How to import Microsoft Exchange Server mailbox data from PST files backed up by Online Backup and Recovery Manager?

It is possible to import previously recovered PST files to Microsoft Exchange Server.

The operations may differ depending on the Exchange Server version:

Note, that for the command:

New-ManagementRoleAssignment Role "Mailbox Import Export" User Administrator

one should use valid domain administrator credentials.

New-ManagementRoleAssignment Role "Mailbox Import Export" User mydomain\Administrator

After the command is completed, close and re-open the Exchange Management Shell.

For New-MailboxImportRequest, UNC path is required (SMB share on the local machine, other machine or NAS at the local network).

New-MailboxImportRequest -FilePath \\esp-ho-ex2010a\pst\john.smith.pst -Mailbox john.smith

General pattern

New-MailboxImportRequest -FilePath \\SHARENAME\Folder\filename.pst -Mailbox mailbox_name_or_alias

If a file is placed in a non-shared folder, that is C:\Users\administrator.mydomain\desktop\, try the following command:

New-MailboxImportRequest -FilePath \\\C\$\Users\administrator.mydomain\Desktop\john.smith.pst -Mailbox john.smith
