I have created a new outlook.com email address and it is linked to my 365 account, however it keeps blocking emails sent my me to my group of friends. I can send individual emails successfully.

I understand that they are trying to stop spam emails but how do i convince Microsoft to allow them.

When logging into my 365 account they send pass codes to my new address so they must know it's genuine. I am a treasurer of a society and need to send block emails. How do I solve this problem? It is not convenient to only send to groups of 5 or 6 it takes too long.

Microsoft doesn't seem to have or want a customer service team and am just referred to use this. The only customer service they seem to have is taking money from me then stopping me from using their products

    I've got an answer, but you're not going to like it.

    There are hard limits on how many people you can put on a single email and how many emails you can send per day. But you aren't anywhere close to these values.
    https://support.microsoft.com/en-us/outlook/sending-limits-in-outlook-com

    What you have run into are the "variable" limits. This is based on such factors as how old your outlook.com account is, what your past sending history is, and other parameters that Microsoft does not make public so the Spammers can't figure out a way around them.

    There is no single document from Microsoft on how to increase your "Reputation" so you can get closer to the hard limits. All I can suggest is that you prompt your favorite AI with something like this and try some of the suggestions.

    How can I increase the Reputation of my outlook.com account so I can send more emails per day?

    Don't expect miracles. Whenever I first bring a new outlook.com account on-line, it can take weeks before I don't run into some kind of sending limit, or all of my emails are automatically marked as Spam by every email hosting provider. (Including Microsoft).
