1. Perform Some Preliminary Checks

Before moving on to any serious troubleshooting, perform the following preliminary checks first, as they may resolve the error right away:

  • Close other open email clients, especially the Mail app that comes built into Windows.
  • Run Outlook as administrator. Right-click on the Outlook client and hit Run as administrator.
    Run Outlook as an Administrator in Windows
  • Ensure you have the compatible version of Outlook (x32 or x64) installed on your device.
  • Update or repair Outlook to ensure a corrupt or outdated installation has not caused the error.

If the basic checks and fixes do not resolve the error, it’s time to move on to serious troubleshooting.

2. Check for Add-In Interference

The add-in interference is the leading cause of Outlook not launching and presenting the “the set of folders cannot be opened” error, as reported by numerous users on various online forums. Running Outlook in Safe mode is the best way to confirm that since it launches the app without add-ins and other elements.

Press Win + R, type “Outlook.exe /safe” and hit Enter to launch Outlook in safe mode.

If the app launches without an error, the add-in interference must have been the culprit. Therefore, stay in safe mode and turn off any interfering add-ins. Here’s how:

  1. Go to the File tab and select Options.
    Select Options in the File Tab of Outlook
  2. Go to the Add-ins tab in the left menu.
  3. Select “COM Add-ins” from the Manage menu, then click Go.
    Click on the Go Button After Selecting the COM Add-ins Option From the Manage Dropdown Menu in Outlook
  4. Uncheck the boxes behind any add-ins you don’t need and disable them.

3. Check for Issues With the OST File

The mislocated OST file or its corruption can also lead to the error. Therefore, ensure the file is at its original location and recreate it to eliminate the possibility of file corruption. Here’s how:

  1. Open the Control Panel.
  2. Click on the View by dropdown menu and select Large icons.
  3. Go to Mail (Microsoft Outlook).
    Go to Mail Option in the Windows Control Panel
  4. Click the Data Files… button.
  5. Select the OST file location and click Open File Location…
    Click the Open File Location Button After Selecting the OST File in the Data Files Tab
  6. Right-click the file in the File Explorer and select Properties. If the file type is OST, the file is in the right place, and no action is needed.

Ensure the File Type Is OST by Going to Properties in the Windows File Explorer

To ensure that the OST file is not corrupt, copy it to a safe location outside the Outlook installation folder. Then, right-click and delete the main OST file.

After that, restart Outlook, and it will automatically recreate the OST file and download the data from the Exchange Server. If you decide to go this route, remain connected to the internet.

4. Check for Issues With Your Outlook Profile

Outlook uses the Outlook profile to store information about your email accounts, data files, and other client settings. Profile corruption can prevent Outlook from loading the necessary data at launch and can present the “set of folders cannot be opened” error. To rule out profile corruption as the cause of the problem, follow these steps:

  1. Open the Control Panel.
  2. Click on the View by dropdown menu and select Large icons.
  3. Go to Mail (Microsoft Outlook).
  4. Click the Show Profiles button.
  5. Click on the Add button.
    Click on the Add Button in the Show Profiles Menu in Mail Microsoft Outlook Settings in the Windows Control Panel
  6. Follow the instructions on the screen to create your new profile.

  1. Launch a new Outlook profile.

If Outlook launches successfully, a corrupt profile could be to blame. So, continue to use the new profile after adding your account. If switching profiles does not help, go to the next step.

5. Look for Issues With the Navigation Pane

Misconfigured navigation pane settings or corrupted XML files, which store the navigation pane settings, can also prevent Outlook from opening and presenting the error. To eliminate this possibility, you should reset the navigation pane in Outlook that will reset the configuration to its default settings. Press Win + R, type “outlook.exe /resetnavpane” and hit Enter.

Run a Command to Reset the Navigation Pane in Outlook

After that, relaunch Outlook. If resetting the navigation pane doesn’t work, you should delete the XML file manually. To do this, press Win + R, type “%localappdata%\Microsoft\Outlook” and hit Enter. After that, delete any XML files you find in this folder.

Then, restart Outlook from scratch, and it will recreate the XML file with default settings. There’s a good chance that it will resolve the issue.

6. Repair the Outlook PST Files

PST files store data about contacts, calendars, events, and messages. If the error window indicates that Outlook could not open the PST file, then the file could be corrupt, which could be why Outlook presents the error. Therefore, you can fix it by repairing the files. To repair the corrupted data files, follow the below steps:

  1. Navigate to the Outlook installation folder, which is located here by default:
    C:\Program Files\Microsoft Office\root\Office16
  2. Locate the ScanPST.exe file and run it.
  3. Click Browse, paste the path from the error window into the Inbox Repair tool, and click Start.
    Click Start After Pasting the Path From the Error Window into the Inbox Repair Tool
  4. Then, click the Repair button to complete the repair.

If you can’t locate the Outlook folder in the path mentioned above, see our guide on repairing the PST file for the exact path.

7. Run the Microsoft Support and Recovery Assistant

If none of the above fixes resolves the error, run the Microsoft Support and Recovery Assistant, Microsoft’s recommended tool for fixing issues with Microsoft Office products.

Here’s how to download and use the tool:

  1. Download Microsoft Support and Recovery Assistant from the Microsoft website .
  2. Unzip the file you just downloaded.
  3. Run the SaraSetup file to install the software.
  4. Upon installation, launch the tool and click the “I agree” button.
  5. Select Outlook from the list of applications and click Next.
    Click Next After Selecting Outlook From the List of Apps in the Microsoft Support and Recovery Assistant Window
  6. Then, follow the on-screen instructions to carry out the repair.

If any underlying problem with the Outlook client contributed to this issue, running this tool will most likely resolve the issue.
