Hi Kris!
Thanks for your reply.
The other user have the same mail box, he has signed in and accepted the different connectors when he started to use the app. There is no error message at all when trying to see flagged emails.
Furthermore, in the app one can also choose to look at calendar events, not yet completed tasks and planner plans/buckets/tasks. All of these things my colleague can access and see; it's only flagged mail that won't dance.
In the article you reference, they write:
This operation gets emails from a folder via graph apis. Please note that filtering related to these fields: To, Cc, To Or Cc, From, Importance, Fetch Only With Attachments, Subject Filter, is performed using first 250 items in a given mail folder. To avoid that limitation you can use 'Search Query' field.
Could that be the reason? What does the first 250 items mean? Does it sort the mails by date, ascending or descending? My colleague certainly has more than 250 mails in his inbox, so maybe that is why.
They recommend to use the seach query, but as I understand it, you cannot get flagged messages that way.
Looking forward to hear more from you.
