Email Migration from Imap to Exchange
Ok like with every first time I am a bit nervous on this post but I hope I am doing everything right :D
My first problem:
I am trying to migrade Emails from two Imap accounts (all inkl) to our brand new exchange account. One of those migrations was a success and the emails where transfered to the new exchange account.
Well you can guess that the second one wasnt so great: no error accured and nothing seems different from the first migration just that there are no emails arrive on the new account.
My second problem:
We also need to migrate Emails from two IMAP adresses to two puplic mailboxes. For that we need want to use a special domain, I added the domain in Office365 but when I try to create a public mailbox it tells me that the used email adress is already in use from another source. I have searched every part of my office365 but the adress is nowhere used.
I wouldt be so happy if you couldt help me or just give some ideas cause I have run out of those.
greetings Chris

- Hi,
Email migration from IMAP to exchange will get you errors. Because O365 doesn't support imap created folders. Folders will be created but emails won't be migrated. I encountered this issue couple of weeks back when I had to migrate one of our clients emails. Here's what you can do to get the emails in the folders. Configure the new O365 account on Outlook. Press Alt+F11. Click on open new project
And follow the steps in below script. It works flawlessly! We had some 120-150 folders in each email accounts and emails were all missing. But we were able to retrieve it all with the help of the below.
Make sure you select " get folder " at the top of the script page and press run!

The missing items with IMAP dilemma might be due to the item class as detailed here: https://support.microsoft.com/en-us/help/3050475/you-can-t-view-mailbox-folders-on-an-exchange-activesync-or-outlook-cl
Or a bulk method here: https://www.slipstick.com/developer/code-samples/change-outlook-folder-type-export/
For the email address issue, simply check via:
Get-Recipient user@domain.com
It will return any matching objects.
For the first problem.
Did the user using / in the name of folders. Foldernames with a / in it will not be migrated. You will find an error mail in the source mailbox.
