Not able to view shared outlook calendar
She has reported that at certain times she is unable to open a calendar she has permissions to. She gets a message - " Unable to open folder".
If she tries again an hour later or so she is able to open the calendar. Why is this issue occuring and why is it intermittant? I have tested by setting up an identical test environment and had no issues sharing calendars. No one else seems to have this issue except the user in question and also the user who's calendar she is opening.
The calendars that she needs to view belong to users who also use blackberrys. Could this have something to do with it? Is there a configuration problem between our blackberry server and exchange server?
Any thoughts or input would be greatly appreciated.
Thank you.
Platform: Exchange server 2003, Outlook 2000 clients, Blackberry Enterprise Server Management 3.6.7.12 running on Windows 2000 Server
