Hi. Somehow the UR8 for Exchange 2010 overruled our patch schedule last night, and installed on 3 Exchange 2010 servers. After that I'm getting quite alot of strange problems on the Outlook clients connected to these servers, i.e. it fails when trying to reply to sent mails, typically the same message as if someone has sent mails to far too many recipients;
0x80004005-00000000-00000000 <-- When googling this, it returns hits like these; Error is [0x80004005-00000000-00000000]. Some articles i found were pointing to max. recipients limits issue.
However, the max recipients limits and similar were definitely NOT the issue right then.
Anyone experienced the same?
