Outlook Crashing [Solved!]

Outlook crashing is a significant problem as the whole work might go in vain in an instant.

If your Outlook keeps crashing or crashes frequently, there can be multiple reasons behind it. However, we are sure that we can help you fix this crashing issue with this article.

Make sure to read the article till the end. You can use the following quick links to jump to a specific section.

Before moving to the troubleshooting methods, we must first understand why Outlook crashes to find efficient solutions.

Why does Outlook keep crashing?

There can be several reasons behind Outlook crashing. Some of them are mentioned below:

Corruption of Outlook profile

You must create an Outlook profile to use it. However, invalid login attempts, faulty add-ons, sudden system shutdowns, etc. can corrupt the Outlook profile.

A new profile can replace a corrupt Outlook profile and fix the issue.

Conflicting add-ins

Clashing of add-ins’ processes can crash the Outlook. The incompatibility might also happen with the default processes of operations and that of add-ins.

Conflicting operations will lead to Outlook crashing again and again while performing certain tasks. Such as Outlook 2013 crashing on startup or printing in Windows 7 and Outlook 2016 crashing on printing.

Disabling all add-ins and enabling them one by one can help detect conflicting add-ins.

Damaged or corrupted data files

Outlook data files are prone to damage and corruption when they are of large size. Third-party applications and add-ins can also alter data files causing them to get corrupted.

Luckily, you can create a new Outlook data file if the current one is damaged.

Corrupted Outlook installation files

Corrupt installation files can lead to random crashes on Outlook.

Rather than downloading Outlook or other Microsoft apps from third-party websites, download them from the official website.
