Multiple mailboxes on this database have been quarantined. |
Explanation
This message indicates that a mailbox in the database has been quarantined. By default, if a mailbox is identified as causing a crash or a deadlock three times within two hours, the Exchange store tags it as quarantined in the registry.
User Action
After the cause of the poison mailbox is determined and corrected, the registry key for the quarantined mailbox should be reset manually by deleting it. However, if this manual step is forgotten, the Exchange store automatically resets any quarantined mailboxes six hours after the quarantined flag is set. If the issue has not been debugged and fixed within that time period, this may lead to another set of crashes before the mailbox is quarantined again.
Note
The database hosting the mailbox must be remounted or the Exchange store must be restarted for the quarantined mailbox to be reset.
