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
