Learn more about how we're making external collaboration setup easier for SMBs

We know that collaboration with customers, vendors, and partners outside of your small or medium business is critical to your success. We also know that many SMBs have limited IT admin resources, and setup can be a challenge.

To make external collaboration setup in Microsoft Teams easier for your SMB, we have introduced a new overview page in Teams admin center that consolidates settings into a single view and have simplified how we describe the settings you can apply.

From the new settings, you can select from pre-configured modes that quickly set smart defaults that are right for your business.

  • If your business is open to external collab across chats, calls, meetings, and teams and channels, you can select Open mode to quickly get setup
  • If your business is more conservative, you can select Controlled to align to pre-existing external collab defaults
  • If you want full control of what is enabled and disabled for your business, you can always select Custom as well

We're looking forward to hearing your feedback about the new settings experience.
