Outlook crashes because of a faulty module called KERNELBASE.DLL, as is evident from the “Problem Signature” (which can be found by clicking on “Show Problem Details” at the bottom of the error pop-up). As a result, the most obvious and immediate problem that users face is mailbox inaccessibility.
Following are some of the plausible causes behind the Outlook error (after reading through multiple forums), and solutions:
Faulty or damaged add-ins can also cause KERNELBASE.dll issue.
Follow the below-listed steps to disable Outlook add-ins:
If Outlook is Accessible
If you can access Outlook, try finding the problematic add-ins and disable them by using the following steps:
To check which add-in caused the problem, enable the disabled add-ins one by one and verify the effect at each step. You will eventually find the faulty add-in this way. Remove it and enable everything else to resume your work.
If you are unable to launch Outlook
If Outlook is not opening, try the following steps to disable all add-ins:
This will launch Outlook without add-ins and give you an opportunity to enable each one-by-one to find the faulty one. If this fix doesn’t work, the problem might not be with add-ins.
If you can open Outlook application and access its data file by logging to a different profile, then likely a corrupt Outlook (user) profile may be causing the error. The profile can become corrupt due to Outlook Data File (PST) corruption.
Follow these steps to create a new Outlook profile:
Restart Outlook and check if the issue is resolved.
If creating a new profile doesn’t solve the issue, try repairing the data file by using Microsoft’s inbuilt Inbox Repair Utility, also called ScanPST.exe. The utility can detect and fix minor issues within the Outlook PST file and make it usable again. The steps to repair PST file with ‘ScanPST.exe’ are listed below:
Step 1: Navigate to Outlook installation folder and locate ScanPST.exe file.
NOTE: The file is usually located at the path ‘C:\Program Files\Microsoft Office\OFFICE’. However, the location will vary depending on the Outlook version you are using.
Step 2: Double-click the ScanPST.exe file to launch it.
Step 3: In the window that appears, click Browse to select the corrupt PST file.
Step 4: Click Start to begin the scanning process.
Step 5: If errors are found after the scan process, click Repair to fix the corrupt file.
ScanPST.exe can only handle minor corruption errors in the PST file, and cannot repair the severely corrupt files. But, you can handle severe corruption errors in Outlook Data File by using a specialized PST repair tool such as Stellar Repair for Outlook. Armed with highly advanced scanning and repair algorithms, the Stellar PST file repair tool can easily and quickly fix PST file corruption and restore Outlook mailbox data.
The solutions given in this post will help you save time in finding out ways to fix Microsoft Outlook ‘KERNELBASE.dll error’. However, to avoid such a situation in the future, keep a backup of your Outlook PST file. This can help you avoid the last-minute panic of recovering mailbox data. If you don’t have the backup and need quick access to data from Outlook Data File, there are tools like Stellar Repair for Outlook that can help you retrieve mailbox data, with integrity.
