<p>After investigation, Microsoft has confirmed that they&#8217;re aware of this issue. Microsoft discovered that the error occurs when the <em>EmailAddress</em> registry string value under the Office identity is missing.</p>
<p>The Redmond giant presented a registry instance that causes Outlook to crash or stop responding.</p>

<p>The EmailAddress string key is located at the following location:<br />
<strong><em>Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity\Identities</em></strong></p>
<p>As Microsoft continues to work on a fix, the recommended mitigation is to sign out of the Office and then sign back in which will repopulate identity registry settings.</p>
<p>If the issue persists, you can try to disable Support Diagnostics which will turn off the option for submitting In App ticket using Help, contact support along with the path of the feature that causes the Outlook to crash.</p>
<p>In order to disable Support Diagnostic please change the <strong><em>DisableSupportDiagnostics</em></strong> value to <strong>1</strong> at the following path:</p>
<p><em><strong>HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General</strong></em></p>
<p>You can also try to manually set the email address value for the <strong><em>EmailAddress</em></strong> key at:</p>
<p><strong><em>Computer\HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity\Identities</em></strong></p>
