Share a File Externally
Share a File Externally
Purpose: Ensure external users can access files while you maintain control over permissions and security.
Description
Securely share files with external partners, clients, or contractors to collaborate without creating risk or confusion.
When to use this
When you need to collaborate with someone outside your organisation and you want to avoid emailing attachments or losing track of versions.
Steps
- Store the file in a controlled location (a SharePoint library or the relevant Team’s Files).
- Select the file and choose Share.
- Open Link settings and choose the safest option that works (e.g. specific people, view-only, expiry if available).
- Enter the external person’s email address and send (or copy the link if your process requires it).
- Test access (or ask them to confirm) before the deadline hits.
Best practices
- Prefer sharing with specific people over “Anyone with the link” unless there’s a clear business reason.
- Use view-only by default; grant edit only when it’s genuinely required.
- Keep external collaboration in a shared team/site location (not personal OneDrive) so the business retains continuity.
- Use an expiry date for time-bound access whenever it’s available.
- Avoid downloading and re-uploading files during external collaboration (that creates version drift).
