I am looking for a way to migrate an externally hosted Exchange mailbox into a new Exchange installation. The situation is basically this:
- Current mailbox is hosted on exchange 2016, but I have limited access to the Exchange configuration. Essentially, the only access I have to this mailbox is through the email client I use for it.
- New exchange installation is fully managed by myself and I have full access to it all.
I'd like to programatically be able to migrate from the externally hosted into the new internally managed one.
I've seen various "free trial" software packages offering the ability to do this, but not much else.
Anybody done this before without additional software?
Thanks
