GASMO authentication issue with Google Drive disabled users
Users of Google Apps Sync for Microsoft Outlook (GASMO) version 3.8.430.1200 who also have the Drive service disabled will be continuously prompted to re-authenticate.
How to diagnose:
The Drive service will show as ‘Off’ on the affected user’s overview page within admin.google.com.
When the user attempts to sync using GASMO the dialog box ‘Please sign-in to Google Apps Sync’ will be displayed. After successfully signing in the dialog will continuously re-appear.
There are two workarounds:
1. Enable the Drive service for GASMO users. To do so please see the Help Center article ‘Turn Drive on or off for users’ at https://support.google.com/a/answer/6115117.
2. Disable GASMO Notes sync. To do so please see the Help Center section ‘Disable sync for a specific product’ at https://support.google.com/a/answer/1041455. Specifically the registry keys that should be created are the following:
HKEY_CURRENT_USER\Software\Google\Google Apps Sync\DWORD:SyncFlagsEnabled with value 1
HKEY_CURRENT_USER\Software\Google\Google Apps Sync\NotesSync\DWORD:DownloadEnabled with value 0
HKEY_CURRENT_USER\Software\Google\Google Apps Sync\NotesSync\DWORD:UploadEnabled with value 0
Note that if you are running a 32-bit version of Outlook on a 64-bit installation of Windows the registry prefix will instead be HKEY_CURRENT_USER\Software\Wow6432Node\Google\.
