Overview

The members' synchronization may fail because of many invalid email addresses:

Unable to synchronize list '<list name>' because the following exception was thrown:
Too many invalid email addresses found in query results. Aborting synchronization.

You might need to temporarily prevent the synchronization from stopping, until, say, the incorrect emails are deleted.

Solution

Take the following step in the ListManager's web interface:

1. Select the list for which you want to change the synchronization behavior.
2. Go to "Members : Synchronization Settings".
3. Set "Terminate synchronization" to "Do not terminate synchronization due to malformed addresses".

Testing

The next time the synchronization runs, it will not stop because of the malformed addresses.
