The error posted above is related to PIM/Outlook Notes/BB MemoPad synchronization. It really doesn't have anything to do with your stated issue, which is related to e-mail reconciliation.

I can't post links yet, but if you already haven't done so, I'd recommend you look at KB10939 (Troubleshooting wireless email reconciliation on the BlackBerry smartphone) on the BlackBerry Technical Solution Center website...

Regarding the Memo issue. Rather than play around with MFCMAPI, an easier test is to right-click on the affected folder(s) in Outlook. If the folder can be renamed/deleted, it's not a true system folder, and the BES will not be able to synchronize with it.

If this occurs, you can rename the folder (Notes1), run Outlook with /ResetFolders, and copy the data from the renamed folder into the regenerated Notes folder in Outlook. The error message should no longer occur, and the affected user will have wireless reconciliation on the affected folder.
