Another bugy release. I know this was delayed, but really it should have been delayed another month at least. We had one server where, as Benoit suggests in this thread, had to have the entire EWS rebuilt. Now the latest is we are waiting on a post CU1 patch in order to backup the system. For some reason the backups are no longer working in this release, but they were in the rtm. OWA seems flakey and public folder support really doesn't work. Sharepoint integration for discovery also doesn't seem to work.
Total failure as far as I'm concerned. Exchange people have spent way too much time worrying about the cloud offerings and it shows. The on-premise version of Exchange, as it stands now, is the buggyst version of Exchange I've ever tried to use.
My only question is that will exchange finally get it right with cu2 or do we have to start looking at some other options here?
