Check Contents

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

This check procedure is performed on both the Apple iOS/iPadOS management tool and the iPhone and iPad.

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/iPadOS management tool, verify "Use SSL for incoming mail" is checked under the Exchange payload.

On the iPhone and iPad:
1. Open the Settings app.
2. Tap "General".
3. Tap "VPN & Device Management".
4. Tap the Configuration Profile from the Apple iOS/iPadOS management tool containing the Exchange policy.
5. Tap "Mail".
6. Tap the name of the Exchange account.
7. Verify "SSL for incoming mail" is set to "Yes".

If "Use SSL for incoming mail" is unchecked in the Apple iOS/iPadOS management tool or the Exchange policy on the iPhone and iPad has "SSL for incoming mail" set to "No", this is a finding.
