When you try to open one of your folders in Outlook, an error ‘Cannot expand the folder. The set of folders cannot be opened. The information store could not be opened’ is encountered.
You try to close and re-open Outlook but it doesn’t work. You also try to restart your system and re-open but no luck. Here in this post, we explain some solutions you can try to resolve the issue.
Potential solutions to resolve the issue
Solution 1: Remove the account in question and set it up again
Removing the affected account and setting it up again will help resolve the issue in most cases. Just follow the steps to remove the account.
- Open-File > Account settings menu
- Select the email account to remove
- Click on Remove button
- Confirm the removal by clicking on the Yes button
The steps are very similar to Outlook 2007 as well, with only a minor difference
- Go to Tools > Account settings
- Go to the Email tab
- Select the email account to remove
- Click Remove and confirm by clicking on the Yes button
Once you have removed the account, you can set it up again. To do that,
- Select File > Add Account
- For Outlook 365 and 2016, enter the email and click on the Connect button
- For Outlook 2013 and 2010, enter the name, email, and password
- Enter password if required and click Finish
Now that you are done removing your email account and setting it up again, try opening the folders. Ideally, you should be able to do it without any problems.
Solution 2: Repair PST file
If the problem still persists, it could be that your PST file is corrupted. PST files are data files that store Outlook data on your system. You will have to repair them to fix your Outlook. For this purpose, there is a handy built-in tool called Scanpst.exe.
To run the tool, search for Scanpst.exe in the Search bar. Then select your PST file and click Repair.
Note: You can find the location of your PST file within Outlook. Click on File > Account Settings > Account Settings; then select Data files tab and choose your file. Then click on Open File Location to find the location of your file.
However, the disadvantage is that Scanpst can repair minor corruptions and may have to be run several times to fix the issue. Refer Microsoft Outlook inbox repair tool not responding if the tool does not respond.
