Exchange Server 2007 Sync Issue 0X80190193
There are a couple of things I did to resolve this issue for me:
1. Exchange Management Console -> Organization Configuration -> Mailbox -> Offline Address Book Tab, make sure this exists and the distribution is set to Web-based and Public Folders.
2. Exchange Management Console -> Server Configuration -> Mailbox -> Database Management Tab -> Mailbox Database -> Properties -> Client Settings tab, verify the OAB is text box is filled in, if not click browse and select your OAB.
3. IIS -> OAB Virtual Directory -> SSL Settings -> DO NOT REQUIRE SLL -> Restart IIS
4. Restart Outlook 2007/2003.
