MS Outlook (365) Stops working

Happens every few days. Even clicking on the exe doesn't work. Do quick repair and all fixed until the next time.
Driving me crazy. Any suggestions welcome

general things to try
try outlook in safe mode : outlook.exe /s . If that works, remove (not disable) outlook comm addins (in settings)
Full repair (not quick repair)
Uninstall & re-install
delete the outlook profile & start again : resetup
set Outlook to uncached mode . If you have ALOT of email (say 15G + ) , that sometimes causes issues with syncing/downloading from 365. If uncached fixes it, it often means OST or profile corruption

Uninstall any 3rd party AV or internet security
run a full surface scan on the HD
check internet speed, check for micro outages in internet .
If using wifi , try connecting via ethernet cable

To add to a previous post, I also recommend you to check it for viruses and restore a version of your outlook that worked fine. Also, I think you'll need a backup option for it as well. Because that sounds like a potential data loss situation to me.
