Office 365 Migrations

[nathan]

Hi,

 

I've just used E-Discovery to export users emails etc into PST files which worked a treat. I've just opened one of those PSTs in Outlook and notice the emails that reside in Inbox are stored inside a folder called Primary Mail Box. So like the following;

 

Primary Mail Box

---Inbox

---Sent Items

---Deleted Items

---Outbox

 

Now when i go to import these emails back in using the import PST tool in Office 365 will it put another folder called Primary Mail Box in users accounts?

Try one. Might do.

From what you're saying yes, as I'd expect e-mails to be stored in Inbox typically. I presume when you open/import into Outlook 2016 this is what happens?

 

It may be a bit of work, but by importing into Outlook 2016, you can quickly bulk move e-mails into Inbox, then sync it back to the required O365 account in the cloud.

You can export pst files direct from Exchange using powershell, it is what I done for archive purposes before migrating student mailboxes over.

I agree, but the OP didn't mention anything about Exchange. I'm guessing the existing mail client is something third party that supports PST export (as do most applications).

There wasn't an easy way for this process unfortunately. We had to open each PST in Outlook and move all the folders out of the Primary Mailbox folder and into the root area. It's also worth noting that this doesn't actually move the contacts and calendars. You have to right click on both and select move. If you don't do this last step you end up with a duplication of both.
