MSTeams Groups in outlook with macros disabled

Hi All,

As part of security hardening, we have disabled macros in MS Office for all bar a few users. The problem we have is that team groups that users have that appear in outlook, when they click on the group in outlook they get an error message

"The function you are attempting to run contains macros or content that requires macro language support........."

After the user clicks ok they can see message int he group no issues but we would like to get rid of that error message. I'm not sure what "Macro" is trying to be preformed. 

Any ideas ?
