In-Depth Solutions Explained
1. Blocking Guests from Using Cameras in Teams
Goal: Stop guest users from turning on their cameras in Teams meetings.
Why the Proposed Solution Fails:
Changing Azure AD’s External collaboration settings only controls how guests sign in and what directory resources they can access. It does not manage meeting features in Teams.
Correct Approach:
Use Teams meeting policies:
- In the Teams admin center, go to Meeting policies.
- Create or edit a policy and set Allow video in meetings to Off.
- Assign that policy to guest users.
This ensures guests cannot use their cameras in meetings.
2. Auto-Creating Channel Folders in an Existing SharePoint Site
Goal: When you add a new channel to a team, automatically create a matching folder in the Sales SharePoint site’s document library.
Why the Proposed Solution Fails:
Creating a new team “From a group or team” always provisions a brand-new SharePoint site for that team. It doesn’t link channels to your existing Sales site.
Correct Approach:
Option A: Provision the team directly on the Sales site so channels map to its library.
Option B: Use PowerShell or the Graph API to attach an existing team to the Sales site’s group and site IDs before creating channels.
Option C: Manually add tabs in each channel that point to folders in the Sales site’s document library.
These methods ensure new channels get folders in the Sales site as required.
