Is it possible to share Azure hosted SMB file shares across different tenants?

Hi Leon,

Azure File Shares is definitely not the right solution for this. It is meant to replace on-prem file shares with a cloud solution.

I think what you should be looking into is getting your files properly sorted and getting it into Teams/SharePoint.

SharePoint is built for these types of situations, and on top of it you can use the SYNC button, which makes it looks like a SMB share (attaches a folder to your desktop). You can invite Guests into your tenant and do sharing that way to simplify your permissions.

If this is helpful please accept answer.

Hi @LeonT,

Thank you for posting your query here!

Azure SMB file shares are typically associated with a specific Azure Active Directory (Azure AD) tenant, which means that they are not directly shareable across different tenants. Azure SMB file shares are designed for use within a single tenant's environment, and access control is managed through Azure AD authentication and authorization mechanisms.

However, you can invite users from other Azure AD tenants to collaborate with your tenant using Azure AD B2B collaboration. This allows external users to access resources within your tenant, but it doesn't directly share the SMB file shares across tenants. Users from other tenants would need to authenticate as guest users in your tenant and be granted appropriate access to the SMB file shares.

Hope this helps!
