A few days back due to some technical fault in my system, I had to use Microsoft Outlook on a different machine. While starting with my Outlook 2016, I was encountered with an error message, “Something is wrong with one of the data files, and Microsoft Outlook Needs to close.” Since I am from a non-technical background, I had to rely on an IT professional to deal with this sudden nightmare. The gentle guy used in-built Inbox Repair Tool to run my entire Outlook and see if the error persists. But unfortunately, this solution was short-lived as on the 3rd day, I bumped into the same error. This was my personal experience when I had to suffer with such issues.

After all the bad experience, I decided to attain supportive knowledge of the causes of this error and native ways to resolve it.

Common causes for this error

  • Error in network devices installation- network devices such as routers, hub, firewall, bridge, repeater, etc. might become a hindrance for Outlook. The occurrence of this error can be caused due to the error in their installation procedure.
  • Outdated version of MS Office suite- if you have the latest version of Windows on your system but on the contrary, you are using an outdated version of Microsoft Office suite then the possibility of the error increases.
  • Inappropriate settings in Office Suite- another possible reason for this error is if any proxy settings are enabled on the system, these settings can cause an error in Office Suite installation.

Disable firewall or any other network device and then restart Outlook. There are high chances that the error will no more persist, but if yes, then follow the next solution.
  2. UNINSTALL AND REINSTALL OFFICE SUITE- As mentioned above, one of the major cause for this error is using an outdated version of Office. To tackle this issue, you first need to uninstall the older version of Office Suite. If you already have an MS Office account, log in to your account and install the latest version. Now use the latest version of Microsoft Outlook and see if the error persists.
  3. UPDATE IN WINDOWS REGISTRY- There might be a problem with Windows Registry when none of the above solutions work.

Step 2- Check the value of Current Window. If the value is 1, change it to 0.

      The older version of Outlook were relatively simple than the newer once. They can contain the graphic parts like audio, video, and presentations in the emails more effectively.
