I've received quite a few questions over the last couple of weeks asking how to stop Outlook from running when the computer is rebooted.
Outlook has recently started opening when the computer boots. I looked in the startup menu and task manager and Outlook is not listed anywhere. I don't want it to automatically open. How do I stop it?
While the usual place to look is in the startup menu, you probably won't find an Outlook shortcut there. It could be caused by one of two things, neither of which is obvious or in the start up menu, task manager, or msconfig.
- You are using Windows 10 and did not close Outlook before shutting down the computer.
- You have a utility that uses Outlook data. The utility loads at startup and loads Outlook so it can access the data.
If you use Windows 10, you may be the victim of a Windows "feature" to reload any program that was running when Windows shut down. While this feature is nice when Windows reboots to install updates, it's annoying when it does it after every reboot.
Until Microsoft adds an option to not reopen the programs that were running when it shut down, you'll need to close the Outlook and other programs before shutting down the computer or rebooting.
When it is fixed, it will be controlled by the option in Settings > Accounts > Sign-in Options to finish setting up apps after logging in. While this option is in older builds, it apparently is not working in older builds. Slide it to Off to keep Outlook and other apps from reloading when Windows boots.
You can use a workaround until Microsoft fixes it in a future version. Right-click your Desktop, choose New, Shortcut. Use this command as the target:
%WINDIR%\system32\shutdown.exe /s /hybrid /t 0.
If the cause is another program accessing Outlook data, you'll need to check the programs that load at startup. Sync utilities that sync Outlook data to other computers or with your smartphone would be the most likely suspects, but any application that accesses Outlook data could be responsible.
