🔗 How Teams + SharePoint Store Files

Files shared in Teams channels are stored in the connected SharePoint site’s Documents library (each channel = a folder). Teams is your collaboration front‑end; SharePoint is the secure repository with versioning, permissions, and compliance.

Note: Use Open in SharePoint from the Teams Files tab to jump to the real storage location.

🔄 What Version History Does (and Why It Matters)

• Captures a new version at each save or co‑authoring checkpoint
• Shows who changed what and when
• Lets you open, compare, or restore older versions
• Protects against accidental overwrites or deletes

Tip: Versioning is enabled by default on modern libraries. For records or critical docs, keep more major versions and require check‑out if needed.

📍 Access Version History (Step‑by‑Step)

From Microsoft Teams

1. Open the channel → Files tab
2. Click the … next to the file → Open in SharePoint
3. Select the file → Version History

Directly in SharePoint

1. Go to the SharePoint Document Library
2. Click the file’s … (or right‑click)
3. Select Version History

Good to know: In Office apps (Word, Excel, PowerPoint), use File → Info → Version History to compare or restore without leaving the app.

🧭 Restore & Compare Versions

Restore a previous version

1. Open Version History
2. Expand the version row
3. Click Restore → it becomes the latest version (no data lost)

Compare versions

Open a prior version in Word/Excel/PowerPoint (read‑only) and use the app’s Compare tools to review changes.

Caution: Deleting a version removes only that snapshot, not the file. Keep key milestones labeled via Comments when saving.

🔐 Permissions Fundamentals

• Owners: full control, can change permissions
• Members: can edit and upload
• Visitors: read‑only
• External Guests: access via links or guest accounts (if allowed)

Note: Team membership maps to SharePoint site permissions. Fine‑grained access (file/folder) is handled in SharePoint’s Manage Access.

🛡 Manage Access (Step‑by‑Step)

View or change access

1. Select a file/folder in SharePoint
2. Open the Details pane (the ⓘ icon)
3. Click Manage Access
4. Use Add People (choose Can View or Can Edit)
5. To remove access, click the ✕ next to a person/group

Avoid permission sprawl

• Use groups over individual assignments
• Avoid breaking inheritance unless essential
• Review access on sensitive libraries quarterly

🔗 Link Sharing Best Practices

• People with existing access: safest inside the team
• People in your organization: broad internal share
• Specific people: targeted; best for external collaboration

Tip: Default to View for external links; enable Edit only when truly required. Set link expiration for temporary access.

⚖️ Security & Governance Tips

• Use retention labels for records and legal obligations
• Enable auditing and review access logs for sensitive content
• Apply sensitivity labels to encrypt confidential files
• Document a naming convention and lifecycle (draft → review → final)
