Outlook crashes because of a faulty module called KERNELBASE.DLL,<\/em> 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). <\/em>As a result, the most obvious and immediate problem that users face is mailbox inaccessibility. <\/p>

How to fix Outlook Error KERNELBASE.dll?<\/strong><\/h2>

Following are some of the plausible causes behind the Outlook error (after reading through multiple forums<\/a>), and solutions:<\/p>

Cause 1 Faulty Outlook Add-ins<\/strong><\/h3>

Faulty or damaged add-ins can also cause KERNELBASE.dll issue.<\/p>

Solution Disable Add-ins<\/strong><\/h4>

Follow the below-listed steps to disable Outlook add-ins:<\/p>

If Outlook is Accessible<\/p>

If you can access Outlook, try finding the problematic add-ins and\ndisable them by using the following steps:<\/p>

Step 1:<\/strong> Launch Outlook, go to File<\/strong> > Options <\/strong>> Add-Ins<\/strong><\/p>

Step 2:<\/strong> In the window that appears, at the bottom and in front of the Manage section click the Go<\/strong> button.<\/p>

Step 3:<\/strong> In COM Add-Ins<\/strong> window, uncheck the boxes for all add-ins, and then click OK<\/strong>.<\/p>

To check which add-in caused the problem, enable the disabled add-ins\none by one and verify the effect at each step. You will eventually find the\nfaulty add-in this way. Remove it and enable everything else to resume your\nwork.<\/p>

If you are unable to launch Outlook<\/p>

If Outlook is not opening, try the following steps to disable all add-ins:<\/strong><\/p>

Step 1:<\/strong> Open Windows Run dialog.<\/p>

Step 2:<\/strong> Type ‘outlook \/safe’.<\/p>

Step 3:<\/strong> Hit Enter<\/strong>.<\/p>

This will launch Outlook without add-ins and give you an\nopportunity to enable each one-by-one to find the faulty one. If this fix\ndoesn’t work, the problem might not be with add-ins.<\/p>

Cause 2 Problem with User Profile <\/strong><\/h3>

If you can open\nOutlook application and access its data file by logging to a different profile,\nthen likely a corrupt Outlook (user) profile may be causing the error. The profile\ncan become corrupt due to Outlook Data File (PST) corruption. <\/p>

Solution – Create a New Outlook Profile<\/a><\/strong><\/h4>

Follow these steps to create a new Outlook profile:<\/strong><\/p>
