Some users can't login to Exchange 2013 OWA

Hi,
we are experiencing issues with some of our users that are unable to login to OWA.
They receive an error message "Somthing Went Wrong..."
We are using Exchange 2013 CU2.
Outlook is connecting without issues.
We tried to move to diffrent Database, Reset User Passwords, Delegation etc...

Nothing works ;-(

I will appreciate any help,
Thanks

Could provide the whole message.  Have you tried starting Outlook in safe mode?  What client are you using to connect and what is the version of the client (i.e. Outlook 2010 SP1, etc.)?  Have look at the server for any errors in the log files?

Hi,
There is no issue with Outlook, Outlook clients are connecting to the exchange server perfectly.

Our problem is concerning logging into the mailbox using a web browser.

Thanks!

Have you checked the log files on the Exchange servers?  Problem seems to be with IIS.

I have checked the IIS logs, I found nothing suspicious.
I noticed that the http error is 500, Maybe it can provide more information.

I am able to login to the user account setting through ECP.

When I browse to the calendar settings or regional settings I receive an error :
"The configuration object data is corrupted. Field = UserConfigurationType"

OWA Error ScreenshotSure I checked, OWA is enabled.
I am attaching the error screenshot.

If i delete the mailbox and creating a new one, it works ok, but the procedure is very long - Export mailbox, Delete problematic mailbox, create new one and import the data again...

I read something That" an httpcode 500 error occurs when logging in OWA and the URL redirects to owa/auth…"

It was supposed to fixed in Exchange CU2 Maybe someone heard about this issue,

Is this a new greenfield installation, or a migration from an older version of Exchange?

If it is some users and not all, then I doubt if it is a problem with the server or browser - this looks like an issue with the user account. That is shown by the fact that recreating the account (basically a new mailbox) works correctly.

Instinct says that something didn't come across correctly, or there is a problem with the account.
Verify that permission inheritance is enabled on the user account in ADUC.
If possible, try moving the users from one database to another one.
You could also try a mailbox repair, see if that resolves things or not.

Thanks Simon,
Permissions inheritance is enabled in ADUC, and moving mailbox from one database to another did not help.

I do not think it is related to AD permissions, Since I do not completely delete the user account from AD, Just its mailbox.
When i create a new mailbox i choose existing user and then the user is able to login to webmail.
If it was an AD permissions issue, a new mailbox would not have solved the problem.

Does it make sense?

Thanks,
Alon

Simon Butler (Sembee)ConsultantCommented:
I disagree.
You are attaching a new user to the the existing mailbox. Therefore the AD object, which stores the permissions is damaged in some way. Exchange is tightly integrated in to AD.
The mailbox is just a container, if the issue was with the mailbox then a new AD account wouldn't work either.
This is an AD issue, possibly something happened on the old system and has replicated across and is now causing a problem.

I am sorry, I did not explain it well,
I am not connecting a new user account to an existing mailbox.

I am using Outlook to export the mailbox data into a PST file.
Then I choose the problematic recipient and click on Disable, Now the user has his old  AD account without mailbox.
Now i click on create a new mailbox and I choose to create a new mailbox for an existing user, check the recipient from the list of available users without a mailbox, choose the desired Datastore and now the user has a blank new mailbox which operates perfectly.

The next step is again connected to outlook and import the data from the local PST file to the new mailbox.

So this is why i think it is a mailbox related issue and not AD issue.

I did another test with an Opera browser Ver 12.6, I managed to open the mailbox through the webmail, But it was on the light version for non supported browsers...
This is the light version URL:
https://"your domain"/owa/?layout=light



Any ideas?

Solved!
After login with the light version of OWA to a problematic mailbox, I browsed to each folder Inbox, Calendar, Contacts etc..
I discovered that each time i am trying to browse the Calendar folder I am getting an error message, I assumed the Calendar folder is corrupted.

How to solve:
1. Open Outlook configured with the problematic user mailbox profile and export the calendar to a PST file for Backup.
2. Use MFCMAPI and delete the Calendar mailbox.
(Download MFCMAPI from here: http://mfcmapi.codeplex.com/releases/view/104434)
3.Open Outlook using this this command - Outlook.exe /resetfolders
4. Import the Calendar from the Backup PST.
5. Close Outlook and login to regular OWA version - The mailbox is working again :-)

Notes,
It appears that while we made the migration from Exchange 2003 to Exchange 2010 some of the mailboxes Calendars were corrupted during the move, Still Exchange 2010 OWA was able to open the mailboxes but was not able to open the Calendar folder.

Probably Exchange 2013 OWA is checking the Calendar at the logon stage and it fails since it is corrupted and returnes an error message.

Many thanks for all of you who answered and tried to solve the problem.
