Hi Roland

I had not tried it before, but I have set it up based on our own setup.

We do not have an OnPrem exchange server, we use the MSGraph version which is part of Azure Active Directory.

I already have an app with Application type rights. This meant that I was able to use the CLIENT grant type, which allowed me to gain access.

I don’t know if you attempted this in the new version or an older one, but I used the following fields.

• I set the Auth Scheme field to OAuth
• I set the Schema field to MSGraph as it was suggested here as it was for the online version.
• Because I use the CLIENT Grant Type, I needed to add our Tenant ID to the Azure Tenant field.
• I set the Initiate OAuth field to GETANDREFRESH, but having it set to REFRESH also works.
• I added the Client ID of my app to the OAuth Client ID field.
• I added the Client Secret of my app to the OAuth Client Secret field.
• I set the OAuth Grant Type to CLIENT. I could also keep it as the default CODE value, but I would need to have specific rights on my user to be allowed to use that option.

That was essentially what I did and it worked for me.

If you are using a OnPremise server, you will need to specify a server name and user+password to gain access.

Hi @roland.peeters were you able to connect to the exchange server using the Cdata connector? If so please help us by marking the best answer above. Please let us know if you have any follow up questions
