π‘οΈπ§βπΌππβοΈGroup - Unsigned Macros Allowed users
What this group is forβ
This is a static assigned user group that carves an exception out of the macro signing baseline for Microsoft 365 Apps.
It works only as a pair with:
- βοΈπͺπ§βπΌCP - Microsoft 365 Apps - Macro Signing: the baseline this group is excluded from.
- βοΈπͺπ§βπΌπCP - Microsoft 365 Apps - Macro Signing - Exemption: the inverse policy assigned to this group, which restores prompting behaviour.
Both assignments are required. The baseline writes Trust Center values into HKCU\Software\Policies\Microsoft\Office\16.0\<app>\security, and those values stay written when a user leaves the profile's scope.
This is a user group, not a device group, because Office Trust Center settings live in the user hive. An exempted user carries the weakened Trust Center to every machine they sign in to, shared devices included.

β οΈ Governanceβ
This group hands a user back the Enable Content button, which is the exact button two decades of malware has been built around. Treat membership as temporary by default:
- A named file or application, not a job title or a department.
- A named approver on the customer side.
- An end date, and a plan for what happens before it: signing the macro, replacing it, or retiring it.
- A quarterly review that actually removes people.
Good reason: a month-end workbook nobody can sign until the original author's certificate is replaced. Bad reason: "finance uses a lot of spreadsheets." The right destination for almost every member of this group is a signed macro and a removal from the group, not permanent residence.
