What sensitivity labels do

Label a document (Word, Excel, PowerPoint)

1. Open your file while signed in with your Bowdoin account.
2. On the ribbon, select Sensitivity.
3. Choose the label that best fits the content. If a description appears, read it to confirm it matches your needs.
4. Continue working. You may see headers, footers, or a watermark added automatically.
5. Select Sensitivity again anytime to change the label. Some labels may prevent downgrading or sharing outside Bowdoin.
6. Save the file. The label travels with the file in OneDrive and SharePoint and is respected by supported apps.

Set a label when creating a team (recommended)

1. In Teams, select Create or join a team, then choose Create a team.
2. Before you finish creation, find the Sensitivity setting (it may appear on the creation form or under Privacy/Advanced options).
3. Select the appropriate label. The label can set the team’s privacy, external sharing, and device access rules.
4. Complete team creation. Files and the connected SharePoint site will follow the team’s label.

Change a label for an existing team (if allowed)

1. In Teams, open the team name, select More options (…), then choose Manage team or Edit team.
2. Look for Sensitivity or Team details. If the setting is available, pick a new label.
3. Confirm the change. The team’s privacy and sharing behavior may update to match the new label.

How labels work with channels and files

• Standard and private channels inherit the team’s label. You can’t set a different label per channel.
• Files stored in a team’s SharePoint site inherit the team/site label. You can still label individual documents with a more specific label if needed.
• Some labels may block external sharing or restrict downloads on unmanaged devices. If sharing is blocked, choose a different label that allows sharing or remove external access to sensitive content.

Troubleshooting and tips

• If you don’t see the Sensitivity button, make sure you are signed in with your Bowdoin account and that Office is up to date.
• If you are prompted to add a label, choose the best option based on the content. Prompts can appear when saving or sharing.
• If you cannot lower or remove a label, that action may be restricted. Choose a label that fits the content before you share.
• Labels and protections apply in Microsoft 365 apps and services that support sensitivity labels.
