Dear Support,

We have just finished a complete migration from Exchange 2013 to Office 365 Exchange Plan.

Our on-premise Exchange 2013 has been powered off for the last three weeks and we are now ready to proceed and remove and delete Exchange 2013 from our Windows 2012r2 domain.

Our domain is as follows :

Windows 2012r2 ( 2 x Domain Controllers)

Exchange 2013 ( 1 Server with around 80 mailboxes and some PF)

I cant seem to find an official Microsoft guide on "How to remove Exchange 2013 completely" 

Once again my exchange server still has all of its database etc, we have simply power it off and are ready to uninstall it, I just a MS Guide to follow, I've seen loads of various posts but no official instructions.

Cheers 

Setup.exe /mode:Uninstall /IAcceptExchangeServerLicenseTerms

This command completely removes Exchange 2013 from the server and removes this server's Exchange configuration from Active Directory.

Hi Roger,

Thank you for your question.

By you state, Exchange 2013 has been powered off for the last three weeks, so we think message flow and PF have no problem on office 365. We could refer to the following link to remove Exchange 2013:

Notice: This is a link which is about Exchange 2010, but it also apply to Exchange 2013.

If there are any questions regarding this issue, please be free to let me know. 

Best Regard,

Jim
