Not using any native powershell cmdlets. Powershell cmdlets are basically to administrate the Exchange server, mailbox or even export the set of mailbox items to a PST file but not individual emails to dump to a network drive...

Perhaps you would need develop a custom program which uses Exchange Web Services to look the data inside a mailbox and export items to the network drive, try posting this in Development forum to see anything helpful there.... https://social.technet.microsoft.com/Forums/exchange/en-US/home?forum=exchangesvrdevelopment

Or a third party tool such as : http://www.techhit.com/messagesave/

Hi,

Based on my knowledge, there are no such commands to achieve your goal.

As a workaround, if you want other user to access those items, you can use Microsoft Exchange PST Capture to migrate data stored in PST files to user mailboxes is a two-step process. First, you create a PST search that locates the PST files on specified computers on your network. Then, you can import these PST files to specific mailboxes in your organization.

Or you can use assign delegates the following permissions to access mailboxes on behalf of mailboxes or groups: https://technet.microsoft.com/en-us/library/jj919240(v=exchg.150).aspx

Hi David,

Adding to what Amit said.

You can use PowerShell on the exchange server to export the Inbox data into a UNC path PST file.

New-MailboxExportRequest -Mailbox Kweku -IncludeFolders "#Inbox#" -FilePath \\SERVER01\PSTFileShare\Kweku\InPlaceHold.pst

More examples here:

For PS on the user side with Outlook installed.

Agree with the others, only format you could export to via Powershell is PST.  If you wanted them in MSG format you could do so via Outlook or a 3rd party product like DigiScope

Thanks for the ideas, guys.
In this case, I must using PST.

I appreciate everyone's attention.
