Title: Flows containing office 365 triggers are failing to execute
User Impact: Flows containing office 365 triggers are failing to execute
More Info:
Not all flows are impacted by this issue, only flows using the “when an email arrives” trigger will be impacted.
Impacted flows can be found in the “checks” section of the flow maker portal.
Workaround:
If you have an impacted flow, disable and re-enable the flow in the maker portal to restore functionality.
Current Status: Following our investigation, we identified that this issue was caused by a previous flow connectors incident in which a recent deployment update to a portion of infrastructure responsible for routing traffic contained a misconfiguration that led to errors.
