How to keep my emails and messages private in Teams
You might want to use MailClark to receive your personal emails and/or tweets in Microsoft Teams and keep them private.
MailClark only works in channels—not in private chat. Besides, third-party apps like MailClark cannot be added to private channels although this might change in a near future.
In the meantime, you can always set up a private team dedicated to your emails and messages.
