Hi @v-yetonggu-msft ,
I successfully reconstructed the flow without encountering any issues.
The connection is also fine.
However, I'm contemplating two potential issues that might have contributed to the failure of the flow:
1. The email is sent on behalf of another (group) mail address (and the group mail address has no access to Power Automate)
2. During the flow execution, someone is editing the file.
Just want to prevent a recurrence of this situation in the future.
Thx
