1. Go to the file in the Teams channel.
2. Click ... (More options) next to the file.

2. Ask the private channel owner to add you to the channel.

Troubleshooting Guest and External User Access

Guest User Access Issues

1. Ask the file owner to confirm the invitation was sent to your external email address.
2. Check your junk or spam folder for the sharing invitation.
3. Accept the invitation using the same email address it was sent to.
4. If you signed in with a personal Microsoft account instead of the invited email, sign out and sign in with the correct address.

External Sharing Restrictions

Your organisation may have external sharing disabled at the tenant level or for specific sites.

1. Contact your IT administrator to verify external sharing is enabled.
2. Ask if the site has specific sharing restrictions applied.
3. Check if the file has a sensitivity label that blocks external sharing.

Troubleshooting Conditional Access and MFA

1. Ensure you have completed multi-factor authentication (MFA) for your account.
2. If you are on a new device or network, complete any additional verification steps prompted by Conditional Access policies.
3. Try accessing the file in a private or incognito browser window to rule out cached credentials.
4. If you use a VPN, disconnect and try again, as some Conditional Access policies block access from certain locations.
5. Contact IT support if you receive a message stating your sign-in was blocked by a security policy.
