Symptoms

After upgrade to 5.5.1, modifying Exchange mailboxes, like changing limits, fails on domains with Exchange 2010 Multi-Tenant with the error below:

Cannot load Windows PowerShell snap-in Microsoft.Exchange.Management.PowerShell.E2010 because of the following error: The type initializer for 'Microsoft.Exchange.Data.Directory.Globals' threw an exception.

Cause

.NET 4.5 installed on WPE nodes is not compatible with 5.5.1 update on domains with Exchange 2010 Multi-Tenant.

Resolution

Uninstall .NET 4.5 on all WPE nodes, use .NET 4.0 instead.
