  • Applies to:
  • Operations Automation 5.4

Symptoms

Public Folder creation on Exchange 2013 installation fails with the following error message: Could not load file or assembly Microsoft.Exchange.Data.dll
The problem occurs only in POA 5.4.x.

Cause

The Windows Provisioning Engine Pool IIS application pool on the WPE server is using .NET 2.0 instead of the required .NET 4.0.

Resolution

After installing any POA 5.4 update, the Windows Provisioning Engine Pool IIS application pool on the WPE node(s) in the AD domain with Exchange 2013 installed should be manually switched to .NET 4.0. Use IIS Manager on the WPE server(s) to do this.
