Share a Folder in a Channel to Outside Users

Navigate to the Files tab inside the Teams channel
Click on the New icon located on the ribbon directly above the file directory and create a folder
1. Enter the name of the folder
Click on the folder you just created
On the same ribbon where the New icon was located, click on Open in SharePoint. This will open a window in your internet browser
The page that opens in you browser will be very similar to the one seen in Teams. On the ribbon located above the file directory, click on Share
In Send Link pop-up, you can enter the name or email address of the individual(s) you wish to share the folder with. Once entered, press Send to share the folder
1. Note - By sharing the folder with the individual(s), the shared user will only have access to the folder within the Teams Files tab and not the Teams messaging channel
