Issue: Users using BB and sending update meeting notice of any kind recurring or normal are having issues. The original meeting request is not being deleted andupdate notice is also showing up in the calendar of the user who has sent out the update notice.I used MDBVU to delete the corrupt items in the folder MAPI_Folder - Blackberryhandheldinfo\BlackBerryCalSyncState. I see lot of corrupt items in this folder which says BlackBerryCalSyncState Folder. I deleted these but they come up after every few hours again. In hundreds not anything less than few hundreds. Any help will be greatly aooreciated. Due this i see users complaining variety of issues. I see calendar items which should be showing up as tentative but not showing up in calendar as tentative. Updated notices do not get deleted. Not sure how to get this fixed. Thanks for any help !

Hey Shiv, How did you verify that it has corrupted items? It is being created and used by blackberry agent so we might not be able to judge if it is corrupted since it is custom items and MFCMapi might not be able to display it properly. However deleting it might create issue with blackberry communication or data loss on it. Below article gives you insight...
