    My company staff send message to the 2 companies which used the O365 e-mail system. The messages cannot delivered to user mailbox but I can find the message can be sent to O365 when I checked the server log in our e-mail system.

    I tried to find the information from the internet and some user suggested use the "Microsoft SNDS" to check our e-mail system IP address (IP reputation).

    Who know the link is provided by Microsoft because it require us to use Microsoft live account login first before acess the tools.

    Hi, definitely good to start with the global blacklists like Email Blacklist Check - IP Blacklist Check - See if your server is blacklisted (mxtoolbox.com) and after that check with Microsoft. Probably, if you have correct setup the SPF, DKIM, DMARC technologies, your e-mails will be more trusted even if IP address space can be marked risky. But definitely you can check if you received NDR message on Delist IP - Delist IP (office.com).

    If you are sending mail for marketing and promotion purpose, configure it on services like Mailchimp. These tools won't allow you affect your IP reputation. Check here for best Mailchimp alternatives as well.

    I'm curious about this too. If we're talking about emails here (and based on the original post, it's safe to say we are), I know that when an IP address is shared amongst a group of people, all of their reputations can affect each other's. Someone's IP reputation can be wiped clean by altering the domain's IP address. Maybe it'd be a good idea to invest in one of those email reputation tools? I wonder if OP tried that? It's been a while since they made their post, I'd be interested in hearing an update.

    Good afternoon, Albert. This is an interesting case and I hope that can some shed light on your predicament. If people have been suggesting you check your company's IP reputation, is there a chance that something could have been marked as spam? Maybe a series of emails? Please do not mistake me of accusing you or your colleagues of doing anything wrong. Systems are not people you know, and they can overlook things or take them out of context. I know there's a form online from Office 365 that lets you delist IP addresses. You could try that?

    This is the importance of an IT department in any company I wish to stay protected from underhanded tactics. It would be catastrophic if important data were to leak. I wonder if online casino businesses like Luckyslots also have that.

    Bounce of destination side of your mail / or mark it as spam or whatever could have a lot of suggestions:

    1. IP / mail-server is blacklisted / spam listed. You can verify it with spam check lists in Internet

    2. Destination side kick out all the messages not whitelisted. Usually you will have in return that your mail is not delivered and you should confirm your server under the link.

    3. No trust. Check with mail-tester.com There are a lot of factors so you can verify them all and setup if necessary

    4. The same problems with gmail general spam / untrust filters. If you have gmail address or your friend has send him the letter to check how it goes. Could be question to DKIM signature, DMARC record but it is only one suggestion

    5. If you do not have correspondence maybe not making active links with your first mail could help as well.

    Anyway start with mail-tester, you will get your rate immediately
