Issue Status: RESOLVED
Microsoft reference: MB986913
Issue Description: We are aware of an issue which is currently preventing some end users from accessing Microsoft Bookings calendars. Users may be presented with a warning page stating that the website is classified as malicious.
Final Update: 23/01/2025 09:15:00 AM – Microsoft have confirmed that the issue is now fixed. Microsoft identified an issue in which a third-party anti-spam service was falsely flagging organization’s IP addresses as potentially malicious, resulting in the IP address being added to a block list. Microsoft have added the affected IP addresses to an allow list to bypass the block from the third party anti-spam service, and confirmed through monitoring service telemetry that the impact has been remediated.
We apologise for any inconvenience caused whilst we worked to resolve this issue.
