Troubleshooting error message -1 during an Exchange scan

Error -1 is usually received when Bitdefender tries to scan the Microsoft Exchange Public Folders and it lacks the appropriate access.

Error -1 may appear because the Public Folders are either not configured or there are errors in their configuration.

The best way to verify that the situation is indeed caused by Public Folders is to run a Bitdefender Exchange scan without this option enabled.

If you do not use Public Folders in your organization, start the Bitdefender Exchange scan without Public Folders.

If you use Public Folders and the error persists, make sure they are configured correctly. If the issue persists, contact Bitdefender Enterprise Support for further assistance.
