Best possible methods to Fix Outlook Error Code 0xc0000005

To fix Outlook Error Code 0xc0000005, first, reboot Outlook in Safe Mode (Win + R, type outlook.exe /safe). If Outlook opens normally, disable add-ins via File > Options > Add-ins. Next, use the Microsoft Office Repair Tool (Control Panel > Programs > Programs and Features > select Microsoft Office > Change > Repair). Update Windows and Outlook to the latest build. If it keeps on occurring, create a fresh Outlook profile (Control Panel > Mail > Show Profiles > Add). The System File Checker also helps in fixing corrupted system files (sfc /scannow in Command Prompt as admin).

Manual repairs do not fix issues like deep system corruption, malware, or hardware failure (i.e., faulty RAM). Recreating profiles will eliminate personal settings, and fixing Office will not always cure all compatibility issues.

If manual processes don't resolve the issue, you can use professional tools for recovery of Outlook data files and error fixing.
