Exchange ActiveSync

Exchange ActiveSync lets users access corporate data stored in the Exchange server or any other EAS compliant server. Users can access information such as e-mails, contacts, calendar, and tasks even when they are offline. EAS can be configured to use SSL encryption to establish secure communication between the EAS host and the managed devices. Also, MDM lets you store and view e-mail attachments using the ManageEngine MDM app.

FEATURES	DESCRIPTION
Account Name	You can specify a name for your Exchange ActiveSync account. This name is not mandatory and is only used for reference.
Exchange Host Type	Specify the type of the Exchange Server - whether it is Office 365 or Exchange On-Premises.
Exchange Server	Specify the details of the Exchange Server. If Exchange Host Type is selected as Office 365, then Exchange Server is pre-filled as outlook.office365.com else the server name has to be specified.
CONFIGURATION DETAILS
User Name	The username or login name usually consists of the user's name and domain-based suffix. Use %upn% to fetch the username mapped to the device.
Identity Certificate	Specify the Identity certificate to be used for EAS. If no certificate has been added yet, you can upload a certificate.
OAuth (supported for iOS 12 or later versions)	Enabling OAuth ensures that the Exchange client does not access the user's credentials. The users are redirected to Exchange Online to log into their account.

If an Exchange account has been previously configured on the device, the same account cannot be configured using MDM.
If the Add/ Modify account restriction has been applied to the device, the user is prompted to enter the password only once. If the user enters the wrong password, the profile has to be redistributed to prompt for password.

NOTE: Ensure that the maximum limit on the number of devices per mailbox is not breached while pushing Exchange Activesync profile.

Troubleshooting tips

I've changed passcode for the Exchange accounts of all users. But they're still able to access it as they've logged in previously. How do I ensure the user logs in with the new passcode?

Open IIS on the server machine, where your Exchange Server is running.
In the Connections pane, expand the Server node and click Application Pools.
In the Application Pools page, select MSExchangeSyncAppPool and click on Recycle and follow the on-screen instructions to refresh the session tokens on the devices. Users whose password has been changed are prompted for the new password, as the old password cannot renew the session.
