Using Classic Outlook on Windows for personal email, calendar, and contact management
Try these steps in order on the same PC where Outlook is hanging at sign-in (dots running under the user ID):
- Sign out of Office completely and sign back in
- Open another Office app (for example, Word).
- Go to File > Account.
- Under User Information, choose Sign out for any accounts listed.
- Close all Office apps.
- Reopen Outlook or another Office app and sign in again with the same account used for the subscription.
- This repopulates the identity registry settings and can fix stuck sign-in.
- Use the automated Outlook account troubleshooter (for business accounts)
- If this is an Office 365 for business account, go to the Outlook account troubleshooter page and sign in with the same account.
- It can automatically fix profile, license, or connection issues such as repeated sign-in or failure to connect to the mailbox.
- If Outlook closes or hangs shortly after opening
- If Outlook opens and then closes or stops responding during sign-in, turn off Support Diagnostics:
- Close Outlook.
- Open Registry Editor (regedit).
- Navigate to:
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General - Create or edit a DWORD (32-bit) Value named
DisableSupportDiagnosticsand set it to1. - Reopen Outlook and try signing in again.
- After Outlook is working normally, remove this registry value later so Contact Support works again.
- If Outlook opens and then closes or stops responding during sign-in, turn off Support Diagnostics:
If the issue persists after these steps, use Outlook on the web (OWA) temporarily to access email while further troubleshooting (for example, with the automated troubleshooter or support).
