I'm currently running 2010 SP1 RU3v3 and tomorrow I have a maintenance window scheduled. Now, other than BES Express there is nothing that is "linked" to Exchange beyond our regular Outlook/ActiveSync/Webmail clients. I'm inclined to go to SP1 RU6 for now, and jump to SP2 in the next maintenance window (we don't work weekends so scheduling one is not a big deal). I guess my question is, assuming you don't have a dependency on a particular version, what is Microsoft's best practise on where to be in terms of Service Pack + Rollup level please? Thanks, Paul

Thank you both - I'll likely stick with SP1 RU6 for now. Just to confirm as well, I have a bunch of Windows Updates for 2008 R2 that need to be installed. Many relate to .net - anything to be wary of with regard to Exchange 2010? http://support.microsoft.com/kb/2540222 is all that I can find.

There's no need to install a newer release of .Net so don't do that. All the rest of it is just the same as any other set of hot fixes and security update -- install them on lab servers first. That'll give you a fighting chance of finding the really obvious problems. like the one described in that KB. --- Rich Matheisen MCSE+I, Exchange MVP --- Rich Matheisen MCSE+I, Exchange MVP

Thanks Rich, we didn't have .net 4.0 on the server so I didn't install it (and nor did Microsoft/Shavlik suggest it). I went to SP1 RU6 and I'll pull the trigger on SP2 RU3 in a couple of weeks once I've read up on any gotcha's as that one does seem like there's no way back - thanks very much :)
