says
Mail(32bit). This is a completely new install so I don't know why it is not working. I have performed this exact same install on a dozen machines over the last 2 years without a single hitch.
I checked my DNS records and everything seems to check out. I haven't changed anything in DNS for over a year.
I am out of the office so I cannot copy some of the registry entries as some of the other posts recommend.
I ran remote connectivity analyzer. I don't know what it is saying, but below are the things that seemed to be irregular:
1) Attempting to test potential Autodiscover URL https://X123.com:443/Autodiscover/Autodiscover.xml
Testing of this potential Autodiscover URL failed.
2)Testing TCP port 443 on host X123.com to ensure it's listening and open.
The specified port is either blocked, not listening, or not producing the expected response.
Any help would really be appreciated.

Hi Manoj,
Can you ping your Exchange server? It would hlep us isolate the fault from network releated issue.
Is there a trusted certificate installed on Exchange 2013 server?
If you run the test of RPC over HTTP in

Hi,
This issue may occur when the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders registry key does not contain all of the required data. Specifically, these problems occur if the
AppData string value is missing from this registry key.
NOTE: The \User Shell Folders key also contains a string value called
Local AppDatawhich is different from the value called AppData. The value that causes this problem (if it is missing) is the
AppData value.
To resolve this issue, import the User Shell Folders registry key from a working Windows User Profile.
For more information, please refer:
http://support.microsoft.com/kb/2264398
Hope this helps.

I have looked in the registry and Appdata is not missing it has the following value "%USERPROFILE%\AppData\Roaming" also Local AppData is there with the following value "%USERPROFILE%\AppData\Local" i do not have a working machine to import the user shell
folders registry key so any other advice would be useful.

The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete - Cant add Outlook accounts

Hi have recently started getting the following error message when setting up new accounts with Outlook 2007:
The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
Outlook then prompts me to enter the username and password, i do so and get message again. This happens on Windows XP Professional and Vista, i cannot setup any accounts for new machines.
Points to note are that OWA works fine, and previous users who are already setup work fine also. It seems to be limited to setting up new Outlook 2007 accounts.
It can find the username fine. It comes up with green ticks underr the Online Search for your server settings:
Establish Network connection
Search for [email protected] server settings
Long on to server ---------- then it fails with a big red cross at this point
Recently i did add a second mail server to the network but it was not configured to talk to the other main mail server which was handling all the functions of mail box, CAS, hub transport. I had installed all the same roles on the second server with a view to move it across and retire the old server, the second machine is a different machine name from the main mail server. In summay my servers are:
svr001              Server 2003 R2 Enterprise x64 domain controller
mail                 Server 2003 R2 Enterprise x64 non-domain controller with exchange 2007 SP1
mail001            Windows 2008 Enterprise x64 non-domain controller with exchange 2007 SP1
The main box "mail" has been fine until i recently introduced this new server "mail001" into the network.
I am really stuck now and would really appreciate any pointers or steps to debug the above.
Many thanks,
Chris

The FIX IT here
http://support.microsoft.com/?kbid=319206 works, but only for a user who's already logged in (if you just run the fix it program and do nothing else). To make it work for all users you'll need to manually edit the registry as it says in the article.
To force Outlook to use a pre-defined global catalog server, use the following steps to set the following special registry parameter to point to the Fully Qualified Domain Name (FQDN). Doing this over-rides any setting in the MAPI profile.
Click Start, and then click Run.
In the Open box, type regedit.exe, and then click
OK.
Locate and then click the following key in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Exchange\Exchange Provider
Note You may have to create the registry path.
On the Edit menu, click Add Value, and then add the following registry value:
Value name: DS Server
Data type: REG_SZ (string)
Value data: FQDN of the global catalog server
This allowed me to roll out a bunch of laptops and not have to worry about running the Fix It for each user.
update: Sysprep seemed to remove fix. Each time a new user logged into a newly imaged laptop (on domain) same error about Outlook 2007 cannot connect to Exchange. Have tried just about everything, but all I seem to be able to do is run this stupid
Fix it each time. Luckily I don't have 1000 machines to setup because then I'd be screwed.

Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost)

Fresh installation of Exchange Server 2013 on Windows Server 2012.
Our first test account cannot access their email via Outlook but can access fine through OWA. The following message appears - "Cannot open your default e-mail folders. You must connect to Microsoft Exchange with the current profile before you can synchronize
your folders with your Outlook data file (.ost)" is displayed.
If I turn off cached Exchange mode, setting the email account to not
cache does not resolve the issue and i get a new error message - "Cannot open your default e-mail folders. The file (path\profile name).ost is not an Outlook data file (.ost). Very odd since it creates its own .ost file when you run it for the first
time.
I cleared the appdata local Outlook folder and I tested on a new laptop that has never connected to Outlook, same error message on any system.
Microsoft Exchange RPC Client Access service is running.
No warning, error or critical messages in the eventlog, it's like the healthiest server alive.
Any help would be greatly appreciated. I haven't encountered this issue with previous versions of Exchange.

So it looks like a lot of people are having this issue and seeing how Exchange 2013 is still new (relatively to the world) there isn't much data around to answer this. I've spend ALOT of time trying to figure this out.
Here is the answer. :) - No I don't know all but I'm going to try to give you the most reasonable answer to this issue, in a most logical way.
First thing I did when I was troubleshooting this issue is that I ignored Martina Miskovic's suggestion for Step4 http://technet.microsoft.com/library/jj218640(EXCHG.150)because it didn't make sense to me because I was trying to connect
Outlook not outside the LAN but actually inside. However, Martina's suggestion does fix the issue if it's applied in the correct context.
This is where the plot thickens (it's stew). She failed to mention that things like SSL (which I configure practically useless - anyone who ever worked in a business environment where the owner pretty much trusts anyone in the company, otherwise they don't
work there - very good business practice in my eyes btw, can confirm that...) are some sort of fetish with Microsoft lately. Exchange 2013 was no exception.
In exchange 2003, exchange 2007 and exchange 2010 - you could install it and then go to outlook and set it up. And when outlook manual Microsoft Exchange profile would ask you for server name, you would give it and give the name of the person who you setting
up - as long as machine is on the domain, not much more is needed. IT JUST WORKS! :) What a concept, if the person already on premises of the business - GIVE HIM ACCESS. I guess that was too logical for Microsoft. Now if you're off premises you can use things
like OutlookAnywhere - which I might add had their place under that scenario.
In Exchange 2013, the world changed. Ofcourse Microsoft doesn't feel like telling it in a plain english to people - I'm sure there is an article somewhere but I didn't find it. Exchange 2013 does not support direct configuration of Outlook like all of it's
previous versions. Did you jaw drop? Mine did when I realized it. So now when you are asked for your server name in manual outlook set up and you give it Exchange2013.yourdomain.local - it says cannot connect to it. This happens because ALL - INTERNAL AND
EXTERNAL connection are now handled via OutlookAnywhere. You can't even disable that feature and have it function the reasonable way.
So now the question still remains - how do you configure outlook. Well under server properties there is this nice section called Outlook anywhere. You have a chance to configure it's External and Internal address. This is another thing that should be logical
but it didn't work that way for me. When I configured the external address different from the internal - it didn't work. So I strongly suggest you get it working with the same internal address first and then ponder how you want to make it work for the outside
users.
Now that you have this set up you have to go to virtual directories and configure the external and internal address there - this is actually what the Step 4 that Martina was refering to has you do.
Both external and internal address are now the same and you think you can configure your outlook manually - think again. One of the most lovely features of Outlook Anywhere, and the reason why I had never used it in the past is that it requires a TRUSTED
certificate.
See so it's not that exchange 2013 requires a trusted certificate - it's that exchange 2013 lacks the feature that was there since Windows 2000 and Exchange 5.5.
So it's time for you to install an Active Direction Certificate Authority. Refer to this wonderful article for exact steps - http://careexchange.in/how-to-install-certificate-authority-on-windows-server-2012/
Now even after you do that - it won't work because you have to add the base private key certificate, which you can download now from your internal certsrv site, to Default Domain Policy (AND yes some people claim NEVER mess with the Default Domain Policy,
always make an addition one... it's up to you - I don't see direct harm if you know what you want to accomplish) see this: http://technet.microsoft.com/en-us/library/cc738131%28v=ws.10%29.aspx if you want to know exact steps.
This is the moment of ZEN! :) Do you feel the excitement? After all it is your first time. Before we get too excited lets first request and then install the certificate to actual Exchange via the gui and assign it to all the services you can (IIS, SMTP and
there is a 3rd - I forgot, but you get the idea).
Now go to your client machine where you have the outlook open, browse to your exchange server via https://exchang2013/ in IE and if you don't get any certificate errors - it's good. If you do run on hte client and the server: gpupdate /force This will refresh
the policy. Don't try to manually install the certificate from Exchange's website on the client. If you wanna do something manually to it to the base certificate from the private key but if you added it to the domain policy you shouldn't have to do it.
Basically the idea is to make sure you have CA and that CA allows you to browse to exchange and you get no cert error and you can look at the cert and see that's from a domain CA.
NOW, you can configure your outlook. EASY grasshoppa - not the manual way. WHY? Cause the automatic way will now work. :) Let it discover that exachange and populate it all - and tell you I'm happy! :)
Open Outlook - BOOM! It works... Was it as good for you as it was for me?
You may ask, why can't I just configure it by manual - you CAN. It's just a nightmare. Go ahead and open the settings of the account that got auto configed... How do you like that server name? It should read something like [email protected]
and if you go to advanced and then connection tab - you'll see Outlook Anywhere is checked as well. Look at the settings - there is the name of the server, FQDN I might add. It's there in 2 places and one has that Mtdd-something:Exchange2013.yourdomain.local.
So what is that GUID in the server name and where does it come from. It's the identity of the user's mailbox so for every user that setting will be different but you can figure it out via the console on the Exchange server itself - if you wish.
Also a note, if your SSL certs have any trouble - it will just act like outlook can't connect to the exchange server even though it just declines the connection cause the cert/cert authority is not trusted.
So in short Outlook Anywhere is EVERYWHERE! And it has barely any gui or config and you just supposed to magically know that kind of generic error messages mean what... Server names are now GUIDs of the [email protected] - THAT MAKES PERFECT
SENSE MICROSOFT! ...and you have to manage certs... and the only place where you gonna find the name of the server is inside the d*** Outlook Anywhere settings in the config tab, un it's own config button - CAN WE PUT THE CONFIG ANY FURTHER!
Frustrating beyond reason - that should be Exchange's new slogan...
Hope this will help people in the future and won't get delete because it's bad PR for Microsoft.
PS
ALSO if you want to pick a fight with me about how SSL is more secure... I don't wanna hear it - go somewhere else...

Outlook 2013 error: The connection to Microsoft Exchange is unavailable

Cannot start Outlook 2013: "name cannot be resolved" / "connection to Microsoft Exchange is unavailable" / "___.ost is not an Outlook data file (.ost)"

My work e-mail has a double-login system, where my credentials for work access are one username and my e-mail is an alias of that first username, so they differ from one another. I suspect that's why I've been having the hardest time with Outlook 2013. I
was able to add my account just fine once but changed my mind about using Outlook and removed the account. Now I can't get back into Outlook for the life of me. The error messages that show up are:
1. It asks me to verify server and Mailbox. I've tried it with both usernames (the official work username and the e-mail alias) as my Mailbox info, followed by the email domain (even tried it without the domain) and it still won't verify when I click "Check
Name".
2. This message comes up: The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.
3. Then once I click "OK" another pop-up says: Cannot start Microsoft Outlook. The file C:\Users\FirstLastname\AppData\Local\Microsoft\Outlook\FirstLastname.ost is not an Outlook data file (.ost).

Send/receive hang on "Offline address book Connecting to Microsoft Exchange" and will never finish?

When I hit send/receive on a few clients the process will hang on "Offline address book Connecting to Microsoft Exchange" and will never finish? These same user can long on the OWA and send/receive just fine. The problem is that while it's hanging it can't go out and look for new email. Any thoughts?

I had similar problem.
This actually arose due to the fact I had mistakenly set the Default web Site directory with a HTTP redirect which applied to all subfolders including OAB.
I did then rectify this by going into individual subfolders and unchecking Http Redirect from each sub folder, however unknowingly it created/modified a webconfig file under the OAB virtual directory. (you can explore it to see the
file there)
If you test your OAB url (for people with the issue), which is : http(s)://servername/oab/[code]/oab.xml you will get Error 500.
Each time Outlook 2007 was trying to connect to get OAB, it was trying to read that webconfig file.
I fixed this by changing the permissions on that webconfig file to allow everyone and the above error was done, and also my Outlook 2007 was downloading the OAB again!
Now if the above fix did not fix your problem, you can temporarily effectively disable OAB by unticking Web Distribution of OAB and Public Folder Distribution in EMC under Organisation/Mailbox/Offline Address Book. Users will be able to do a
send/reiceve without any errors/issues. However, if a new contact/user is added to your AD with exchange attributes, the clients will not be able to see this. I'm guessing if cached mode was also not used, issues would also occur if they tried using the GAL.
acidack, you are a lifesaver.
I looked at the other webconfig files in the internet directories and noticed they all had 'Authenticated Users' with read permissions while the OAB one did not. Adding this group with read permissions solved the problem; Outlook 2007
users are no longer frozen on the 'Offline address book connecting to Microsoft Exchange" message.
What caused this? I'm not sure. I was messing with the web settings trying to redirect people to OWA. Something I did must have caused this file to be re-created without the needed permissions.
Acidack and AndrewB, You are both live savers. After all these years, your solution to this problem is still spot on.

this I am trying on my test system please help me out in resolving the issue
thanks in advance,

Gary,
Open Registry Editor.
In Registry Editor, navigate to the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
Create the following value (REG_SZ): Working Directory and give it a value that points to the new database folder.
Make sure you back up the registry before you do any changes on it.

Hi dear.
We have exchange 2013 and we want auto configure outlook 2007,2010 and 2013. In first time when we are setup exchange 2013 we can auto
configure outlook. But I don’t know now we cannot configure outlook. I think when we make some change in exchange certificate ( created by exchange in first time ) and after that we cannot configure outlook. Just we can set up pop3 and imap
for outlook. Now we have outlook with pop3 and outlook web app ( OWA ) and we don’t have problem with them, but we want our client see the all contact list in outlook. When we want configure outlook with Microsoft exchange server we get the error “
the action cannot be completed. the connection to Microsoft exchange is unavailable “.please help me. I don’t know how I solve the problem.

hi.
ok. this is the out put of autodiscover url in address bar :
"" <?xml
version="1.0" encoding="utf-8" ?>
- <Autodiscover
xmlns="http://schemas.microsoft.com/exchange/autodiscover/responseschema/2006">
- <Response>
- <Error Time="10:30:23.5154338"

<ErrorCode>600</ErrorCode>
<Message>Invalid Request</Message>
<DebugData

</Error>
</Response>
</Autodiscover> ""
thanks for your help.
If it returns error code 600, your autodiscover service should be accessible in Exchange server. Please restart Microsoft Exchange Address Book service in Exchange server, then create a new Outlook profile in Outlook to have a try.
