Unblock a specific sender's email
I'm accessing my email using the classic Outlook app with a Microsoft 365 personal subscription on a Windows desktop PC. (I also have a business email using my employer's 365 business subscription i...
- The issue was finally resolved today after the sender’s tech support removed my email from a blacklist and added it to a whitelist.
With these actions done, it looks like the email hasn't been delivered at all;
With a support case at MSFT, an engineer can get you the information if the email was delivered or not.
Senders SMTP logs are not needed to find out if the email from a specific sender has arrived at your inbox (or not).
Sorry that I can't help you more!

Many thanks for trying to assist me with resolving this issue. It's appreciated.
I've been told by Microsoft support three times now, that the only way Microsoft can diagnose this issue, is for me to obtain SMTP logs from the sender for Microsoft to examine. The sender's tech support has confirmed for me twice, that they will not under any circumstances provide me with SMTP logs, which I can understand given that it's a financial institution with cybersecurity concerns. The sender's tech support did however confirm for me that their emails to my email address are in fact being sent by them, the emails are shown as having been successfully delivered, and that they are not receiving any indication whatsoever that their emails are being blocked.
After multiple attempts by me, and numerous Microsoft support cases opened and closed (without resolution) by Microsoft, including escalations, for three months now, no one at Microsoft support has ever said that they can tell me if the sender's email was delivered to Microsoft's server or is being blocked by Microsoft's server.
I can't help but imagine that if it were Bill Gates experiencing this issue, Microsoft would have fixed it in 3 minutes (without the sender's SMTP logs), and not bounced him around without a resolution for 3+ months.

- Then last option:
let the senders IT department open the MSFT case.
If they open the case, it will be allowed by security to upload the SMTP log. (MSFT should be a trusted party)- Upon checking again with the sender's tech support, they now say that all along they've known that somehow Microsoft has blacklisted the sender's email address. The sender's tech support has reopened its support case and they're looking into it.
- Glad to hear!
Would you mind marking my previous answer as the solution for you?
Hope the case at sender's side gets resolved soon!
- Thanks for this suggestion. I'll give that a try.
