Sending a message at the right time is an art.
To program it is to cheat But its terribly effective.

And since timing often makes all the difference, you might as well choose it yourself.

Do you need to send an important message and want to make sure that the person you are talking to is willing to receive your message? Schedule the time to send your message.

Enter your message normally. Then, rightclick on the send button.
A scheduling window will open and you can choose the date and time when the message should be sent.

And then let Teams take care of it while you move on.
The message will leave even if Teams is closed or your computer is turned off.
Limitations:
  • This feature is accessible only with a Teams Pro license (not Teams Family).
  • You must have already conversed with the contact to be able to schedule a message.
  • You cant schedule an attachment to be sent
