Problem

Applicable To: This procedure works on all versions of Exchange Newer than Exchange 2010 SP1 (update rollup 8). If your Exchange server is OLDER than that you will need to use the following link;

Exchange 2007 / 2010 (Pre SP1)- Export Mailbox’s to PST files

The following procedure exports a user mailbox to a PST file on a network share.

Solution

Note: Not Even ‘Exchange Organisation Administrators” have the right to import / export mailboxes, you need to grant those rights to your user object, (or a better approach would be to create an admin account just for this purpose, then delete it when you are finished).

[box]

New-ManagementRoleAssignment –Role "Mailbox Import Export" –User {username}

[/box]

Note: This grants import, and export rights.

Create a file share on a drive with plenty of space, ensure the Exchange Trusted Subsystem has read / write access. And ensure the SYSTEM account has full control.

To create the ‘Export Request’

[box]

New-MailboxExportRequest -Mailbox “mailbox-alias” -FilePath \\server-name\share\file-name.pst

[/box]

Note: Add “-IsArchive” to the end of the command for Archive Mailboxes.
Note2: If the export repeatedly fails, add -BadItemLimit 200 to the end and try again, you can also use the -AcceptLargeDataLoss in exceptional circumstances

To view progress;

[box]

Get-MailboxExportRequest
OR
Get-MailboxExportRequest | Get-MailboxExportRequestStatistics

 

[/box]

When complete, you need to remove the move request(s);

[box]Get-MailboxExportRequest | Remove-MailboxExportRequest
OR (If you still have movement requests running)
Get-MailboxExportRequest -Status Completed | Remove-MailboxExportRequest[/box]

Using Content Filters

You can specify a content filter to only export emails after a certain date all mail received after 01/01/17 e.g.

[box]New-MailboxExportRequest -Mailbox {mailbox-alias} -ContentFilter {(Received -lt ’01/01/2017’)} -FilePath \\{server-name}\{folder}\{file-name}.pst[/box]

Or to export emails between two dates;[box]New-MailboxExportRequest -ContentFilter {(Received -lt ’31/12/2018‘) -and (Received -gt ’31/12/2017′)} -Mailbox {mailbox-alias} -FilePath {server-name}\{folder}\{file-name}.pst[/box]

Using IncludeFolders (and Exclude Folders)

You can specify IncludeFolders (or ExcludeFolders) to only export emails from certain folders, e.g.

Only export Inbox (and sub-folders) and Sent Items;

New-MailboxExportRequest -IncludeFolders “#Inbox#/*”,”#SentItems#” -Mailbox {mailbox-alias} -FilePath \\{server-name}\{folder}\{file-name}.pst

Don’t Export Sent Items and Deleted Items;

New-MailboxExportRequest -ExcludeFolders “#SentItems#”,”#DeletedItems#” -Mailbox {mailbox-alias} -FilePath \\{server-name}\{folder}\{file-name}.pst

Export ALL Mailboxes to  PST

[box]foreach ($Mailbox in (Get-Mailbox)) { New-MailboxExportRequest -Mailbox $Mailbox -FilePath “\\{server-name}\{folder-name}\$($Mailbox.Alias).pst” }[/box]
