Tagging based on 3rd party API
I'm not sure how to describe what I'm looking for so let me spell it out the best I can and maybe someone can point me in the right direction. Recently we've had some targeted spam/phishing attac...

Do you use the native external tagging feature: https://techcommunity.microsoft.com/t5/exchange-team-blog/native-external-sender-callouts-on-email-in-outlook/ba-p/2250098 ?

We do use the external tagging feature and are very happy with it. However, that only identifies when it's not a domain that we host for our company. I'm looking for some way to visually indicate we are receiving an email that is not verified in our CRM/Database.
I did review the "-AllowList" parameter from Set-ExternalInOutlook, which might have worked except the docs show "The maximum number of entries is 50, and the total size of all entries can't exceed one kilobyte. " I have well over 100,000 email addresses in our CRM. Even if I focus on non-free email domains (excluding yahoo, gmail, hotmail, etc), I have over 4,000 unique entries.
That's why I was hoping for some kind of API option so I wouldn't have to maintain a duplicate list of active email addresses on the Exchange system.
I'm open to any suggestions that might accomplish what I'm trying to do.

Hi RoisCannon,
If you are using Exchange online, then the combination of a transport rule and a Power Automate flow can do what you want. You can use this template as a base.
