Is Outlook stuck on a screen that simply says "Processing"?

Or does Outlook hang, freeze, or stop working when you're opening a file or sending an email message?

If you’ve used Microsoft Outlook for an extended period of time, you may have noticed that it doesn’t run quite as smoothly as it used to.

Outlook’s performance is affected by many things, including the amount of data it has to keep track of, any add-ons that are installed, how often it checks for new mail (checking more frequently can improve performance), and various other factors.
