Breaking News: Google Apps Sync may not work with Dell MessageONE Outlook Plug-in

If you are using the newest version of Google Apps Sync, you may receive this message:

There are many "fixes" posted online, about deleting the Google Apps Sync password, restoring the .pst file, etc., but the one that worked for me was disabling the Dell MessageONE Outlook add-in.

This problem can occur for both Outlook 2003 and Outlook 2007 users. Keep in mind, that you may need to create a generic Outlook account just so that you can get access to Outlook.

Disable Add-Ins in Outlook 2003: Tools > Options > Advanced Options > Add-In Manager. Uncheck the box next to "MessageOne Outlook Extension".

Disable Add-Ins in Outlook 2007: Tools > Trust Center > Add-Ins > (change the drop down list to) Exchange Client Add-Ins (click "Go"). Uncheck the box next to "MessageOne Outlook Extension".


The Dell MessageOne add-in is not needed when connecting to a Google Apps account (it is a continuity agent, but has security logging capabilities).
