The Microsoft® Exchange Server Analyzer Tool has determined that your server currently has a higher user load than it can support efficiently. The current user load is causing performance issues. It is recommended that you move users to another location by moving a small number of them (typically five percent of your total users) each night until the performance issues are resolved.

This approach is recommended because one of the following issues has occurred:

While the Exchange clients are not required to be disconnected from their mailboxes during a move mailbox operation, it is recommended that the move take place when Exchange client activity is low, such as off peak hours, to avoid possible service disruption.

  4. Right-click the selected users, and then click Exchange Tasks.

  5. In the Exchange Task Wizard, click Next.

  6. On the Available Tasks page, click Move Mailbox under Select a task to perform, and then click Next.
