Hi @LevSupunS ,

I think you need to check Mail Sender details in Setup IFS connect window.

Check whether you have given correct authentication details.

Do you have MFA enabled on your outlook account?  if so you may need to refer to the instructions here

Hi @LevSupunS 

Check the Application message address line to ensure what’s the sender it’s using. Bit wired you are getting a google support link for a O365 mail sender, maybe this uses another mail sender connected to a google account?

Cheers!
