Sensitivity labels¶
You state how sensitive a message is with a label. Recipients see the label as a banner at the top of the message; some labels limit the number of recipients or forwarding.
EveryoneLabels are defined by your organisation
Labelling a message¶
- Press New Message.
- On the toolbar, click the Sensitivity button next to Encrypt. Your organisation's active labels are listed (for example TASNİF DIŞI, HİZMETE ÖZEL, GİZLİ).
- Choose a label.

The button takes the name of the label you chose, and a coloured Sensitivity label banner appears below the subject line.

- Write the message as usual and press Send.
To remove the label, choose (none) in the list. In your inbox, labelled messages show a small Sensitivity: … badge in the list.
Label rules¶
Your organisation can attach rules to some labels. If a message breaks a rule you get an explanatory warning and the message is not sent:
| Warning | What to do |
|---|---|
| … can be sent to only one recipient. | Remove the extra recipients. |
| … does not allow CC or BCC. | Remove the CC and BCC recipients. |
| You cannot send without a label | Your organisation made labels mandatory; choose one. |
| External recipient warning | Sending outside the organisation needs confirmation; check the recipients and confirm. |
If you cannot see the label list
If you see "(no active labels)" or "Could not load sensitivity labels", contact your organisation's administrator.
A label is not encryption
A label classifies the message and applies rules; it does not encrypt the content. For end-to-end confidentiality use PGP encryption.
