Enable file sharing and calling to External Persons in Teams

Hi,

Give this a try.

Cheers

✅ Part 1: Enable File Sharing with External Teams Users

🔹 Step 1: Enable External Access in Microsoft Teams Admin Center

Go to Microsoft Teams Admin Center

In the left-hand menu, go to Users > External access.

Set “Users can communicate with other Teams users” to On.

Optionally, allow or block specific domains using “Add a domain”.

Click Save.

🔹 Step 2: Enable External Sharing in SharePoint/OneDrive Admin

Go to the Microsoft 365 Admin Center: https://admin.microsoft.com

In the left menu, select Admin centers > SharePoint.

In SharePoint Admin Center, go to Policies > Sharing.

Under External Sharing, set SharePoint and OneDrive to "New and existing guests" (or “Anyone” if you prefer anonymous access).

Click Save.

🔹 Step 3: Adjust OneDrive & Team Site Permissions (if needed)

In SharePoint Admin Center, you can also configure sharing settings for individual sites (e.g., the Teams-connected SharePoint site).

Go to Sites > Active sites, click the site linked to your team, and adjust its sharing settings.

✅ Part 2: Enable Calling with External Teams Users

🔹 Step 1: Enable External Access (Same as above)

This setting allows users in your org to chat and call with users in other Teams tenants.

Again, go to Teams Admin Center

Navigate to Users > External access

Make sure “Users can communicate with other Teams users” is On

You can also allow or block specific domains
