Even being one of the primary email service providers, many users still come across different error messages in Outlook. One of them is “Microsoft Outlook has encountered a problem and needs to close”. When someone encounters this error, they cannot open and access their emails, contacts, and other Outlook data until this error is resolved. This makes it hard for user to keep on doing their work.

But what causes this error or why is this an issue that we need to address? There can be many reasons why Outlook crashes frequently. Some of these issues may be directly related to the Outlook application itself, while there may be a few that might be related to system configuration or another application. To delve into the depths of this question, we need to read on.

Causes of Microsoft Outlook has encountered a problem and needs to close error

Few of the most common causes of Microsoft Outlook has encountered a problem and needs to close error are as follows:

  • Virus or Malware Attack: Yes, a virus or malware attack can harm not only your operating system but various applications and their functioning as well. Such malware can enter your system through emails. So, if your Outlook is crashing too often, it may be due to a malware or virus attack.
  • Corrupted PST File Header: A PST file can get corrupted due to hardware or software related issues. As a result, it can hamper the smooth functioning of Outlook application and even lead to abrupt shut down of the application.
  • Third-party Add-ins: Outlook Add-ins can lead to issues if the add-ins are not from trusted vendors or if they are incompatible with the Outlook version installed on your machine. Usually, third-party add-ins are the reason behind Outlook application crash related issues.
  • Corrupted Outlook Binaries: Manually editing, renaming, or deleting any application-related dll or binary files can often cause a wide range of issues. Make sure not to modify any such libraries or system files without complete knowledge of the outcome of such actions.
  • System Resource Allocation Issues: There may be chances that another application is using your Outlook application, and hence you are not able to access it. Further, the lack of system resources such as CPU, memory, storage, and virtual space can also lead to Outlook crash. Another possibility is that Outlook starts consuming more than the normal number of resources due to any malfunction. And when the system resources run out, it starts crashing.
  • Corrupt Email Attachments: If Outlook crashes sometimes occur only when you try to open a particular email attachment, the issue may be due to corrupt file attachment. On the other hand, If the issue occurs with multiple email attachments or a particular file type as an attachment, you may need to troubleshoot it differently as the file may not be corrupt.
  • Oversized PST File: Outlook has a default limit of 2GB for PST files (for older versions). Although it is sufficient for level tasks, PST size keeps growing if it is not managed or archived periodically. If the PST file size grows beyond this limit, then it can lead to Outlook crashes.

Apart from these there are many other causes. However, there are also, multiple methods to resolve this issue, using either the manual or the mechanical methods.
