Is it time for a coffee break? (Correct answer: Yes!)
Check to see if your coffee break buddy is free.
In the main Skype for Business window, scroll through your list of contacts and locate your coffee buddy. (If they aren't in your contacts list yet, click the Previous button on this page to go back to the last module, Add a contact.)
Take a look at their round profile picture. If there's a green dot in the lower right of their picture, then they are most likely at their computer and quite possibly free to join you for coffee.
IM them to ask if they'd like to take a coffee break.
Hover over their picture to access the quick menu.
Click the IM button.
In the IM window, type "Hey, have time for some coffee?"
Note: Don't drink coffee? Substitute a beverage of your choice.
