Turn off MAPI encryption in Microsoft Outlook

Exinda recommends that encryption of contents and attachment for output messages should be disabled to maximize reductionmeasures the amount of redundant data that has been removed from the network, increasing capacity, as each user will encrypt files with a different key. MAPI Encryption is a client side configuration parameter in Outlook. Therefore, to disable MAPI encryption you need to make the change on each Outlook client.

You must disable encryption on all Microsoft Outlook clients as well as the Exchange server. See For more information refer to Disable encryption on the Exchange server..


These parameters are configurable through a global change so that each client does not need to be individually changed.
