Sharing Stream (on SharePoint) video link in Teams still redirects to original SharePoint site and prompts external users for access

Question

Sharing Stream (on SharePoint) video link in Teams still redirects to original SharePoint site and prompts external users for access

Mohamed Irsyadudin 20

Hi,

I would like to clarify expected behaviour when sharing videos via Microsoft Teams and SharePoint.

Scenario:

A video file is stored in SharePoint Site A.
The video link (URL) is posted in a Microsoft Teams channel, which is backed by SharePoint Site B.
External (guest) users are members of the Teams channel and have access to SharePoint Site B.
When these users click the video link from Teams, they are redirected to SharePoint Site A and are prompted to request access.

Additional observation:

Even when the link is added to a page or location in SharePoint Site B, the video playback still redirects users to Site A.
The video itself is not uploaded or copied to Site B; only the video link is shared.

Question:

If a Stream (on SharePoint) video is currently stored in SharePoint Site A and shared to external users via a Teams channel (Site B), causing them to request access, will downloading the video and uploading it directly to Site B allow those external users to watch the video without additional access requests?

Is this the recommended approach for external sharing?

Goal: Allow external users who already have access to the Teams channel to play the video without additional access requests.

Hi @Mohamed Irsyadudin,

Thank you for posting your question in the Microsoft Q&A forum.

Regarding your question about the changing the file save location:

If a Stream (on SharePoint) video is currently stored in SharePoint Site A and shared to external users via a Teams channel (Site B), causing them to request access, will downloading the video and uploading it directly to Site B allow those external users to watch the video without additional access requests?

I want to confirm that yes after downloading the video and uploading it directly to Site B will allow external users who are already members of the Teams channel (Site B) to access and watch the video without needing to request additional permissions.

After moving the video to Site B, please follow these steps when sharing the link:

Select Share on the video file.
Click Link settings.
Change the link type to “People you choose.”
Set the permission level to “Can view.”
Click Apply.
After that choose "apply", then add the "Site B member" to the list people you choose
Copy the link and share it in the Teams channel.

Note: The video must be stored in Site B for this to work. As long as the file remains in Site A, external users who do not have permission to Site A will continue to be prompted to request access even if the link is shared in a Teams channel associated with Site B.

Thank you again for your time and understanding. While my initial response may not resolve the issue immediately, I’d like to gather more details about your situation so I can assist you more effectively.

I really appreciate your patience, and I’m here to help. Looking forward to your response.

Wishing you and your family a prosperous New Year.

Hi Henry,

Thanks for the detailed explanation, this helps a lot. Just to clarify, this Teams channel has over 500 members. When managing access to the video stored in Site B, is there a recommended way to grant access at a group or channel level, or would access need to be explicitly assigned (for example, via “People in Contoso” vs individual users)?

I want to make sure we follow the recommended approach before proceeding. Thanks.

Hi @Mohamed Irsyadudin,

Great question, this is an important point to clarify before rolling this out at scale

Recommended approach for granting access at scale (500+ members)

When the video is stored in SharePoint Site B, you do not need to assign access to each user individually.

Instead, the recommended and scalable approach is:

Use “People you choose” + the SharePoint site group

Select Share on the video file

Click Link settings

Choose People you choose

Set permission to Can view

Click Apply

In the people picker, add the SharePoint site group:

Typically named something like: <Site B Name> Members

Copy and share the link in the Teams channel

This grants access to all internal users and all external (guest) users who are members of the Team / Site B, without managing individuals.

Why “People in your organization” is not suitable here

If you select “People in your organization”, the link will:

Work only for users with an internal Contoso account

Exclude guest / external users

Continue to trigger access request prompts for guests

So for your scenario where external users must be able to play the video this option should be avoided.

Thank you for your time and understanding. If you need more help, or need to clarify anything please feel free to ask. I'm here to help.

Answer 2

When sharing a video stored in SharePoint Site A via a Teams channel that is backed by SharePoint Site B, external users who click the link will indeed be redirected to Site A and prompted to request access. This behavior occurs because the video file itself resides in Site A, and access permissions are tied to that specific site.

If you download the video from Site A and then upload it directly to SharePoint Site B, external users who have access to Site B should be able to watch the video without encountering additional access requests. This approach is generally recommended for external sharing, as it ensures that the content is stored in a location where the users already have the necessary permissions, thus avoiding any access issues.

This method simplifies the user experience for external guests, allowing them to access the video directly without needing to request permissions for another site.
