O365 Action - Unable to get Message IDs

AETLE V6.4.7.3

I setup an O365 Connection and it tested ok.

However, same connection in an Action results in error 

Information    4/22/2026 9:45:37 PM    Selecting Mailbox:
Error    4/22/2026 9:45:37 PM    Failed to get list of email IDs: 

I believe I have setup all of the App Registration permissions - in fact more than needed



Critical I can get this sorted ASAP

I have followed the guide and set the permissions as per image. The client secret are used by another app that sends mail via the mailbox. So, the credentials are ok and the AETL Test Connection is always successful

Thanks
