Released: Update Rollup 4 for Exchange 2010 SP1

Rollup 4 introduces another bug, when copying folders to a PST, only the folder survives.

Guys, this is getting beyond a joke, how many rollups and intrim fixes to we need to apply? We applied RU4 from RU3.3 to fix a major issue with migrating users from 2003 to 2010  now to find out Ru4 has introduced another bug.... so now I am 90% into my migration of 4000 high profile users and I now find out I have yet another issue? This is becoming extremely tiring, can you guys just get at least one rollup right? Ru3 was a joke, Ru 3.3 then came out, then a few weeks later I had to repatch all my servers again with Ru4 (which requires a LOT of work after hours for myself).. Seriously guys get it right please. Can you address this issue ASAP? We are a major international corporation, having just finished the migration for APAC to ex2010 and now at the tail end of EMEA migration, we are now halting migrating users in our Americas site because of this. - Extremely frustrated chris
