Outlook Not Responding

Reason: Why Is Outlook Not Responding?

Microsoft Outlook is part of the “Email Clients” category of software. These are programmable email tools that are installed on your computer and allow you to send and receive emails. “Webmail,” on the other hand, only allows users to access emails using web browsers. Microsoft Outlook is unquestionably one of the most versatile ‘Email Client’ technologies available today, which may explain why it is used to manage emails by enterprises all over the world.

Outlook, like any other software, is prone to errors and difficulties, which are usually inconvenient and, in the worst-case scenario, stop you in your tracks. The “Outlook not responding” error is one of the most prevalent issues that users encounter. This warning is frequently displayed when Windows is unable to communicate with a programme running on your computer quickly enough. In light of this, we’ve compiled a list of possible causes for Microsoft Outlook to cease responding.

  • You haven’t updates recent changes.
  • Another process is using the outlook.
  • External content, such as images in an email message, is being loaded by Outlook.
  • Outlook is being hampered by a previously installed add-in.
  • Your mailboxes are excessively big.
  • The location of your AppData folder has been changed to a network location.
  • Your Office programmes must be repaired.
  • The data and user files in Outlook have been corrupted or damaged.
  • Your antivirus software is either outdated or incompatible with Outlook.
  • Outlook is incompatible with another programme.

Effective Ways to Fix “Outlook Not Responding” Error.

Other Programs/Applications Should Be Closed.

Microsoft Outlook is the most complicated programme in the Office suite, according to Microsoft. Because you have so many other programmes open on your computer, Outlook will occasionally freeze. In most cases, Outlook hangs when loading profiles or performing any other operation due to a lack of memory. It frequently occurs when you use old PCs with insufficient internal memory. Even if you use a modern computer with plenty of memory, you might run into this problem. As a result, it is recommended that you close all other programmes before using Microsoft Outlook.

Turn Off Your Antivirus Software.

Remember to add the Outlook application and its add-ins to your antivirus program’s trusted list. If the problem persists, you should try turning off your antivirus programme and seeing if Outlook functions normally. If it is, your antivirus programme is the source of the problem. To fix this problem, make sure your antivirus software is up to date. Antivirus software that is outdated or overly protective of your computer may conflict with Microsoft Outlook or any Outlook add-ins you have installed.

As a result, the Antivirus programme will disable the add-ins and prevent Outlook from working properly. Also, make sure the antivirus programme you’re using is provided by a reputable and trustworthy vendor. Microsoft Office applications are not incompatible with a good antivirus programme.

Start Outlook in safe mode.

It is strongly recommended that you run Microsoft Outlook in safe mode whenever something goes wrong. If you run Outlook in safe mode, the add-ins and other customization files will be removed from the programme. To run Outlook in safe mode, hold down the Ctrl key while clicking on the Outlook icon, or type “outlook.exe/safe” into the command prompt. Then, on the screen, you’ll see a confirmation message asking if you want to start Outlook in safe mode. To run Outlook in safe mode, you must select Yes.

Cancel Outlook’s Hanging processes.

Working with Microsoft Outlook becomes extremely inconvenient if it keeps hanging. Have you ever been in a situation where you keep trying to close Outlook but it just won’t go away? Maybe you’re trying to delete or transfer a large number of emails from one folder to another. The Outlook application hangs in any of these situations. But you never know if everything is running smoothly behind the scenes. It would be beneficial if you waited a few minutes for Outlook to complete the process and resume normal operations.

One or more Outlook processes may also be running in the background from time to time. It’s possible that it’ll make Outlook unusable. To fix this problem, 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 of the outlook.exe items in the list. You can select and cancel them one at a time by clicking the “End Process” button.

Disable Add-ins for Outlook.

If the above solutions don’t work, you might try disabling Outlook add-ins to fix the Outlook error. A faulty Outlook add-in can sometimes cause the unexpected issue “Outlook not responding.” If you’ve recently installed some add-ins, it’s a good idea to turn them off one by one and return to whatever you were doing before. If Outlook is functioning normally, it’s likely that one of the add-ins you installed earlier was the real culprit. Always make sure you’re downloading Outlook add-ins from a reputable source.

Reduce the size of the Outlook data file.

A large Outlook data file can sometimes be the cause of Outlook’s inactivity. The maximum size of an Outlook data file is 20 GB. It’s only 2 GB in older versions of Outlook. Outlook freezes whenever the file size reaches its maximum limit while in use. You can solve this problem in a variety of ways, including:

  • Rather than storing all of your email messages in a single mailbox folder, you should separate them into subfolders. Assume that the Inbox folder in Outlook contains thousands of emails. To read an old email, you open the folder. Outlook will take a long time to open due to the thousands of email messages stored in that folder. Furthermore, if you click any of the emails while Outlook is loading the mailbox folder, the programme may freeze or hang. You can get around this problem by simply creating a few subfolders in which to store your email messages.
  • When the PST file reaches its maximum size, it’s also a good idea to compress it. It’s important to remember that deleting some of the unwanted email messages from the Outlook data file will not reduce the file size. Only by compacting the Outlook data file with Outlook’s built-in Compact feature can the file be reduced. Don’t forget to empty the Deleted Items folder before compacting the PST file.
  • You can split a large PST file into two or more parts if the file size is extremely large. This will result in a number of small PST files that can be easily opened in Outlook.

Office Repair and Installation.

If you have a problem with the Microsoft Office suite, you may experience issues such as Outlook not responding, hanging, crashing, or freezing.

As a result, it is preferable to repair Office installation and see if the problem is resolved. Follow the simple steps below to repair your Office installation:

  • Change can be found by right-clicking Microsoft Office and selecting Change.
  • On the screen, the Microsoft Office Professional dialogue box will appear. To repair Office installation, select Repair and then click Continue.

Outlook Data File Repair.

The Inbox Repair tool, also known as the scanpst utility, can be used to scan and repair corrupt Outlook data files (both OST and PST).
