Try this in order:
- Disconnect all external devices from the laptop, including USB devices, printers, external drives, keyboard, and mouse.
- Press and hold the power button for 30 seconds to force the laptop to shut down.
- Wait a few minutes, then turn the laptop back on.
If the laptop still stays stuck on Restarting, disconnect the AC adapter and let the battery drain completely as a last resort.
For the Outlook issue after the PC starts again, these are the supported next steps for classic Outlook:
- Run Windows Update until Windows shows You’re up to date.
- If Outlook opens, start it in safe mode:
- Press Windows key + R.
- Type
outlook.exe /safeand select OK. - If Outlook works in safe mode, disable COM add-ins from File > Options > Add-ins > COM Add-ins > Go.
- If Outlook still hangs or will not reopen, repair Office from Control Panel > Programs and Features > right-click Microsoft Office 2016 > Change.
- If needed, repair Outlook data files with the Inbox Repair Tool.
- If the issue started after Windows updates and the Outlook profile uses POP or PST files, install all available Windows updates until Windows reports You’re up to date, because a known issue was fixed by Windows.
