Nomadesk emails with links can get blocked by Microsoft

Our links are sometimes flagged as "unsafe" due to a feature called "URL Detonation Reputation." This is a Microsoft feature that has caused some frustration, as evidenced by this community post: https://techcommunity.microsoft.com/t5/exchange/url-detonation-reputation-how-do-you -like-it/m-p/3944541
