Event ID: 6205 Source: Marc3Host

Plugin DSScheduler reports exception.

Data Sources: Cannot open data source.

Additional info: External component has thrown an exception.
I have found that this error can be caused by a malformed or corrupted e-mail that ends up in the archive of the exchange journaling mailbox which cannot be moved by MARC 3. Possible Solution: Delete or move the oldest e-mails from the mailbox archive and restart the MARC 3 services. This can also happen if a rule has been set up to not allow archiving for a certain folder.
In my case, restarting the GFI MailArchiver v3 service solved the problem.
