Any chance the user is hidden from the address book? This is exactly the behavior I would expect in that case.

I have one user who cannot open Outlook. Attempts made on multiple machines, including machines he's never logged into before, always the same message: --------------------------- Microsoft Outlook --------------------------- Cannot start Microsoft Outlook. Cannot open the Outlook window. The set of folders cannot be opened. You must connect to Microsoft Exchange with the current profile before you can synchronize your folders with your Outlook data file (.ost). --------------------------- OK --------------------------- User gets in fine with OWA. I've used various command line switches for Outlook, including /resetfolders, /resetfoldernames, /resetnavpane, etc. I've tried turning cached mode off and on, using encryption and not, and deleting both the Outlook and Windows profiles. Nada. I see nothing in the workstation event logs, nor anything on the CAS or DB server event logs either. Nothing seems amiss via the Exchange GUI. I'm going blind looking at google, too. Anyone have something else I can try? I'd prefer not to export to PST and nuke the mailbox, but it might come to that. Kurt
