Configure Outlook 365 App with 2010 Exchange Server

I am currently testing Office 365 business and want to use the Outlook application on my laptop to access our company exchange server which is 2010 and externally hosted.

I am using onmicrosoft.com as my domain at the moment.

Can someone help as to how I would configure either Exchange/Outlook 365 to work with Exchange Server 2010

Thank you

Hi, thats not actually supported:
https://docs.microsoft.com/en-us/exchange/plan-and-deploy/supportability-matrix?view=exchserver-2019#clients

You wouldnt use onmicrosoft.com however to connect to an Exchange 2010 server, thats used for Microsoft 365 domains. You would use your "real" domain, not the onmicrosoft.com one.

You should probably contact the admin for your company, but generally you enter your primary EMAIL address and Outlook automatically configures it.

Hi @JamesB-4129

Yes, like Andy said above, Microsoft 365 Apps is not supported for Exchange 2010 server.

In addition, Exchange 2010 has reached its end of support, I would suggest you migrate to O365 or Exchange 2016. And the Exchange Deployment Assistant will be helpful to perform the migration.

You could at the following lines to C:\Windows\System32\drivers\etc\hosts

10.0.0.65 mail.yourdomain.tld
10.0.0.65 autodiscover.yourdomain.tld

change 10.0.0.65 with the IP of your Exchange server.
change yourdomain.tld with your domain.

Consider this as a quick-fix, upgrade ASAP to a supported Exchange version.
