Not receiving emails

Hi

For 2 months I have been receiving progressively fewer emails. I have been through all the steps suggested (checking storage, rules, forwarding etc), and all these are OK. 

 

It's strange because some emails still get through, generally those from a private individual. The ones from big companies that I would normally receive eg phone supplier, utilities companies and reputable online retailers order confirmations or verification codes are not getting through. 

 

I've tried Microsoft support as I think it's a problem with their server for some reason blocking these emails, even though I've added them to my safe list, but they haven't been able to help.  They keep sending me to the sender team, which tell me to go back to the other team! I'm fairly sure it's not a problem with the senders side, as there are so many different companies affected, the common denominator is my email account as the problem.

Any ideas of a way I can fix this myself?

 

Thanks

    Because messages from individuals still arrive while several companies’ messages do not, the next useful evidence is a specific failed delivery, not another general check of storage or forwarding. Several affected senders do not by themselves prove where delivery is failing.

     

    First compare the mailbox directly in Outlook on the web with the desktop app. If the messages are missing in both, ask two affected companies for the exact sending time, recipient address, and delivery log or non-delivery report for a fresh test. An order-confirmation system saying “sent” is not proof that your mailbox accepted it.

     

    For a work or school Exchange Online mailbox, the administrator can use message trace to distinguish received, rejected, deferred, or delivered messages and inspect quarantine. For personal Outlook, give Support those concrete sender examples and SMTP responses. Safe-sender entries cannot by themselves diagnose upstream rejection, so a guaranteed local fix cannot be inferred yet.
