How can you move all emails from one folder to another in Exchange Online?

Hello, 

I am trying to figure out how to move ALL emails from one folder to another (within the same mailbox) in Exchange Online.


When we did a PST import to O365, New folders such as "Inbox_0" and "Sent Items _0" were created. The imported emails did not merge into Inbox and Sent Items as we had expected. I need to move the emails in those folders to the "main" Inbox and Sent Items folders.. It should be a simple thing.... or so I thought. 


I know it can be done with Outlook, but takes forever that way when dealing with thousands of emails. I tried OWA, thinking that might be better, but in fact its worse, as there is no option to MOVE emails, once you "Select All" in a folder. It's just not feasible to select batches at a time, when you're dealing with thousands of emails. 


Is there a way to do this in Powershell?  I tried using the "Search-Mailbox" Powershell Command, which looked promising, but it would not le me use the same Identity as both a Source and Destination.   

Any advice would be most appreciated. Thanks very much.

I think the only PowerShell method I am aware of would use the outlook com object (basically what you do in outlook) so I doubt it would be any faster.
If you wanted to give it a try there are several scripts out there that will do something like this.
for example here is a technet article where the answer tells how to do this.

You can create filter "move" or/and "copy" and then execute "apply filters".

Thank you all for the suggestions. I have not had any luck yet getting EWS script to work, but that does seem like it should do what we need.. I will keep trying.  Thank you.

I was able to get the Merge-MailboxFolder.ps1  script to work properly. Thanks very much for the help.. That did the trick!
