How to fix: An error occurred while syncing the Data - User canceled authentication
The error below is associated with BrandMail not being able to successfully authenticate, as a result of the Microsoft authentication pop-up being dismissed by the user.
This authentication method requires you to click on your email address when the pop-up below appears. This pop-up will appear every 30 days. If you do not click on your name to authenticate, your BrandMail will not be able to synchronize and appear "stuck". After a number of predefined days, the database will lock.
In order to fix this issue:
1. Restart your workstation (and specifically Outlook)
2. The above pop-up should automatically come up
3. Click on your email address to authenticate
4. Click "synchronize data" to restore your database and access to your templates (including your email signature):
NOTE: If the Windows pop-up does not automatically appear after restarting Outlook, please click "synchronize data". This should force the pop-up to come up.
