Certainly.
Since I was getting rid of the environment anyway, I simply disabled the
arbitration mailboxes, which then allowed me to uninstall the mailbox roles
from those two servers.
Get-mailbox -Database "DB1" - arbitration | Disable-Mailbox -arbitration
-DisableLastArbitrationMailboxAllowed
There are 3 arbitration mailboxes by default:
Name DisplayName
---- -----------
FederatedEmail.4c1f4d8b-8179-4148-93bf-00a95fa1e042 Microsoft Exchange
Federation Mailbox
SystemMailbox{1f05a927-2a11-4a3c-94c6-d95b1b5f5c47} Microsoft Exchange Approval
Assistant
SystemMailbox{e0dc1c29-89c3-4034-b678-e6c29d823ed9} Microsoft Exchange
So, reinstalling the HT/CAS wasn't required.
Hope that helps.

I am saddened to report that I figured it out, and my on-prem Exchange
environment is completely uninstalled and removed.
A moment of silence please...

Subject: [Exchange] RE: Uninstalling Exchange environment
So, I found a cmdlet that I thought was going to resolve my issue:
Get-mailbox -database BBB -arbitration | remove-mailbox -arbitration
-RemoveLastArbitrationMailboxAllowed
However, when I run this command, I get this error:
"The arbitration mailbox "domain/users/FederatedEmail.xxxx" is used by Exchange
and can't be removed."
I'm still getting the error saying there's no server running the MRS as well.
Any tips?
Joe

I may have screwed up here. I got a little overzealous, and uninstalled all
HT/CAS servers before any MBX servers. So, when I tried to move arbitration
mailboxes, etc to empty out all mailbox databases except for one, there was no
servers to do this. D'oh! I reinstalled the HT/CAS roles onto one of the
boxes that previously held them. Now, when I try to move a mailbox, I get the
error:
"There aren't any available servers running the Mailbox Replication Service".
I've verified that that service is indeed running on the HT/CAS box. I've also
rebooted all boxes involved, still getting the error.
I tried checking MRS health, and got this:
[PS] C:\Windows\system32>Get-ClientAccessServer | Test-MRSHealth

You should cleanly uninstall Exchange.

If the VMs that Exchange was installed on, were not used by anything else, do I
still need to uninstall via Add/Remove programs? I'm thinking I should, just
to be safe, but my coworker is just wanting to shut down the VMs and remove
from disk.

If you think that there is ever any chance that Exchange will come back
on-site, then you should cleanly remove Exchange.
Leave the AD groups online. Ignore them.

Subject: [Exchange] Uninstalling Exchange environment
Now that we've been force migrated up to the state's O365 implementation, I've
been looking into how to go about removing my on-prem Exchange. First thought
was to simply shut down the servers, and archive the vmdks, since they're all
virtual. Second thought was to use Add/Remove Programs and uninstall Exchange
first, then just dump the VMs. But my concern is the schema changes, and the
Exchange security groups OU. If I uninstall through Add/Remove, does that last
one go out and clean up AD? Or is there something else that will need to be
done as well? Or, do I need to keep the AD stuff, since we're connecting to
the cloud solution, and managing all our mailboxes through ADUC and ADModify?
