Glad to hear you have everything working. Tonight is our maintenance night and the mail team is installing the cdo.dll patch on the rest of the mail servers. Several of the servers were using the older 5.5.2653.12 version of cdo.dll.
So they'll update the servers and then all the servers including BES get a reboot. So I'll see what happens after that. Everything was working fine, but I can't pinpoint when the calendar problems began.
Another symptom of the calendar issue is when creating an appt on the BB and adding an invitee. When you send it, the invite will return with a red X.
I just rechecked all account permissions and they are all correct. Just want to have everything lined up and accounted for if I have to contact RIM tomorrow.
Thanks for the update.
