I opened a support request with MS for: Move After 14 days all items in the folder "deleted items" to the archive. 

- But after two days I noticed that the emails were moved "after 14 days" of the "all folders", moving approximately 90% of the emails from all users (roughly 2GB each user). 

- How do I export a mailbox (with sub folders) to pst file (by powershell)? 
- After, i can to import this pst file by powershell to mailbox?! 
- Or I can undo what has been done and return the emails to the main box?

Thanks.

- - My system:
Office 365 
Mdulo Windows Azure Active Directory para Windows PowerShell
All users are in the office 365 (I have no local exchange)
Dirsync, ADFS, DC in cloud (azure)

Hi,

You may try to run the following command:

New-MailboxExportRequest -Mailbox JSmith -FilePath "\\SERVER01\PSTFileShare\Jsmith.pst" -IsArchive

For more information, please refer:

If you need further assitance about the powershell command, you can post a question in Exchange forum:

Thanks Steve.

New-MailboxExportRequest is an Exchange 2013 command

This will no work for Exchange Online.

I don't think it is possible to export to PST from Exchange Online Powershell yet
