I'm unable to receive any mail regarding OTP from other service

Hello,

This is not an isolated incident. I have experienced this issue multiple times. Whenever I request a one-time password (OTP) from various services, I often don't receive the email at all. In some cases, the OTP arrives after 24 hours, by which time it has already expired. On other occasions, it never arrives.

Currently, I have been waiting for more than 15 hours for an OTP from a service, but I still haven't received it.

For your information, I have already checked my Junk folder and all other email folders, but there is no sign of the missing OTP emails.

What's particularly concerning is that I receive OTP emails from the exact same services without any issues when using my iCloud email address. This makes me believe the problem is specifically related to Outlook.

Could you please investigate why Outlook repeatedly delays or fails to deliver these emails? I would also appreciate your guidance on how to resolve this issue permanently.

I rely on my Outlook email address for important accounts, so receiving OTP emails reliably and on time is essential.

I look forward to your assistance.

    Hi @Partho Roy

    I’m sorry that your OTP emails are repeatedly delayed or never delivered, especially when you need them to access important accounts.

    Since you have already checked all folders, please review Settings > Mail > Junk email, Rules, and Forwarding in Outlook.com to ensure the sender is not blocked and the messages are not being redirected. If possible, add the relevant sender address or domain to Safe senders and domains.

    Please also contact the service sending the OTP and ask them to check their delivery logs for any rejection or delay response from Outlook.com. This information can help determine whether the message was sent successfully or blocked before reaching your mailbox.

    If this affects multiple services and continues after checking these settings, please contact Outlook.com Support and provide the sender domains, the dates and times when the OTPs were requested, and examples of messages that arrived late.

    Please note that this is a user-to-user support forum. We do not have access to mailbox delivery logs or back-end systems to investigate the cause directly.
