Hello **** Mark
It appears that you are experiencing an issue where guest users cannot see the “Files” tab in Microsoft Teams when using the browser version.
Please note when guests access Teams through a web browser, they might encounter limitations compared to using the Teams desktop
or mobile app. One such limitation is the visibility of certain tabs, including the “Files” tab.
If guests do not have the Teams app installed, they may only see the “Posts” tab and not the “Files” tab in the channel.
However, there is a work around. To make shared files accessible to guests via the browser, you can create a custom
tab using the “Website” app. Here’s how:
1.Click on the “+” icon at the top of the channel.
2.Select “Website” from the list of apps (you can use the search bar to find it quickly).
3.Give your tab a name (e.g., “Shared Files”) and paste the SharePoint link to your folder.
4.Click “Save.”
5.Now, this tab will be visible to all team members, including guests, who can access it anytime they want
Remember that guests who have the Teams app installed will have a more comprehensive experience, but creating a custom tab with the
“Website” app should help address the browser-specific limitation for guests.
If you need any further assistance, please feel free to post back. we will be happy to assist you.
Sincerely,
Bertrand
