Decommision Exchange 2007 (SBS 2008)

Question

Hello,

SBS 2008/Exchange 2007
Mailboxes are migrated to O365(no hybrid).
SBS 2008 roles (AD,ADCS,DHCP,DNS,WSUS...) are not migrated to another server.Only mailboxes are migrated.
Is it supported to decomission Exchange 2007 from SBS 2008?

This article mention that decommissioning Exchange from SBS is not supported until SBS is ready for decommisioning.

https://www.mattwall.co.uk/2018/01/12/Decomissioning-Exchange-on-SBS-2011.html

"This is generally not recommended as it can easily break some of the functionality of the SBS."

"It is generally considered best practice to simply disable all the Exchange services until the SBS is fully decommissioned and I would highly recommend this if at all possible.

(As stated the following is not supported or recommended so proceed at your own risk! I HIGHLY recommend taking a full restorable backup before continuing)
"

Can I found official Microsoft statement it is not supported or recommended

Thank you

Hi @Andy

Yes, agree with Andy, you can Uninstall the Exchange 2007 from SBS 2011 if you have migrated the exchange on-premises to O365. Once you make sure the mail flow is working fine with O365, you can then decide to remove the exchange from SBS.

First try to uninstall the Exchange from programs and features.

You may see the warnings on the Uninstallation wizard. It will roughly include following steps to follow.

1.Empty the Mailbox databases and Public folder databases folders from their respective locations on the server.
2.Remove the Databases entries from Configuration partition in the ADSIedit.
3.Disable or remove the connectors in the Exchange. Such as Send and receive connectors.
4.if you get error for any process relevant to exchange, kill that process and continue.
And that will remove the Exchange roles and uninstall exchange.

Or you could refer to SBS Server: Remove / Uninstall Exchange
