Backing up email on Outlook 2007 fails

I find an error signal whenever I want to back up Email. I use Win 7 Professional OS, Microsoft Office 2007, along with this 2011 (including latest update available). I get the following error message:

Error
Failed to back up file or folder Microsoft Office
Outlook/Profiles/Outlook/2FC8E0769E8B5E4399F 59D E D4AO9FDB7/".
Retry Ignore Cancel
I checked the knowledge base and it stated that this error signal happens only when Outlook is trying to run but for me it happens all the time. Also knowledge base showed that with this error signal, no private Folders in Outlook can be backed up.
I just bought a back up program, and not being able to back up a large amount of my Email is annoying. I try to back up all my PST files in the data backup part of this 2011.
It will mean that I would receive my messages in private Folders back in the event of a collapse, but still one should be able to back up Outlook.
Dragging PST files from a data file would need resetting up an email ID, re-starting all my settings and bringing the PST files. My last irritation is that I am not able to get phone, email or live chat hold from Acronis without giving them money.
Need a solution to fix this problem. Thanks a lot.
