Unable to share folders externally
Do you know the status of the organization-level external sharing setting in your tenant?
Sign in to https://admin.microsoft.com/ as a global or SharePoint admin. (If you see a message that you don't have permission to access the page, you don't have Office 365 administrator permissions in your organization.)
Note
If you have Office 365 Germany, sign in at https://portal.office.de/. If you have Office 365 operated by 21Vianet (China), sign in at https://login.partner.microsoftonline.cn/. Then select the Admin tile to open the admin center.
In the left pane, under Admin centers, select SharePoint. (You might need to select Show allto see the list of admin centers.)
If the classic SharePoint admin center appears, select Open it now at the top of the page to open the new SharePoint admin center.
In the left pane of the new SharePoint admin center, under Policies, select Sharing.
Under External sharing, specify your sharing level for SharePoint and OneDrive. The default level for both is "Anyone."
