OnMicrosoft.com Office 365 Malicious and Spam Emails
OnMicrosoft.com Office 365 Malicious and Spam Emails

Spammers, scammers, or cyber-criminals are abusing Microsoft Office 365 by sending spam and malicious email messages from it, which they will use to trick their potential victims into sending them their money, personal and financial information, or clicking on links that will take them to malicious websites that will infect their computers with viruses, Trojan horse or other malware. Microsoft Office 365, often referred to as Microsoft 365 or Office 365, is a web-based version of Microsoft Office Suite.

How are Scammers Using Microsoft Office 365?

Spammers, scammers and cybercriminals are signing up for Office 365 accounts, creating email addresses and websites, and are using them to send spam and malicious email messages to their potential victims.

Here is an example:

The following fraudulent email message was sent to a potential victim; luckily she sent it to us to determine if it is legitimate:

Subject: Attn:This Is My Second Email, Please Respond
From: Ahmed Mohamed Ahmed01@lawoffice2013 .onmicrosoft.com

The cyber-criminals responsible for the fraudulent email created a website name or subdomain under “onmicrosoft.com” called “lawoffice2013”. The website or subdomain name looks like the following:”lawoffice2013.onmicrosoft.com

Then they created the email address “Ahmed01@ lawoffice2013.onmicrosoft.com” from the website or subdomain name. Once the email address has been created, they then send the spam and malicious email message above from it.

Cyber-crooks are using different website or subdomain names, so look out for suspicious email messages that are sent from email addresses ending with “onmicrosoft.com.” A lot of recipients of the spam and malicious email messages sent from Microsoft Office 365 or OnMicrosoft.com accounts created by scammers, cybercriminals or spammers, will think the email messages are legitimate because they are coming from “onmicrosoft.com,” which is owned and operated by Microsoft.

So, recipients of suspicious email messages that are sent from onmicrosoft.com or other email addresses, should never click on links in the suspicious emails to sign into their online accounts, should never send money or their personal information if they are asked to do so by suspicious emails, and should never respond to suspicious email messages.

I've received over 400 spams from and "......onmicrosoft.com email address in the past 2 months. After 50 of them I started sending spam notifications to
junk-office365.microsoft.com
abuse-microsoft.com
abuse-messaging.microsoft.com
abuse-frontbridge.com
Cert-Microsoft.com

The body of the notification contains this list of addresses.
Currently I've sent 139 notifications containing multiple spams to these email addresses. Microsoft seldom replies but when then do it's ALWAYS:
"....To report junk mail from Office 365 tenants, send an email to junk-office365.microsoft.com and include the junk mail as an attachment..."

What a bunch of IDIOTS! The very first email address in the list is junk-office365.microsoft.com!

I assume that they can't read English.

Received an email from noahsmith-t6usdy.onmicrosoft.com, the return address is noahsmith-redirecttheway.com, the email stated that I had compensation to claim due to a purchase I couldn't return or something. I have copied and pasted the full email in this for you guys to view and it may help someone else out there, who like me is broke and could easily have fallen for this, luckily I realised they don't mention the stores name at all, not only that I don't recall this ever happening where I had trouble returning an item let alone the last time I bought anything. Anyways here's the email...(I know it is but im hoping I'm not wrong)

NEW UPDATE: SUPPORT CASE #1684762866 DATED 22.05.2023

Dear Jodie ...,

I hope this message finds you well. I am reaching out regarding your support case from one year ago (22.05.2022), which, to our regret, remained unresolved due to a system malfunction. I was alerted to this oversight recently and immediately took the matter up with my superior, Richard.

Your initial complaint, lodged at our in-store service desk, involved an issue with a purchased item that you could not return or exchange. Unfortunately, the exact details of your case were also lost in the system error. This situation clearly contravenes our store policy, and we deeply regret any inconvenience this may have caused you.

To rectify this situation, we have determined to provide you with compensation. Given the duration of this issue, the compensation value will be significantly high. Please accept this as a token of our sincere apologies and as a testament to how much we value you as a customer.

To proceed, we need to confirm your email address: [email address removed]. Please respond to this email - your reply can be blank. As long as we receive your response, we can take the necessary steps to ensure you receive your rightful compensation.

Thank you for your understanding and cooperation.

Best regards,

I've today discovered that my wife has the following as an email address:
yubm.yubm-yubms.onmicrosoft.com. How do I know that this address has or is being used to scam us or others? What do we look for? How can we determine?
Thanks

by info

If your wife is not using it to scam others, that how you would know.

OnMicrosoft allows everyone to created accounts, it is what they do with the accounts is the problem.

You will have legitimate users creating OnMicrosoft accounts and using it to do their businesses. And, on the other hand, you will have cyber thieves creating accounts and using them to scam people, therefore, it recommended that you be cautious of suspicious emails from OnMicrosoft addresses.

I get onmicrosoft emails all the time, sometimes several per day (I got 3 today). I block each one from my Outlook and my network server. Unfortunately, this doesn't stop more from showing up, because each email is from a different individual. Does anyone know how they got my info and keep passing it around? Also, do you want me to forward each one I get to you? It would definitely clog up your server!
