Can I delete these SystemMailbox from Exchange? They say legacy and have multiple warnings
Hello
I am trying to wrap up a migration from Exchange 2010 to 2016. I tried to remove an old BES throttling policy and it complains about still being associated with these mailboxes. I had noticed them before in the Exchange Admin Center but had ignored them up to now. What you can see in the Admin Center is they do not have any databases associated with them. I found the ID's in Active Directory under the Microsoft Exchange System Objects container and they show as disabled.
So my question is... can I delete these safely without destroying my Exchange environment!?
Thanks
Phil

Mine is called BESPolicy also. How would you run that script? Save it as a .ps1 file and just run it? Safe to run during the day?
What about the SystemMailbox - should I delete those afterwards?

I just ran the script. There are no mailboxes with the BESPolicy assigned. Now what do I do about the SystemMailboxes with the warnings?
If you ran the whole script it would have checked to see if it was associated to any mailboxes and then the last line was to delete the policy itself. Was the policy deleted?

Hello
I have completed most of those steps and my system mailboxes have all been moved to 2016. These appear to be random strange leftover mailboxes. I just wondered if anyone has ever seen them before and what the best way to delete is?
Thanks

Yes, I already migrated those. The names appear to be different.
