I'm O365 Standard user, my flow has been sending email to others over a year without any problem. However, it doesn't work anymore since yesterday and I find out it is the sending email issue. I tried to switch to another O365 Standard account but no success with the error below. Power Automate license is assigned to each account I used in troubleshooting.
Test connection failed. Details: You are not authorized to perform this operation.

Does anyone have idea/workaround? Appreciate much!
