I have one exchange mailbox that cannot be accessed this morning.  If I try to logon to it from OWA I get the error, A Problem occurred while you were trying to use your mailbox.  The mailbox opens in Exchange but will not send any emails nor will it receive any new ones.  I checked the logs on Exchange server I do not see anything referencing this.

I just tried moving the mailbox to see if that would fix the issue.  I get the below error trying move.

Summary: 1 item(s). 0 succeeded, 1 failed.

When an item can't be read from the source database or it can't be written to the destination database, it will be considered corrupted. By specifying a non-zero BadItemLimit, you are requesting that Exchange not copy such items to the destination mailbox. At move completion, these corrupted items won't be available in the destination mailbox.

Exchange Management Shell command attempted:
'Consoto.com/PD Users/IS/Test User' | New-MoveRequest -TargetDatabase 'Mailbox Database 0482295700' -BadItemLimit '20'

If it is not related to the authentication (username and password seem to be ok, and account is not locked), then:
* Maybe the database is corrupt. Do you have several databases? Could you move that mailbox to another database, just to check?
* This issue can occur because the Exchange 2010 Store limits the number of non-MAPI sessions that other services generate, such as IMAP, POP, Outlook Web Access, Microsoft Exchange ActiveSync (EAS), or Exchange Web Services (EWS). By default, sessions per user are limited to 32, and service sessions per user are limited to 16. Such values are quite high bit, can you think it could be the reason?
* To get diagnostic information, you can run the Exchange connectivity test using that mailbox credentials: https://testconnectivity.microsoft.com/ -> you can perform several tests; at least run EWS and Outlook test.

Is that mailbox migrated from another mail server?
Are you using the credentials of the user who own the mailbox? Or administrative or delegated credentials?

Thanks Tahir - I'm not moving the mailbox from 2007 to 2010.  It's been functioning on 2010 for several years now.  I tried to move it to a different database today  and that's when I got that error.  

Carlos - I tried increasing the store limits and it did not help.  I tried the connectivity tests but they did not find any issues with the mailbox.  

I am using the credentials of the user of the mailbox.  I verified the credentials are still valid.

Have you tried restoring the mailbox from a backup prior to the day you had the problem with it?

Before going to a restore, try a Mailbox Repair.
That uses the command new-mailboxrepairrequest
