Blackberry Bold -> Had 3 BIS e-mail accounts configured 1 of which was work e-mail address using Outlook OWA -> Using DM sync'd Contacts, Calendar, Tasks -> Upon doing so, Work calendar was erased within Outlook.

Upon further troubleshooting, found that my default calendar was set to my comcast address. (Found by going to Settings-Options-Advanced Options-Default Services). Everything in my work calendar now resides on a calendar called "Device Default".

I have tried to Sync calendar with Outlook, but being nothing is in there, it sync's nothing. I tried sync'ing to Yahoo, same result.

I setup a BES at my office, and went through Enterprise Activation. I now have e-mail and contacts, however still no calendar since it was previous wiped(Moved) to Device Default.

How can I retrieve my Calendar Appointments from Device Default and put them in my Desktop Calendar (CICAL).

P.S. There is no CICAL for Blackberry Internet Services within my Service Books

try redownloading it

If all your appointments are still in Outlook use the desktop manager to clear your calendar (using the advanced option inside Backup/Resotre) then re-sync with Outlook.
