Hi Community
We setup a Flow using data from D365 and sending it to users via Send email.
Theissue we are facing is that for some users, the people picker is working, but for others it's not:

Does anyone have any suggestion or information on why it is working for some users and not others?
Is it the "Access Token missing or Malformed" and if so, any idea on how to fix?
Thanks in advance for your expertise
BEst regards
