Currently, only a handful of actions performed by Teams Administrators within the Teams Admin portal are audited and searchable within the Unified Audit logs. This should be extended to every action that can be performed within the portal.

Adding, amending and deleting Meeting Policies, Messaging Policies, all Voice options, assignment of policies to users are all unaudited; as are some major elements of the upgrading to Teams steps (such as coexistence modes).

Not knowing a) that these have changed, and b) who has changed them, what changes were made, and when they were made is a large security hole from a compliance perspective.

I would much rather have knowledge to changes of all items listed above, than whether someone has turned off Giphys across the org - which is one of the few currently audited items.
