Query about creating topics in a category using email

Hi all,

We are looking to replace our mailman mailing lists with a solution using Discourse.

Sending an email to create a topic in a category looks like it would be a good solution for us:

We are also hoping to use this OAuth2 plugin to authenticate to our ‘Reply To’ email on Microsoft 365:

I was just wondering if anyone had any experience using this combination of features?

We are hoping to use 1 email mailbox on Microsoft365. For the custom incoming email addresses would we be able to set up aliases for the Microsoft365 mailbox to accommodate the various custom incoming email addresses needed for the categories?

Any knowledge or insight would be greatly appreciated, thanks in advance!
