Documenten en media openen, delen en beheren in de Gratis versie van Microsoft Teams
Hi there! I'm Ben a fellow member here in the community.
With regards to this issue that you have, are there any error messages when you are trying to create a folder on your teams channel?
Also, is this the Microsoft teams app or Web you are using? You may not be able to create a folder in a Teams channel because your permissions are restricted or the "New Folder" command is disabled in SharePoint.
You can try the following steps in the meantime to try creating one:
Open Microsoft Teams and go to the specific team and channel where you want to add the folder.
- Click on the Files tab at the top of the channel.
- Click the + New button located on the toolbar.
- Select Folder from the dropdown menu.
- A dialog box will appear. Enter a name for your new folder and click Create.
