When I create a user on the Blackberry Administration Service, I get these errors in the event log:

MailStoreExchange::GetFolderRedirectionProperties - Error in OpenMsgStore, result=0x80004005.
MailStoreExchange::GetUserPrivateFolders - Error in OpenMsgStore, result=0x80004005.
GetPersonalEmailFoldersForRedirection failed for User id=15
MailStoreExchange::GetPersonalEmailFoldersForRedirection - GetFolderRedirectionProperties failed.
The user is created and the handheld can be activated correctly, but the Inbox folder and its subfolders will not be forwarded to the device.

I tried using MFCMAPI to erase the BlackberryHandheldInfo folder in the given mailbox (as I was instructed in blackberry forums), but I could not do that, MFCMAPI just quits unexpectedly. Any suggestions?
