MS account verification email not coming through in any folder when trying to link MS account to Halo.

This is usually caused by a temporary verification block, the code going to the wrong verification address, mailbox filtering, or a sign-in/session conflict.

Try these steps in order:

1. Stop requesting new codes repeatedly Excessive or repetitive requests can trigger a temporary block where Microsoft will not send codes.
2. Check the correct mailbox Verification codes sent by email can only be sent to the primary alias or another email added as a sign-in verification method.
3. Check Junk/Spam and trust the sender Valid verification emails come from @accountprotection.microsoft.com. Check junk folders and mark that sender as trusted.
4. If the verification email is another Microsoft address such as @outlook.com, @hotmail.com, @live.com, or @msn.com, use privacy/InPrivate mode:
   • In one private window, stay signed in to the account that is requesting the code.
   • Open a second private window.
   • Sign in to the alternate Microsoft email account there.
   • Copy the code from that mailbox back to the first window. This avoids the browser signing out one account while accessing the other.
5. Try another verification method If another method is available on the account, use it instead of email.
6. Try another network Switch between Wi‑Fi and cellular data, or use a different Wi‑Fi network.
7. Wait before trying again If the account or verification flow was flagged for unusual activity, waiting can clear the block. Guidance is to wait a day, and if needed longer, up to 1 week. Repeated attempts can reset the time lock.
8. Verify or replace security info if accessible On the Security basics page, select Update info, then choose a method that works, or choose I don't have any of these to replace the security info.
9. Use Microsoft sign-in troubleshooting if still blocked If sign-in still fails, use the Microsoft sign-in helper.

Important limits:

• Microsoft support agents cannot send verification codes or change account details.
• If the issue is a temporary security block, the code may not arrive until the block clears.
