Teams channel folder permissions

Hi

I have a couple question and was hoping someone get help.

If you have a private channel and several folders. If some members need read only access to folders and other members read/write. If you open the folder in sharepoint, the permissions can be set thru manage access. Permissions as owner, visitors and members.
1. If the members permissions is write access, how to do set read only access to members?

  1. If the sub channel is public or private are the only folder permissions owners, visitors and members?

  2. Does it really matter if you change the folder permissions thru sharepoint>manage access vs Sharepoint>Documents : Settings> permission for this document library?

If you need to maintain read-only access, Teams and private channels might not be the best solution for you. Both are build on the principle of "equal access for all members", and in some cases this can be extended to every used in the organization. While you can certainly break permission inheritance/modify the permissions, this is not a supported scenario and you should do so with caution.

Hi

I am currently looking into migrating a file server shared to Teams/SP. I might have some folders that require read-only access.
Do you have any other suggestions?

With the document library view limit of more than 5000 items. If I have a 1TB of file shares. What's really the best method for folder structure in Teams/Sharepoint. Is it to setup multiple library documents or several sub channels?


Thanks for your advice.

Hi @VirtualTech-7803,

To answer your questions:

①We could not set read only access to members group, which has the default Edit permission, if we set "Can view" for the user, it will be moved to Visitors group automatically.

②There is no sub-channel in Teams, if we add a new folder under the private channel folder, it will inheirt permissions from its parent.

③If you change the permission for the document library, it will also affect the folder permission, as document library is the parent of folder.

Thanks for answering my questions.

  1. Correct. Under documents, I created a new folder and added a new read only permission group and the user with member access to the channel could still edit the file.

  2. Correct, only members will have access to a private channel

I would appreciate if you can answer another question. Are there any differences between the permissions applied to a sharepoint library vs teams?
I think the permissions are the same in Teams/SP. Teams folders/files in SharePoint>Manage access permissions are members , visitors and owners. Also advanced permissions in SP. I think in advance options, company users, not members of the channel can be manually added in advance with some permissions.

Hi @VirtualTech-7803,

For scenarios where a SharePoint site is used with Teams, we recommend doing all permission management through Teams.

As with Microsoft 365 groups, team owners become site owners and team members become site members.

View-only permissions are managed through the site.

Permissions and file security options set in SharePoint are automatically reflected within Teams.

Thanks @JulieWang-MSFT Very help-ful links.

Last question. I understand is recommend to manager the permissions in teams if SharePoint is used. So if a SharePoint site is created with multiple libraries and users are accessing the files in Teams thru Document Library Tab. Are the file permissions still best to manage in Teams?

FYI custom permissions on Private Channel content is not supported and may revert at any time. SharePoint and Teams use the same M365 Group; the M365 Group is granted Edit access on the SPO site.

Visitors is not tied to Microsoft Teams as Teams does not support a view-only permission level.

@JulieWang-MSFT - Your answers did help. I think I have a better understanding of what I need to do.

Teams will will have a single document library used by Teams. If you move files from the file share to the appropriate channel/subfolder, then permissions will be in place based on the Team membership.
I understand teams does not support read-only. I think others are managing the read-only thru SharePoint Advance settings permissions. Perhaps this is not best practice.


SharePoint site with other libraries, as you've found there is no way to manage those files via Teams, other than adding a document library tab, which means you're really managing files via SharePoint, not Teams.

Hi @VirtualTech-7803,

Yes, you can store and share files using ​SharePoint, OneDrive, and Microsoft Teams.

SharePoint underpins each of these tools, but each can be used in their own ways to accelerate collaboration and efficiency in different situations.
