Exchange 2013 SP1 Bug Fixes

You can review the bug fixes that are also covered by this release, which is effectively Exchange 2013 CU4. See the KB page (with download link inside) here: Exchange 2013 SP1 is a full build release, and requires an Active Directory Schema upgrade, as per all Exchange 2013 CU releases. The next CU release for Exchange 2013 is CU5.

Exchange 2013 Edge Transport Role

We are most interested, from a migration point of view, in the re-appearance of the Edge Transport Role. Reading the Microsoft link for Exchange 2013 Edge Transport ( there does not seem to be detail on new features above what was available in Exchange 2010 Edge Transport. However, Edge Transport does provide useful features for a migration, such as Address Rewrite.

Exchange 2013 SP1 Migration Milestone

Exchange 2013 SP1 is an important milestone for those wanting to migrate off their current mail platform. SP1 is often treated as being the first production version of any Microsoft Exchange release – in my experience anyway. This means we expect a number of Exchange 2013 email migration projects to get underway now – at least after Exchange 2013 SP1 has been out for a few weeks, in case there are any issues with it.

As ever, if you need consulting for your email migration project to Exchange 2013 SP1, then please contact us.
