Exchange Server 2013 SP1 Transport Service issues with CodeTwo Exchange Rules 2013/PRO

Note that this applies only to CodeTwo Exchange Rules 2013 or CodeTwo Exchange Rules PRO installed on Exchange 2013.

Please be advised that installing the Service Pack 1 update on Exchange 2013 has been reported to cause transport agent failures (for more information see this TechNet thread). It has been just confirmed that upgrading to SP1 with CodeTwo software being installed may stop the Exchange Transport Service on a given server.

Due to the above, we recommend putting off the installation of SP1 until the problem is resolved. Chances are that Microsoft will release an update that fixes the issue in a few days. Nonetheless, we are currently working on our own fix that should be available soon. Please check back on our blog for future updates – we will post an update as soon as we know more about the issue.

If you have any questions, please contact our Support Team directly. We are sorry for any inconvenience caused.
