Decrease in acceleration of MAPI traffic

Problem

The amount of acceleration experienced on MAPI traffic is not as much as has previously been experienced. The appliance may also be sending alerts about encrypted connections.

Resolution

  1. Encrypted communications or encrypted email and attachments cannot currently be decrypted by the Exinda. Verify that encryption is disabled on all client computers and that the MAPI protocol is not being encrypted. See Disable encryption on the Exchange server and Turn off MAPI encryption in Microsoft Outlook.
