I'm getting the below error trying to access Outlook Web and also Activesync isn't working.
I have a SBS 2010 Box. The last thing i did to the box was uninstall TrendMicro. I didn't know the uninstall password so i used an uninstall tool.
I've tried removing and recreating the OWA virtual directory. No good.
There is only one server.
Outlook Web Access could not find a mailbox for Domain\Username. If the problem continues, contact technical support for your organization and tell them the following: The mailbox may be stored on a Microsoft Exchange 2000 or Microsoft Exchange 2003 server, or the Active Directory user account was created recently and has not yet replicated to the Active Directory site where this Client Access server is hosted.
