Office 365 emails have blocked me
I have tried contacting Microsoft twice, first time I was put on hold then the guy hungup the second time I called I was told I'll get a call back but never did so this is the only place I can go ATM....
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.
- Just checked and I have not been blacklisted.
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?
