Updating the exchange server is not permitted

Error message: Updating the Exchange endpoint is not permitted. Please contact Nylas support to do so.

Explanation: This error message happens because you've previously signed up for a service backed by the Nylas Cloud APIs while specifying a different Exchange server endpoint / host name.

For security reasons, subsequent authorizations you must use the same Exchange server endpoint as before.

If you are certain you are using the correct endpoint per your email administrator's instructions, please contact us so we may further assist.
