Sync problem- MAPI logon failed.....and try again.

Hi. I have been trying to sync my Bold 9700 with Outlook 2007 for the last 2 days and I get this error: MAPI logon failed. Please run outlook with the profile "outlook" selected and try again. My DM version software is 7.1, my device OS version is 6.0 bundle 3049 and running in Window 7 operation system. Can somebody help me to fix this error? This is the first time that happened to me in couple of years. Thanks

Re: Sync problem- MAPI logon failed.....and try again.

After searching out and installing some previous versions of Blackberry Desktop when I experienced this problem after the most recent upgrade of the software, I realized that the issue had to stem from some corruption, probably in the contacts section of my OUtlook .pst file. (I realized this because even very early versions of teh Desltop software--for example, version 4.7 with which it came originally--although they were able to synchronize apparently still noted problems with some individual entries.) My solution: I backed up the pst. file (and for good measure it would have been a good idea to export all of the information in it to some text format as well), and then removed all contacts from it inside Outlook itself. I was then able to get even the newest version of Desktop software to restore all the deleted information from the Blackberry, and have had no further problems with synchronization.

Re: Sync problem- MAPI logon failed.....and try again.

Please see my quick reply to the source post for this thread, since after much effort trying to find and restore earlier version of the Blackberry Desktop software, it appears that the real problem lay in corrupted data inside the OUtlook .pst file itself.  Once that was fixed, even the newest evrsions of Blackberry Desktop software perofmr the synchronization perfectly.
