Fixed: Outlook Crashes When Replying to Email

"I'm new to using Outlook for work, and it's been an interesting learning experience so far. However, I've encountered a frustrating issue recently. Whenever I attempt to reply to an email in Outlook, the application crashes. I've tried restarting both Outlook and my computer, but the problem persists. If anyone has insights into what might be causing this and how to resolve it, I would greatly appreciate your help."

Outlook crashes when replying to an email, and one possible reason for this is a corrupt delivery location or folder where the message is supposed to be delivered.

The error statement that may popup while replying to an email is “Outlook not responding.”

Why does Outlook crash while replying to an email?

Outlook may crash while replying to an email because the delivery location or the folder where the message is going to be delivered is corrupt. This means you are trying to reply to a folder that does not exist. But you will only face this issue, if your account has a POP3 configuration. But if this is not the case with you, then we are going to mention the most possible reasons. Here are some of the reasons that may lead to this issue:

• Outdated version of Outlook.
• Recently added add-ins.
• Any other instances of Outlook that are running in the background.
• Bulky mailboxes.
• Fault in Office programs.
• The conflict between antivirus program and Outlook.
• Corrupted user profile.
• Any other program is conflicting with Outlook.
• Corrupt, damaged, or broken Outlook data file
• Redirection of AppData folder to a network location

These are the potential reasons that could lead to this issue, and we've provided some known solutions that might help you resolve it quickly. For instance, if you have multiple instances of Outlook running in the background, you can try closing all of them and see if that resolves the problem. Additionally, you can attempt the following solutions for an immediate fix:

• Update Outlook
• Update Windows
• Update MS Office
• Close all the other programs running in the background

Please attempt all the solutions provided above and see if any of them resolve your issue. In some cases, you can use the advanced diagnostics offered by Outlook to automatically fix the problem. To do this, follow these steps:
