Received email notification From Microsoft about Deactivating Outlook Mail on 10/15/26

This is most likely a phishing scam, especially if the sender addresses look suspicious.

Signs that match phishing in this case:

• Messages use urgency or fear, such as warning that the mailbox will be deactivated or data will be deleted.
• The sender address does not use an official Microsoft support domain.
• The message tries to push immediate action through links or attachments.

Microsoft support states that legitimate support emails use these domains:

• microsoft.com
• microsoftsupport.com
• mail.support.microsoft.com
• office365support.com
• techsupport.microsoft.com

If the email came from a different domain, it is likely phishing.

What to do:

1. Do not reply.
2. Do not click links or open attachments.
3. In Outlook, check for warning indicators such as an unverified sender (? in the sender image), a via tag, or yellow/red safety bars.
4. If signing in is necessary, go directly to Outlook.com and verify the address bar includes login.live.com before entering a password.
5. Mark the message as junk or phishing and delete it.
6. If there is concern the account was already accessed, follow the Outlook.com account recovery guidance.

Outlook also shows signs of suspicious mail:

• A ? in the sender image can mean the sender could not be verified.
• A via tag can indicate the actual sending domain differs from the displayed From address.
• A red safety bar means Outlook.com blocked something unsafe and the message should not be opened.
