Outlook Desktop won't open

Copper Contributor


I have installed office 365 on my computer for work and uni using those logins. Every application is fine except outlook that won't open telling me that it "can't log on".

Error messages below.

I have tried:

- Repairing office 365 via installed apps

- Repair outlook data files using SCANPST

- Run resetnavpane


Any other ideas?



Error 1. When I first open the program, I am greeted with this. Network connectivity is fine. I have checked access in firewall. Only running Windows Defender as defence/firewall program.



Error 2: I click OK on the first and get this. System resources are absolutely fine. I don't have much open. I have tried this with nothing open whilst watching Task manager. Nothing out of the ordinary.



Error 3: I click OK again, the Outlook window behind closes and I get this. Not sure what to check here. Click OK on this and that's the last of it.
