Error message when an Exchange Server 2007 user or an Exchange Server 2010 user tries to log on to OWA
Article ID: 941146 - View products that this article applies to.
This problem can occur when the msExchVersion attribute is configured incorrectly for the user object in Active Directory Domain Services (AD DS).
Note The msExchVersion attribute may not be configured correctly if you create the user's mailbox by using Active Directory Users and Computers Microsoft Management Console (MMC) snap-in instead of using the Exchange Management Console.
If you are not familiar with Microsoft Exchange management, please contact your local systems administrator to help fix the problem.
To verify this problem, you can check the msExchVersion attribute by using the Exchange Management Shell. To do this, run the following command in the Exchange Management Shell prompt:
Get-Mailbox <User_Name>| format-list ExchangeVersion
Note Exchange Server 2007 and Exchange Server 2010 both use the msExchVersion attribute to determine the version of Exchange Server with which user objects are associated. If the version value is less than 0.1, Exchange Server 2007 or Exchange Server 2010 considers the user object as Read-only.
To resolve this problem, an Exchange administrator must run the following command in the Exchange Management Shell prompt:
Set-Mailbox <User_Name> -ApplyMandatoryPropertiesNotes
