If you use email notifications with response links to notify users, it's possible that malware protection (antivirus) software can affect response processing by xMatters.
This is because some malware protection software, such as Proofpoint, scans incoming email and automatically follows links found in the email content (and sometimes even overwrites the links). So, by the time a user clicks on their response choice from the email notification, the actual URL of that response may have been invoked several times.
What can you do?
Consult with your malware protection software vendor about how to configure your settings to avoid incorrect responses to xMatters notifications.
