We have had EXchange 2010 stock clean install out of the box since January, hoping the default settings would finally bring us a nice healthy exchange after recent mgration from 2007. NOT HAPPY :-(
My biggest headache is the OAB. I have run through all the guides on how to recreate, regenerate, redistribute the OAB, and before I go tinkering with IIS settings, I need some qualified guidance. It was working about a month ago after the same issue appeared and doing the above we finally started seeing new users in OAB/cached mode.
Then I started seeing the dreaded "Microsoft Exchange offline address book, 0X80190193" in my Outlook sync log, and I have tried everything and the only fix/workaround is to manually delete users .oab files on their pc. This is not a solution, but confuses me more. Because obviously users can connect to OAB and download fresh copy if i delete their .oab files, but after the first time those .oab files never update again. Manual Address book downloads NEVER work.
Before i go fiddling and changing intricate permissions/auth settings in IIS and possibly mess up more stuff and start makinga mess of an otherwise clean install, I need to get to the bottom of OAB issue. Its such a fickle bastrd ye 'ol OAB, why oh why?!?!?!?
My last/safe/clean effort was completely removing the OAB from EMC, the also removing/deleting the virtual directory. Then recreating both cleanly using the shell's default setting. Nope. Exact same problem.
HELP
