Software requirements for mailbox restore operations

Edit online

When you restore mailboxes and mailbox data, you can choose where to restore the mail and how to restore the mail. You can restore mailbox data from the GUI or command-line interface.

From these interfaces, you can restore data interactively by using the Mailbox Restore Browser or directly from Exchange Server database files. When you restore mailboxes and mailbox data on Exchange Server 2013 or later, ensure that your environment is set up to meet the following requirements:
  • Ensure that the administrator account that is used to perform the mailbox restore operation has an active Exchange mailbox in the domain.
  • Ensure that the user name who is logged in has role-based access control (RBAC) permissions to complete individual mailbox restore operations.
  • Ensure that the directory where you restore a mailbox has enough temporary disk space to store the entire mailbox database and log files. To specify the restore directory path, use the following settings on the General property page for the Exchange Server workload:
    • Temporary Log Restore Path
    • Temporary Database Restore Path

    If you do not specify a directory, the database files are restored into a directory that is specified by the TEMP environment variable.

  • Exchange Server 2013: Ensure that the correct version of Microsoft Exchange Server MAPI Client and Collaboration Data Objects is installed on the Exchange Server that you use to run the mailbox restore operations. The correct version is identified in the Hardware and Software Requirements technote that is associated with the level of your software. This technote is available at this web page: All Requirements

    Follow the link to the requirements technote for your specific release or update level.

  • Exchange Server 2016 or later: Install Microsoft 32-bit Outlook 2016 or later version as the MAPI client on the same server that Data Protection for Exchange Server uses for mailbox restore operations.

The amount of time that is needed to complete the restore process depends on the size of the mailbox databases, the network speed, and the number of mailboxes to process.
