We have an issue that is driving us insane. I have read though the forums and have had no luck with the suggestions.
Issue: We have had 200+ Outlook 2010 clients stop updating their mailboxes in cached mode. These seems to be caused randomly and we have not been able to find a pattern. The only way that always fixed the issue is deleting the OST file and letting it rebuild. It may resolve it self after a few days but we are unsure of that.
Environment: Windows 7 SP1, Outlook 2010 SP1, Exchange 2007 SP3, Most clients are on laptops
Any sugggestion will help.
