Account issue "Your organization's Microsoft Entra ID Free subscription has been disabled" and "We’ve disabled your Azure subscription"

Dear Microsoft Azure Support Team,

I am writing to seek clarification regarding the recent status change of my Azure account. Earlier today, I received two emails that left me confused:

• One email indicates that my account has been disabled, it looks like because of the end of my trial subscription.
• The other email mentions a suspension related to suspicious activity on the account.

As my trial subscription was indeed approaching its end, I initially assumed that the issue was simply the expiration of the trial period. However, the mention of suspicious activity raises concerns, and I would like to understand what exactly happened.

For the past two weeks, my account has only hosted a small, containerized application along with a small database. No unusual changes or deployments have taken place during this period of time, so I am unsure what may have triggered the suspicious activity alert.

Could you please clarify:

1. What exactly caused the account suspension?
2. Was it due to the trial period ending, or was it related to any specific activity flagged as suspicious?

Because If the issue is simply the trial expiration, I am happy to upgrade to a paid subscription immediately. However, if there was truly suspicious activity, I need to understand what occurred so I can address it appropriately.

Kind regards,
