About 1,5 years ago we moved all the email database to MS365 and since then used online the cloud solution. This was and is not a hybrid connection between the on-premises Exchange server and MS365. Now I want to delete all mailboxes of on-premises server and uninstall it.
I am looking at this tutorial in this relation: https://techcommunity.microsoft.com/t5/exchange-team-blog/decommissioning-exchange-server-2013/ba-p/.... With some differences (e.g. disabling and deleting mailboxes instead of migrating them) this seems to be a good way. But another tutorial suggests that a single server should be left for management (though this tutorial considers a hybrid installation with 2016/2019 EX-srv): https://www.alitajran.com/remove-last-exchange-server/
My question is: How do I remove (or at least minimize) a no-more used Exchange Server 2013 installation und Windows Server 2012 R2.
Thank you in advance.
