When launching Outlook 2016, you might receive an AppVIsvSubsystems32.dll error followed by the crash of your email client, and this can be pretty frustrating if you need to check your email.

Others describe that their Outlook 2016 crashes when opening – Event ID 1000. In one case or another, a few solutions might help you.

Why does Outlook 2016 keep crashing?

There can be several reasons why Outlook 2016 keeps crashing. However, here are some common causes:

• Add-ins – Outlook add-ins are third-party tools that can enhance the functionality of Outlook. However, sometimes add-ins can cause compatibility issues and make Outlook crash.
• Corrupted files – Outlook stores data in several files, including the Outlook data file (.pst or .ost) and the Navigation pane settings file. If any of these files become corrupted, it can cause Outlook to crash.
• Antivirus software – Some antivirus software can interfere with Outlook and cause it to crash. 
• Outdated Outlook version – If you’re using an outdated version of Outlook, it may have compatibility issues with your computer’s operating system or other software.

Before trying any solutions, if you need to check your email, you might want to try out a different email client temporarily.

Good email clients implement additional features that help you keep your inbox organized. For example, they can help you sort your contacts into customizable categories.
