I would like to request all of your help.
I have a problem with skype for business that our network users cannot connect to Skype for Business according to block by Mikrotik. So how can i configure to allow access to skype for business in Mikrotik.
Thank you
Maybe that will help

It would likely just work with the default configuration, and you do not show us what configuration you actually use, so difficult to tell.
