Title
Migration Manager for Exchange 8.11 license may be consumed twice for the same mailbox -
Description
Migration Manager for Exchange version 8.11 and earlier can consume the license twice for the same mailbox in the following cases:
- If you move the mailbox in the source environment between servers.
- If the mailbox is hosted by an Exchange 2000 or 2003 clustered server and a failover operation occurred during migration.
- If the mailbox was processed by several Mail Source Agents (MSA) or Migration Agent for Exchange (UnifiedSync) installed on different servers, used as agent hosts for the source Exchange server.
The above is not valid for Migration Manager for Exchange version 8.12
-
Cause
License counting algorithm in Migration Manager for Exchange 8.11 was designed in this way. Migration Manager for Exchange version 8.12 uses a different algorythm and the issue doesn't occur any more.
-
Resolution
Run the License Reporter Utility on all agent hosts and provide the output together with the original license file to support for assistance.
The License Reporter utility can be downloaded from https://support.quest.com/kb/SOL32695.
