Problem with authentication via object POP3/SMTP and Microsoft365-outlook

[JoannaMatecka]

Hi,

We are trying to receive e-mails from shared mailboxes in two robots. At the beginning we register App and configured everything as it is described in the guide also POP3 feature is enabled in both mailboxes which we want to use. We tried 2 different approaches:
1. Using object Email - POP3/SMTP with authentication via MSAL.net. We are able to receive access token and later we provide it to POP3/SMTP configure action:

After this step we want to receive list of emails and we are not able to due to following error:

2.Using object Microsoft 365 - Outlook we go through the authentication action providing app id, tenant id and secret. We use action 'List mail on folder' again with no luck 😞 
Following error appears:

HTTP request which we want to send is:

Will you be able to help us?

Best regards,
Joanna

Your issue may be because of the Deprecation of Basic authentication in Exchange Online.

Our most recent version of "MS Outlook VBO" (LINK HERE)supports Shared Mailboxes, or you can use the" Function for Microsoft 365 - Outlook" (Link Here).
