MS365 Internal Server Error - Send Mail

Hello

I'm using the below integration:

It was working fine but for the past 2-3 weeks I am getting this error:

I have tried so far:

1. Using a different MS365 account connection
2. Deleting all connections and re-adding to try again
3. Re-created the step fresh
4. Changing the Recipient email

None of the above have worked so far.

Any advice - is this a known issue with MS365?
