The desktop version of Outlook is perhaps one of the most popular email client apps in the world. However, while it might be a well-made application with many great features to stay on top of your messages, tasks, and appointments, sooner or later it may stop working.

When you least expect it, the app may get stuck in the loading splash with the 'Processing' message. It may stop responding, freeze, or break entirely as you try to open a file or send an important email.

Although there could be many reasons causing a problem, there are a number of general troubleshooting steps that you can follow to get the desktop Outlook app working again.

In this Windows 10 guide, we'll walk you through some troubleshooting steps to fix common problems with the desktop version of Outlook 2016.

How to fix 'Processing' message while opening Outlook

If Outlook gets stuck loading with the 'Processing' message, close the app, and launch it in safe mode to try fixing this problem using the following steps:

1. Use the Windows key + R keyboard shortcut to open the Run command.

2. Type the following command and press Enter to start Outlook in safe mode:

   outlook.exe /safe

How to install Windows 10 and Office updates

Although Windows 10 and Office can receive and install updates automatically, sometimes they may have some missing patches that could cause apps (such as Outlook) not to work correctly.

If Outlook refuses to work, or it's always freezing, you may want to check that your device has the latest updates installed.

Installing Windows updates

To make sure that Windows 10 is up-to-date, do the following:

Problems With Microsoft Outlook On Mac Pro

1. Open Settings.
2. Click on Update & Security.
3. Click on Windows Update.

4. Click the Check for updates button.

Installing Office updates

How to fix Outlook reinstalling Office

Sometime Outlook may stop responding or experience problems because of installation issues. Luckily, Office includes a repair utility to fix common problems with the suite of apps.

Problems With Microsoft Outlook On Mac Computer

To repair the installation, close any running Office application, and do the following:

Problems With Microsoft Outlook On Mac Windows 10

1. Open Settings.
2. Click on Apps.
3. Click on Apps & features.
4. Select the Office installation. (The name of the installation will be slightly different depending on the edition you have installed.)

   • Online repair (recommended): Resolves any issues with Office, but it requires an internet connection to download the necessary files to repair your applications.

7. Click the Repair button.

8. Click the Repair button again.

Once you've completed the steps, the repair tool will do a clean reinstallation of Office, and after the process, you should be able to use the Outlook 2016 app normally without issues.

How to fix Outlook data files

If after repairing the installation, you're still experiencing problems, then it could be something wrong with the Outlook data files.

Outlook 2016 uses two types of data files, including the Offline Outlook File (.ost) and the Outlook Data File (.pst), depending on the type of account you configured to store offline copies of your emails, contacts, calendars, and other items. If these files stop working for any reason, you can use the Office Inbox Repair Tool to scan and repair the files to get Outlook working again.

You can use this guide to repair the data files to fix problems with the Outlook app.

How to create a new Outlook profile

An Outlook profile contains a lot of settings that manage the behavior of the app. If you're experiencing issues, there's a chance that the profile might be damaged or a misconfiguration may be causing the problem.

To create a new profile, close Outlook, and do the following:

1. Open Control Panel.
2. Click on User Accounts.

3. Click on Mail.

4. Click the Show Profiles button.

5. Click the Add button.

6. Under 'Profile name,' enter a descriptive name for the profile.

7. Click OK.

13. Click Apply.
14. Click OK.
15. Open Outlook.
16. Use the 'Profile Name' drop-down menu, and select the new profile.

17. Click OK.

After completing the steps, it may take some time to load Outlook 2016 with the new profile, but after it's up and running, if you're no longer experiencing problems, then the issue was related to your old profile, and you should delete it.

Deleting a profile

To delete the old damaged profile, close Outlook, and do the following:

1. Open Control Panel.
2. Click on User Accounts.

3. Click on Mail.

4. Click the Show Profiles button.

5. Select the old profile.
