I am running Windows 7 x64 enterprise edition with office 2010 x64
version.

For some reason, periodically my outlook.pst file is deleted from my
machine. How do I stop this?

Yes, I make daily backups but I want to stop this
So why does “Windows� delete my outlook.pst file?

Thanks

PS. Yes, I would move to Thunderbird but thunderbird won’t import all
my messages.
Also this time, Outlook lost some of my email addresses.

Are there any other solutions?

PSS. Have a happy new year.
