The Activities is located in Window > Activities, In Activities you can see the progression of your emails that were performing for Airmail such as syncing, downloading messages etc.

In the screenshot above it shows you the list of account that is successfully connected and in action, So whenever your email is tasking for Airmail you can see the rest of the account in Activities window but it doesn’t show the progression in percentage just the performing tasks. 

Do not get confused with “Operations”, The operations function allows you to redo and revert tasks that were already performed. However in the Activities you can see the progressions only.
