Exchange Server 2010 Out of Office


Exchange mailbox may have multiple SMTP addresses. For outgoing Out of Office messages Exchange 2010 server always uses the primary SMTP address. For example, John Doe has a mailbox with primary SMTP address and secondary SMTP address. In case an external user has sent a message to (secondary SMTP address), he get an OOF message from (primary address). This behaviour is by design in Exchange 2010 server.

MultiOOF application ensures that the OOF message's From: address will be the same as original message's To: address.

The application is a custom transport agent.

Current version:



On your Exchange 2010 Hub Transport Server or Edge server computer:

  1. Select (or create) a user account that is a member of the local Administrators and Domain Users security group.

  3. Create C:\Program Files\MultiOOF2010\ directory.

  4. Download archive file to C:\Program Files\MultiOOF2010\ directory and extract all files.

  5. Run MultiOOF2010Setup.exe. Click Install button. Make sure that MultiOOF2010 is appeared in the list of Transport agents. Click Enable button. Click Exit button to close the program.

Q. I am having trouble getting the program to work. When I enable the transport agent, I get 1052 ans 16023 errors in Event Viewer and the Transport service will not stay running.
A. Exchange uses the Network Service account for the Transport Service credentials and it seems this account didn't get security permissions to MultiOOF2010 program folder. Try to add Network Service account read permissions to that folder.
