Microsoft Outlook is a subscription-based email client that can be installed on a user’s computer and configured to send and receive emails. Personal information like calendar appointments and entries, tasks, contacts, and notes can also be kept track of with it.

The Most Common Causes of Error: Outlook Not Responding When Sending Email

  • MS Outlook is an out-of-date application
  • More than one process is using the Outlook application
  • Add-in conflicts in Outlook
  • A mailbox that is quite large
  • Any MS Office program can get corrupted
  • Outlook’s data file or files are corrupted or damaged
  • Antivirus software conflicts with Microsoft Outlook
  • The Outlook profile of a user has been corrupted
  • Other apps that conflict with MS Outlook

What impact does This Issue Have on Microsoft Outlook Users?

The not responding notice shows on the title bar of the application’s window when an application or process becomes stuck in execution or reaches a resource stalemate. On a Windows system, this is true of all applications. The best option most of the time is to wait things out, even if it is frustrating!

When this happens to Outlook, the stakes are significantly higher because you could be in the middle of a chat with a potential client at any time. Worse, you could be waiting for an update to fix a critical security flaw when Outlook stops operating.

When you try to click anywhere in the Outlook window, the entire screen turns transparent, and the title bar displays the message “Microsoft Outlook not responding.”

Top Manual Methods to Tackle Outlook Not Responding When Sending Email Issue

You can attempt the following strategies to resolve the Microsoft Outlook stops working when sending email versions:

1. Updates Must be Installed

The version of Office on your computer is out of date. This can happen if your computer’s Windows Update isn’t set up to automatically download and install suggested updates. You can always fix problems by replacing out-of-date files and correcting vulnerabilities if you install crucial, recommended, and optional updates. As a result, make sure you have the most recent Outlook updates installed.

2. Outlook Processes That Aren’t Working

Microsoft Outlook has an annoying habit of hanging around even when the user repeatedly tries to shut it down. In technical terms, this means that one or more outlook.exe processes would remain in memory, preventing the Outlook application from properly terminating and preventing us, the users, from starting a new Outlook instance. This issue existed in previous versions of Outlook, and it may still occur in Outlook 2013 and 2010.

The first step is to terminate any Outlook processes that are still running. To do so, press Ctrl + Alt + Del on your keyboard, or right-click the taskbar and select Start Task Manager from the context menu. Then go to the Processes tab and look for all instances of OUTLOOK.EXE in the list. Select each OUTLOOK.EXE by clicking on it and then clicking the End Process button.

  • To open Run, press the Windows logo key + R shortcut.
  • In the Run bar, type Outlook.exe /safe and hit Enter.
