2️⃣ Solution 2: Verify Exchange Room Permissions

Ensure your account has "Room Calendar" delegate access:

1. In Outlook, go to File > Account Settings > Delegate Access > Room Calendar.
2. Add your account with Reviewer or higher permissions.
3. Wait 15-30 minutes for sync, then refresh Teams.

Pro Tip: Admins, check via Microsoft 365 Admin Center for bulk room policies.

3️⃣ Solution 3: Update Teams & Reset Network

Grab the latest Teams version from the official site:

• Windows/Mac: Help > Check for Updates.
• Reset network: ipconfig /flushdns (Windows) or flush DNS on Mac.

If corporate firewall blocks, contact IT—ports 443 and 80 must be open for Exchange sync.

For stubborn cases:

1. Uninstall via Settings > Apps.
2. Download fresh installer from teams.microsoft.com.
3. Run as admin and select "Teams for work or school."
