Outlook client issue in Windows client
Hi, I have a strange issue with my O365. I can able to access my email from Web portal office.com but when I opened my Outlook client on my windows PC it always says trying to connect and its not...
Just trying to connect and its not asking for credentials. Also if I close and reopen my outlook it gets stuck in the processing screen.
Have had this happen, couple things you can try.
1. Deleting your .ost file in your Profile from "%LOCALAPPDATA%\Microsoft\Outlook"
2. Go to Control Panel, mail and delete and recreate your profile
3. Did you just turn on two factor by chance? If so and you're tenant doesn't have Modern Auth enabled this will prevent Outlook from connecting.

I tried to reconfigure my profile as suggested but no luck. I am getting the attached error. Even I tried to use unencrypted connection with no luck.
- Also use the Connection Status tool. hold down your CTRL key, and right-click on the Outlook systray icon. There will be an option to test connectivity there!
Sorry for spamming but using the mobile so I can’t edit previous posts - Is it possible to Connect on external network like mobile to check if issue remains?
Yes. I can able to access my email from mobile devices bot iOS and Andriod without any issues.
- If its several users, its probably a network issue! Check if any changes ocurred!
Port 443 must be open in firewall
Also check if something changed in DNS
