The Archive Manager console (Enterprise Manager) is starting in Read-Only Mode (4277259)

The application is opening in read-only mode and does not allow editing settings or archiving items.

Only one Enterprise Manager can be in full mode. If multiple users started it, the first one will be in full mode and all others in read only mode.

Also, if the licensing info is duplicated due to a server migration, this might happen. If it does, you need to contact the Licensing Team to have them reset your license count.

• Make sure that no one else is connected to the Archive server and running Enterprise Manager. If possible, disconnect other users from the operating system.
• Make sure that the license has not expired or the license limit has not been reached. To check the license, open Enterprise Manager, click Help > License.
• Restart the MAM Exchange Manager (MAMExManagerSv) service and launch Enterprise Manager again.
