Exchange 2010 sp2 on SBS 2011

So far the only Exchange 2010 sp2 official post known issue I've seen is this:

Event ID 4999 is logged on an Exchange Server 2010 Client Access server (CAS):
http://support.microsoft.com/kb/2665115/en-us?sd=rss&spid=13965

I've seen a few folks report a bit of bumpiness getting it installed on SBS 2011 but I've not see any abilty to repro this issue.  Like anything, have a backup before you plan to roll it out.

Last week I did a clean install of SBS2011 and I went ahead and put E2010SP2 out there and it went through like a champ.

We "lost" our SSL cert.  It reverted to previous ones (non SAN, so useless on Exchange 2010/Outlook 2010) installed in October 2011.

I recreated CSR exactly as I had before, got a duplicate cert from our cert provider, assigned services (again) and all was good.

Definitely a bug.

Hey Indy?  Can you email me your Exchange setup log to susan-at-msmvps.com?

Hey at all,

we lost NOT our certificates on 3 SBS 2011 Servers, from us, no problem.
