PROBLEM SYMPTOM:

ISSUE 1:

When a user tries to sign into Outlook application using an Outlook.com account, following error message is displayed:

You can’t sign in here with a personal account. Use your work or school account instead.

If the user already had an Outlook.com account added in Outlook Profile, a message “Need Password” is displayed on the Status Bar. When the user clicks on the message and attempts to sign in with his Outlook.com account, he receives the same error message mentioned above.

ISSUE 2:

When a user launches Microsoft Outlook program on Desktop, the program opens and starts loading the profile and after a few seconds, the program stops responding i.e. crashing without showing any error message or information to the user. The user can’t use Microsoft Outlook program to access his email account and send/receive emails.

Once this issue occurs, a log event 1000 or 1001 is recorded in Windows Event Viewer application with following details:

Faulting application name: OUTLOOK.EXE, version: 16.0.15427.20194, time stamp: 0x62e9be45

Faulting module name: mso20win32client.dll, version: 0.0.0.0, time stamp: 0x62e4fd3c

Exception code: 0x01483052

Fault offset: 0x000000000024074d

Faulting process id: 0x1328

Faulting application start time: 0x01d8acfa5984509d

Faulting application path: C:\Program Files\Microsoft Office\root\Office16\OUTLOOK.EXE

Faulting module path: C:\Program Files\Common Files\Microsoft Shared\Office16\mso20win32client.dll

PROBLEM REASON:

According to Microsoft, the problem occurs if a required String value EmailAddress is set to blank or empty under following key in Registry Editor:

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity\Identities

By default, the EmailAddress string should be set to the email ID of the user which is being used by Outlook. Due to a bug or unknown reason, the EmailAddress string becomes empty or blank which starts causing Outlook crashing at startup.

PROBLEM SOLUTION:

Microsoft has provided 3 solutions to fix the crashing and sign in issues. You can try these solutions if you are also facing such kind of issues in your computer:

SOLUTION 1:

Outlook stops responding or causes sign in issues because a built-in Support Diagnostics feature tries to submit an In App ticket. You can turn off this feature to fix these issues.

1. Open Registry Editor using regedit command in RUN dialog box or Start Search box.

2. Go to following key:

HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General

In right-side pane, create a new DWORD with the name DisableSupportDiagnostics and set its value to 1

Close Registry Editor and restart Outlook and now it should load fine without any issue.

SOLUTION 2:

This is the simplest solution. You just need to sign out from Office app and then sign in again which will fix the EmailAddress value in Registry and Outlook will start working again.

SOLUTION 3:

You can also try to manually change value of EmailAddress string value present under “HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Common\Identity\Identities” key in Registry Editor to the email ID which you are using inside Outlook.

It should help you in fixing sign in, crashing or not responding issues in Outlook application.
