Fix Recommendation

Install a configuration profile to use SSL for Exchange ActiveSync.

Check Contents

Review configuration settings to confirm "Use SSL" for the Exchange account is enabled.

This check procedure is performed on both the Apple iOS management tool and the Apple iOS device.

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review.

In the Apple iOS management tool, verify "Use SSL" is checked under the Exchange payload.

Alternatively, verify the text "<key>SSL</key><true/>" appears in the configuration profile (.mobileconfig file).

On the Apple iOS device:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management".
4. Tap the Configuration Profile from the Apple iOS management tool containing the Exchange policy.
5. Tap "Accounts".
6. Tap the name of the Exchange account.
7. Verify "SSL" is set to "Yes".

If "Use SSL" is unchecked in the Apple iOS management tool, "<key>SSL</key><false/>" appears in the configuration profile, or the Exchange policy on the Apple iOS device from the Apple iOS management tool has "SSL" set to "No", this is a finding.
