Decommisioning our old (2010) exchange server

Hi All,

 

We currently have a 2010 exchange server that used to be our main email server, a while ago we changed it to being a hybrid server and now i have just removed the hybrid configuration using this guide:

Link 

The only purpose of this server currently is to run a sync daily to set the email attribute in Azure AD using the exchange shell and this command:

 

IMPORT-CSV Students.csv | FOREACH {Enable-RemoteMailbox $_.Username -RemoteRoutingAddress $_.Routing}

 

Would removing this server alter any of the current attributes, also if you know a way to do Enable-RemoteMailbox in a non exchange powershell terminal that would also be great,

 

Thank you

    The only supported method with Exchange 2010 is use Exchange tools to update attributes when you are syncing from AD to AAD. There is a way to remove Exchange on-premises for Exchange Server 2019 (details here: https://techcommunity.microsoft.com/t5/exchange-team-blog/removing-your-last-exchange-server-faq/ba-p/3455411)
    There is no option to enable remote mailboxes without having Exchange tools installed. Some more details on that scenario can be found here https://learn.microsoft.com/en-gb/Exchange/manage-hybrid-exchange-recipients-with-management-tools

      Hi Dan,

      Thank you for the help, we will migrate to exchange 2013, turn off the server and use Management tools to assign the attributes,
      Thank you for all the help

        The best path forward is to install an Exchange Server 2016 server, decom all the Exchange 2010 servers, then either install an Exchange 2019 server or if you don't want a server on-prem, do the schema update and AD prem from the latest Exchange 2019 CU ISO and shutdown the Exchange 2016 server as per the link in my original post

      Hi Dan,

      Thank you for that, would the best process be to upgrade through all the servers sequentially to exchange 2019 through 2013 and 2016 or to uninstall exchange 2010 and install 2019 directly,

      Thank you for your help
