Shared mailbox not shown in Shared folder on On-premised Exchange server
Hi, I created a user account and assigned Office 365 license to it. It is shown in the Mailbox on both of On-Premises Exchange server and online Office 365. Then I converted the mailbox to Shared...
Your experiencing having duplicate mailboxes, it happens often when you assign licenses to someone that has onprem mailbox then you enable their license it'll create a mailbox in 365 and pretty much duplicating it.
Here is a blog post about it. Be careful to see what mailbox your user is using, you may need to export one of them first before doing this so you do not lose data etc.
