MS Exchange Integration

Hi Community,
I was hoping if you could help me with integrating my MS Exchange account(not an Admin) with SnapLogic. I have followed the below two links for initial configurations but when I tried to add the account in the Event listener app, a new Microsoft webpage pops up with an error -
“AADSTS9002325: Proof Key for Code Exchange is required for cross-origin authorization code redemption.”

a new error
