I am going through the steps and on Step 7 I am having an issue. I am running it on our On Premise Exchange Powershell and I am getting:

The operation couldn’t be performed because object ‘NEWUSER’ couldn’t be found on ‘ONPREMDOMAINCONTROLLER’.

I changed the names in the error to something generic. I’ve tried several things for -Identity in the PowerShell command but I get this error for everything I try. I can run Get-ADUser NEWUSER and get results but not when running the Enable-RemoteMailbox command.

Do you have any ideas?

[Hybrid enviorement]
Is there a way to enable remote mailbox without EMS?
We don’t have it here and need to separate a mailbox from a user.

thanks in advance.

Hi Matthew,

Did you ever figure out how to fix the issue with losing Teams data when a new account is being used? I am also going to perform this process with the mailbox and want to be prepared if this happens with Teams. Thank you

I have a little twist in this scenario.

Parent company: Office 365 tenant
Parent company : AD connect setup
Child Company: separate AD
Child Company: AD objects synced to parent company AD Connect
Child Company: mailboxes migrated from Exchange On-premises to Parent company’s Office 365 Tenant.

What we would like to do is re-create users for child company on parent company’s AD, detach mailboxes that are on Exchange online from child company users accounts and re-attach to newly created accounts on parent domain AD. I tested it and it work but I don’t have Exchange in my test environment to see how the attributes are affected.

Any guidance will be appreciated

I appreciate your interest in my blog! Microsoft Teams is a combination of many products, like exchange online, OneDrive & SharePoint. I am not familiar of any way of migrating a Teams account to an other user as is. You can copy the OneDrive data, change access to SharePoint, migrate the mailbox (as described here), but I don’t know if you can migrate more Teams related data.
Somethign like this: https://answers.microsoft.com/en-us/msteams/forum/all/teams-migration-from-one-account-to-another/4d5f7542-14f7-452a-b618-758dcd8cf629

The NEWUSER essentially started as a brand new Teams account.

In my scenario the NEWUSER was already created when I started the process though. If you have thoughts on that I would love to hear them but more just putting this here for anyone using this guide in the future.

Then you need to create a new user to take over the shared mailbox.
In high level:
1. Create a new user “shared1”
2. disconnect the mailbox from “user1” and connect it to “shared1” (follow the process of the article)
3. convert the “shared1” to shared mailbox
4. re-enable the sync for “user1” and it enable remote mailbox for “user1” to have a new mailbox.

Hi Cassio,

Is it a cloud only schenario or a hybrid?

In my case, I need to disconnect user’s mailbox “user1”, and connect to a new shared mailbox “shared1” and create a new mailbox for “user1”.

it’s possible?
