Update Rollup 10 for Exchange 2007 Service Pack 3 is now available for direct download. As it also contains a security update, it’s directly being offered via Microsoft Update as well.
In addition, this Rollup also introduces coexistence with Exchange 2013 so you can upgrade directly and skip Exchange 2010. That is “almost directly”, as you need to wait for Cumulative Update 1 (CU1) for Exchange 2013 which is due this quarter as well.
In addition to the above updates, this update also includes the following:
- KB2783779 A hidden user is still displayed in the Organization information of Address Book in OWA in an Exchange Server 2007 environment.
- This update also includes new daylight saving time (DST) updates.
