5.2.1: Mailbox cannot be accessed

Possible Cause:

The mailbox cannot be accessed. The mailbox may be offline, disabled, or the message has been quarantined by a rule.

Additional Info to solve:

Check to see if the recipient database is online, the recipient mailbox is disabled, or the message has been quarantined.

Solution using command:

Mailbox cannot be accessed. Perhaps the message is too large. Alternatively, the mailbox has been disabled, or is offline. Check the recipient's mailbox. Else it could be a permissions problem, particularly on a Public Folder. If so, try this PowerShell Command:

get-PublicFolderClientPermission "\ProblemFolder"
