    Hi Soham,

    I can understand how annoying it is to get blocked right when you're trying to set up Teams for work.

    To help pin down the exact cause, could you please share a few quick details?

    • Are you trying to create a free personal Microsoft account with your work email, or sign up for a Teams for Business subscription?
    • Are you using a VPN, proxy, or a shared corporate IP network while attempting the signup?
    • Has your company's IT admin already managed or assigned Microsoft 365 licenses to your domain?

    Meanwhile you can try some workarounds that may help you to fix the issue:

    • Use Incognito / Private Browsing: Open a fresh Incognito or InPrivate window or switch to a mobile network hotspot just to bypass IP-based automated security flags.
    • Try Sign-In Instead of Sign-Up: If your company already uses Microsoft 365, your work email might already have an account provisioned. Try signing in directly at teams.microsoft.com or login.microsoftonline.com instead of registering a new personal account.
    • Sign Up via Teams for Free Page: If you are setting up Teams Free (classic/work), use the official Microsoft Teams Signup Page rather than standard account creation.
    • Contact Your IT Administrator: If your company owns the domain, your IT department may restrict employees from self-registering accounts outside their managed tenant.
