Converting a Linked Mailbox to a user mailbox (ex2016-hybrid-mid-migration)

Question

We are migrating to o365, from exch2016. I have a user account who's mailbox is linked rather than a standard user mailbox. We are single forest, single domain. I've a feeling either this is a hangover from a previous exch upgrade, or it was a bodge at some point in the past, as the linked user account (which is usually disabled), has been enabled and the user logs on with this. As we are migrating, the user (being a linked mailbox) is not seen by o365 mailbox users (which is as expected). What is the best way to convert this mailbox to a user mailbox? I have seen "set-user -identity user@keyman .com -LinkedMasterAccount $null" as a solution, but is this the best solution? Kind Regards, Steve

@steve leggatt

The correct way is using the Set-User command to convert this mailbox as you found, but this action will lose some permission, you may need to have a check about it before covering mailbox：

Hi KyleXu,

I thought as much, however, it is always best to check things out first!
