Im having a really strange problem. Im running Exchange 2007. A few users have reported getting an error accessing OWA. The message states that the mailbox could not be found. I open the Exchange console and sure enough, the mailbox is no longer there. The really strange part is that the user is still able to send and receive mail using Outlook. This has happened to 4 users now. Has anyone else seen this before? Im completely baffled by this. Any help would greatly be appreciated. Thank you!

If you open the shell and do get-mailbox username or get-mailboxstatistics username does it show anything?James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Hi James, I ran both commands for the user missing his mailbox and this is what I got: Get-Mailbox CategoryInfo : InvalidData: (:) [Get-Mailbox], ManagementObjectNotFoundException FullyQualifiedErrorId : C1BB80CD,Microsoft.Exchange.Management.RecipientTasks.GetMailbox Get-MailboxStatistics CategoryInfo : NotSpecified: (0:Int32) [Get-MailboxStatistics], ManagementObjectNotFoundException FullyQualifiedErrorId : C99C2884,Microsoft.Exchange.Management.MapiTasks.GetMailboxStatistics

Possibly your database is corrupt, I would plan on creating a new DB and moving on all your mailboxes to the new DB.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

I'm running my mailbox servers in a CCR configuration. Should I reseed the database from the other node or am I better creating a new database and moving mailboxes as you suggested?

In a possible corruption scenario, it's best to create a new DB. You don't know the integrity of the DB from the other node. James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com

Thank you James! I will follow your suggestion.

Is the legacyExchangeDN property still present? proxyAddresses? msExchMailboxGuid? msExchMailboxSecurityDescriptor? msExchHomeServerName? showInAddressBook? --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Hi Rich, Yes. The attributes are present and populated. Everything looks ok.

And when you use "get-mailboxstatistics" and use that user's mailbox GUID does it find the mailbox? I'd begin to suspect that you may not have the necessary permission to access the information if that fails. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

I opened a case with Microsoft support. They were unable to come up with a cause for this. They recommended creating a new database and moving mailboxes over. Thanks everyone for you help!
