user was unable to access his OWA

User was able to access his outlook. But can’t access OWA.

Symptoms:

When users try to log on to Microsoft Office Outlook Web Access in Exchange Server 2007, they receive the following error message:” A problem occurred while trying to use your mailbox. Please contact technical support for your organization

 

Cause:

 

This issue occurs when the msExchVersion attribute is not set correctly on the user object in the Active Directory.

 Exchange 2007 uses the msExchVersion attribute to determine the version of Exchange that user objects are associated with. If the version value is less than 0.1, Exchange 2007 considers the object “read-only” and cannot write changes to the object.

 Note the msExchVersion attribute may not set correctly if you created the user’s mailbox by using the Active Directory Users and Computers Microsoft Management Console (MMC) snap-in instead of by using the Exchange 2007 Management Console.

 Resolution:

 

 To resolve this issue, type the following command at the Exchange Management Shell prompt:

Set-Mailbox User_Name -ApplyMandatoryProperties

 

To verify the msExchVersion attribute, type the following command at the Exchange Management Shell prompt:

Get-Mailbox User_Name | format-list ExchangeVersion

 

Thanks
