Hi, For windows update we are having wsus server and pointed all the systems to get updates from wsus only.

But in the case of office 365 it is going to the internet to get updates and my internet link is getting fully utilised.

Kindly find the log screen shot which i have taken from my firewall.

Please help asap because it is critical issue for us.

Office365 cannot be updated with WSUS, this is not possible due to MSFT design.

You can reconfigure all client machines with Office365 to use an on-premises update location (server/share, or webserver), but you must manually download the new Office365 source (build) each month yourself.
