Can I recover and import `.pst` files to the Exchange Server that were backed up with OBRM?

It is possible to import previously recovered `.pst` files to Exchange Server.

The operations may differ depending on the Exchange Server version. Links to knowledge base articles are provided below:

  1. Exchange Server 2007 SP3, Exchange Server 2007 SP2, Exchange Server 2007 SP1: https://technet.microsoft.com/en-us/library/bb691363(v=exchg.80).aspx
  2. Exchange Server 2010 SP3, Exchange Server 2010 SP2: https://technet.microsoft.com/en-us/library/ff459261%28v=exchg.141%29.aspx
  3. Exchange Server 2010 SP1: https://practical365.com/exchange-server/exchange-2010-import-pst-files-mailboxes/

Note, that for the command:

 New-ManagementRoleAssignment Role "Mailbox Import Export" User Administrator one should use valid domain administrator credentials. Example: 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):
for example:

 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 non-shared folder, i.e. C:\Users\administrator.mydomain\desktop\, try following command:

New-MailboxImportRequest -FilePath\\127.0.0.1\C\$\Users\administrator.mydomain\Desktop\john.smith.pst -Mailbox john.smith
