Hi All

I am using exchange 2016 hybrid environment, i have a shared mailbox created in onprem and migrated to online. i am not sure if it is created as shared mailbox or remote shared mailbox.
i want to convert this shared mailbox to regular mailbox and assign license. In office 365 exchange admin center i can see the option to convert to regular mailbox.
i will convert to regular mailbox from office 365 EAC and enable the onprem AD account and reset the password. how about onprem exchange admin center will it show as a shared mailbox or regular mailbox. i dont see any option to convert to regular mailbox in onprem exchange. please guide me.

Hi @Glenn Maxwell ,
You could use PowerShell to convert it to a regular mailbox on-perm.

    set-remotemailbox <mailbox> -type regular

Take a look at these articles, which describe the mailbox conversion process. You'll need to use some PowerShell from the on-premises hybrid server.
