OUTLOOK HAS STOPPED WORKING

Outlook has suddenly stopped working. I am a small businessman and need my email service. Impossible to contact a human in Microsoft Support. Any advice please?

In what sense has it stopped working, and did you try the Web alternative too (outlook.com)?

Which version of Outlook do you have? The classic Outlook for Windows? The new Outlook?

Or do you have Outlook for Mac?

Hello, thank you for reaching out to Microsoft Q&A.

To better understand the issue, could you clarify what you mean by "stopped working"?

Are you unable to sign in to your Microsoft account, or is the Outlook application itself not opening or responding?

Also, are you using a personal Outlook/Microsoft account or a work/school (business) account?

Are you able to sign in with your Microsoft account here and send/receive emails normally?

I am also experiencing issues. I attempted to send an email out to my staff and it hung up with a blank screen and just showing it was pending. I rebooted my system went back in. I’m still having issues with being slow and it’s not my laptop. This is happening on several different platforms.

My outlook is down as well. It just simply won't open. There are no .exe's running in the background for it, I notice the exe pop up then it just disappears. Tried uninstalling and re-installing and it still doesn't work.
