How do I clone a mailbox on Exchange server to create a second copy with the same contents?
We have a situation here at work that 20 years ago used to be something you could resolve with a simple powershell command, but nobody in our IT department can figure out how to do it under Office 36...
The only option natively in Exchange Online to export a mailbox is to use eDiscovery to export to PST then use the bulk import PST in purview to import into another mailbox.
You could migrate the mailbox back on prem and use the Exchange Server export cmdlet to export to PST and then use the same import service to import the data into a mailbox in EXO.
