Title
MAgE Native Move Job fails with Error: "This mailbox exceeded the maximum number of large items that were specified for this request" -
Description
Certain mailboxes in a MAgE Native Move Job may fail to move with the agent log reporting an error code '-2146233088' and message text 'Error: This mailbox exceeded the maximum number of large items that were specified for this request.' -
Cause
One or more messages have exceeded the message size limits defined in the Target Exchange's Organization Transport, Receive Connector(s), Send Connector(s), and / or on the Recipient Mailbox itself. -
Resolution
In Target Exchange, review and adjust, as needed, the configured message size limits in the following areas:
- Organization
- Send Connectors
- Receive Connectors
- Recipient Mailbox
The order of precedence that Microsoft uses is the most restrictive applies first.
Once message size limits have been adjusted appropriately, you must remove the Move Request using Exchange Management Shell (EMS):
Remove-MoveRequest -Identity
Then select Retry Move for that mailbox in Migration Manager for Exchange.
To understand Message Limits, please review the appropriate Microsoft document that corresponds with the Target Exchange version:
