Distribution List to Teams Channels not delivering all messages
Hi LeonPavesic
Thanks for your response - I have tried three recommended ways of creating distribution lists to send to Teams channels but get the same results with each option - out of twenty addresses only a maximum of sixteen will get delivered.
I have no rules on the Distribution list, I have a Rule that adds a disclaimer if the email address is from a company Teams address, but this stops processing other rules if the conditions are met.
Teams allows emails to be sent to channels, if I send a message to each channel individually using the entry used in the distribution list then all are delivered.
Very stumped on this as I would not consider twenty to be a number that would be caught in any spam filters - any further suggestions welcome as Microsoft support just ask for my availability - ignore it then ask for it again - beyond frustrated now.
Thanks

Personally I would use a completely different approach. The mechanism to send emails to channels isn't very easy to manage, it has it's own email filtering with a default configuration you can't configure..
My recommendation would be to use Shared Channels, so you have one overall Team and share a channel from there with each of your individual Teams. Your users will see it as a channel among their existing channels, but they all see the same content. Post your announcements in there, mention @everyone and they will all get notified. They can even react or reply to the messages for all to see.
Other than that there is an extension called Company Communicator that Microsoft provide but would need some Azure resources to deploy. It allows you to author a message and deliver it to users as a personal message to each of them.
