Hello Krispen

Thank you for posting your query on Microsoft Q&A platform.

What you’re describing closely aligns with a known scam pattern involving Azure alert emails.

In these cases, attackers first gain access to an Azure subscription and then deliberately configure alert rules to send notifications to external email addresses (such as yours). They subsequently trigger those alerts. While the emails are technically generated by Azure, the alert message content itself is authored by the attackers.

These emails typically include alarming language such as:

• references to a “Fraud Prevention System” or “Windows Defender,”
• warnings about large, suspicious charges,
• threats of account suspension, and
• a so‑called “Fraud Resolution” or “Support Hotline” phone number.

The objective is to pressure recipients into calling that number, where the scam continues.

Important guidance:

• Do not call any phone number mentioned in the email.
• Do not click any links included in the message.
• Simply delete the email.

It’s worth noting that these messages can appear convincing because they are sent from legitimate Microsoft email infrastructure. However, Microsoft does not include phone numbers or urgent call‑to‑action language like this in genuine Azure alert notifications.

The error message is about token validation in the Azure portal UI and isn’t covered in the provided Azure Monitor alerts troubleshooting guidance. The available guidance only covers:

• Not receiving expected alert notifications (email/SMS/voice/push)
• Unexpected content in alert notifications
• Alert processing rules not behaving as expected
• Actions not triggering or triggering multiple times

None of these address portal token validation failures or the specific error text shown when changing the date span in the Alerts blade.
