Using Exchange Activities with Outlook Online

Hi there,

My company recently migrated to using O365, Office Online and I am trying to use Exchange Activities but am facing quite a few complications. I am able to access the mailbox in outlook online, so I know it isn’t a permissions issue.

I am unsure of what format to provide for the Server and Username inputs. We have gotten various errors that aren’t the most helpful: “Unable to connect to the remote server” in most instances and “The response received from the service didn’t contain a valid XML” in one.

Any guidance would be greatly helpful, we’ve looked at other issues and haven’t found any resolutions that work for us.


The server Usually is “”, username should be “”, type your Domain name and password. in ExchangeVersion, usually latest is good for Office365
