Disabling IDLE for IMAP

 

The majority of mail clients employ a function called IDLE (otherwise known as IMAP push) to get new email notifications as quickly as possible. Unfortunately, this process can sometimes generate errors or other failures that result in connections to your server that use up your processes and generate large amounts of CPU usage.

If your email clients use the IDLE function with IMAP and you are receiving Internal Server Errors due to the number of processes open, or if you are experiencing issues with CPU usage, joudiSoft recommends disabling the IDLE function for your email client.

This article contains instructions for disabling IDLE on the following email clients:

 

Microsoft Outlook 2010

  1. Select the Send/Receive tab.
  2. From Send/Receive Groups, select Define Send/Receive Groups.
  3. For each Group, uncheck Schedule an automatic send/receive every x minutes.
  4. Click the Close button.
 

Microsoft Outlook 2007
