Exchange/Outlook Issue

When trying to open a resouce calendar (permissions are correct), Outlook hangs for a while. The hourglass is replaced with the message. “the information store could not be opened”.

The resource responds when an appointment is scheduled. The calendar can be opened from the Outlook running on the domain controller.

Network Os is 2000 running active directory.

I’m not sure whether to look to Exchange 2K or outlook (also 2K).

Thank you,
