This is an issue related to autoreply messages not being received by Gmail, Hotmail, and Yahoo email recipients. Xink rerouting cannot process Out-Of-Office emails that are directed to free email providers. To resolve this issue, a new Microsoft 365 transport rule must be created to exclude these emails.
Go to your Exchange Admin portal.
Click Mail Flow > Rules and Add a rule
Set the conditions with the below details. You can add more email domain as needed.
Use the header called 'x-xink-handled'
Enable the rule and set the priority to 0.
