Has anyone gone through the configuration of an IMAP connector to an Exchange online mailbox in a GCC high tenant? I've cobbled together the app registration information in Entra ID and plugged it into the IMAP integration credentials but the integration errors out.  Latest error being "Unable to authenticate with the specified integration. Error 'AUTHENTICATE failed.' There's no readily available means to pull up any logs for me to dig any deeper than this vague error.

There is a good document in the developer portal for this. 

What we are struggeling with is to understand WHAT username we should use to be able to fetch any email within the service principal which "own" e.g., 150 email accounts. We are only able to add a specific user account, but that limit us to one email address and not all.

If you figure that out. Please reach out to me at tobias.zackrisson@elkjop.no

Hi Tobias,

We are in the same boat here. Were you able to find a solution?

Hi Tobias,

FYI and for anyone reading this in the future this is what we ended up going with. There were some advantages to going with an IMAP integration but it was mostly for the ablity to fetch emails from a specific folder.

Thanks folks and apologies for the late reply, if you ended up using the Graph route, what specific app registration API perms did you specify?
