We need to block Excel macros from Internet sources. I have enabled the following settings in GPO Excel trust Center settings:
Block macros from office files from the Internet = Enabled
Allow trusted locations on the network = Disabled
Turn off trusted documents on the network = Enabled
The result of this is that an internet macro wont open from either c: or the users Onedrive, BUT any file that is shared over MS Teams will always open and it never has the banner at the top 'be careful about files from the Internet" and the macros execute unhindered always.
How can I make Teams either not be inherently trusted or recognise the file was sourced from the Internet correctly.
Thanks
