Microsoft Office 365 - OUTLOOK

Couple of days ago I started to get Not Responding just after opening Outlook.  Now I can't even load Outlook Repair PST files or create new PST of new Profile.  Each time get error Outlook Not Responding and or error code 0x800040401.  Nothing works

Also if I try to create new Profile it says my Personal details are incorrect but copied them from my email supplier. 

I need access to my PST file to get very important contacts and emails,  Please help? TIA

    Try running Outlook in Safe Mode and use Microsoft's "Inbox Repair Tool" to scan and repair the PST file.
