Hi all,

We have an ASR rule to block executable content from email client and webmail.

Unfortunately, this rule blocks "Metting options" in a Teams meeting.

Is there a possibility of creating an exception? A path-rule exception doesn't seem to be an option.

    Hello there,

    If this is the first time you are deploying ASR please check the prerequisites.

    There are four steps to troubleshooting these problems:

    Confirm prerequisites
    Use audit mode to test the rule
    Add exclusions for the specified rule (for false positives)
    Submit support logs
