I encountered MS 365 connection error (per screenshot) during an auto scheduled refresh today. This auto schedule has been working fine daily for a week without any connection error. What could be the possible causes? Thanks.
Question
Action flow Microsoft 365 module error: Failed to verify connection. No refresh token specified.
Hi Chen ,
- Can you please check in case there was any change in password recently .
- As an alternative solution - can you please logout from the email account you are logged in and then please again log in
- OR , Please create a new connection with the same email account and use the new connection reference.
Hope this helps!
Regards
Ayan
