Firewall blocking Microsoft Office 365 apps - Can't use Sharepoint or update apps and licenses

Hi,

 

I have just installed Total Protection, and so far not really happy. 

Firewall is jamming up every tentative connection. 

Browsers slowed down significantly and only work sometimes. Often a page returns a 'no internet' error, but after a few reloads it loads properly.

Microsoft Office 365 apps cannot communicate with the web - can't save files on OneDrive and SharePoint, and cannot download MS O265 software and license updates. 

The firewall has no hint as to which apps were blocked/granted access or a list of recent apps that tried to connect for me to just select the app and say "allow" - it's just not friendly ,and MSOffice apps should be known by the app already due to their popularity.

Turn off the firewall and voila - problems gone. But then again, why have a firewall?
