connection to the Microsoft Exchange Server is unavailable. Outlook must be
online or connected to complete this action." System can send and receive.
Also "Resource Scheduling" button is grayed out in Tools>Options>Calendar

Did you try a new profile? Is outlook online? Is there a firewall enabled on
this computer?

No I haven't tried a new profile. Yes Outlook is online, wifi if the PC is on
in this bldg its online. Symantec corporate firewall, we have 3 identical
laptops, same software, this is only one with issues.
