Hello Community, how are you? I hope all well.





Has anyone had any impersonation problems when setting up an Exchange integration?


We did all the procedure listed in the KB:
https://integrations.siemplify.co/doc/exchange






The first time in an environment using the Community edition, it worked without problems, but when we went to bring this configuration to the final version, we got the impersonation error again.





If anyone can give me a hint, I would be very grateful. Thanks.

I had to contact support about this. They had me generate the OAuth/Refresh tokens needed for the integration using an "In Private / Incognito" browser window. This was not mentioned in the doc you link above.

Use of a fresh incognito session is necessary to force primary authentication to Azure AD as the service account that will generate the OAuth token and refresh token that will be used for impersonation. If you use an existing browser session, the OAuth token likely will be linked to your personal Azure AD account, and impersonation then will fail because it is unlikely that your personal account is trusted for impersonation.
