hello, how can i unlock my account that have been blocked?, it says it can not send text message to my phone.

I sell lot of laptops, so I sign up many laptop with different account, and suddenly last laptop email get blocked. the problem is, that account contain the OHS 2021 that came with that Acer Laptop

 

Sending messages blocked

I am unable to send message from my Comcast account in Microsoft. It puts the messages in the outbox and says the sender (me) is blocked. I cannot retrieve them from the outbox. I can send messages directly from the comcast account on other devices
like phone and tablet. Suggestions?

 

Microsoft Account is Blocked

Okay first I enter the email and password to the login page. It reads that my account is blocked and i need to perform some security steps.

I added a phone number and ask to send the code through text.

Now no text came I tried the Call option still no call came.

Now eventually tried the above steps with a different no.

Guess what, results were same.
