If more than 24 hours have passed and the confirmation or code email has still not arrived, the most common reasons are:
- The email is being filtered or delayed
- The message may be in the junk/spam folder.
- The mailbox may be full or the mail provider may be delaying delivery.
- The sender address (for example, Microsoft account or Rewards notifications) may not be marked as a trusted/safe sender, so it gets filtered.
- The email address on the Microsoft account is not the one being checked
- Microsoft sends codes and confirmations only to the primary alias or to an email address that is configured as security info.
- If a different address is being checked than the one configured on the account, the email will not appear there.
- Automated protection or rate limits are blocking messages
- Excessive or repetitive requests for codes or reward-related emails can trigger temporary blocks where Microsoft stops sending verification codes or related messages for a period of time.
- Unusual activity or heavy compromised traffic from a region can also cause delays or temporary blocking of code delivery.
- Incorrect or outdated security info
- If the email address in the account’s security info is mistyped or outdated, the code or confirmation email will not reach the intended inbox.
If the email still has not arrived after checking spam/junk and confirming the correct email address is being used, the next steps are:
- Avoid repeatedly requesting new codes or resending too often, as this can extend rate limits or temporary blocks.
- If unable to receive verification codes at all, try another verification method (different email or phone) if one is configured.
- If sign-in or account access is affected, use the sign-in helper tool to diagnose issues.
- For persistent technical issues with delivery (for example, Rewards order emails not arriving even after 24 hours), contact Microsoft Support and describe the problem; support agents cannot send codes or change account details but can help with technical troubleshooting of services like Rewards.
