Android phonce cannot edit Calendar events

Dear Experts,

I have a client using Office 365 but recently his calendar events cannot be edited.  The edit button is replaced with a trash bin.

We tested on two other user accounts, they can edit the calendar invite.

Is there a setting that is different in the user settings of Office 365 or Outlook 2016?

We found that the issue was with the exchange where it somehow created a secondary email address. We then change the SMTP back to the Primary Email Address and my client was able to edit the calendar where he is the organiser only.
