Office 365 emails have blocked me
Hi, the first thing i would recommend you check is that your domain has not ended up on a blocklist.
You can use this tool to check - https://www.spamhaus.org/lookup/ and if you have been blocked you can complete a removal request.
That is a good start at least. It may be then that you are hitting some of the Exchange Online Limits that are in place. Please take a look at this - https://docs.microsoft.com/en-us/office365/servicedescriptions/exchange-online-service-description/exchange-online-limits?redirectedfrom=MSDN#receiving-and-sending-limits and see if you mat be hitting any of the send limits.
- I think I am hitting limit because I'm sending over 30 emails a min at times. Do you have any add-ons / software that I can use to send bulk mail? I used to work for a company that uses Microsoft office emails but they could send thousands of emails with no issue. Also, how can I unblock my emails so I can start using again?
Fouzy1545 Hello, it sound as if your previous company used distribution groups. As for bulk email it violates the Office 365 terms of service.
Official quote.
"Exchange Online customers who have to send legitimate bulk commercial email (for example, customer newsletters) should use third-party providers that specialize in these services."
