All of a sudden Microsoft outlook 2007 lost its profile

[zillah]

Dear Experts

Today I was fixing networking issue for one of my  client (router and a parallel HP printer).

He is using a desktop with windows XP professional SP3

During my work on his computer I used two softwares which are CClenaer (tune up his computer browser ) and Kyocera Printer Driver Deleter to remove the driver for the HP printer (it was not working properly)

When I finished my work Before I left his office he was able to download a file from his outlook (used as mail client for his ISP) 2007 (means it was working), to test the printer if it prints or not.

I chose an option : “Install windows updates and shutdown”  and I left his office then I received a call from him telling me that his outlook is not finding a file :

Code: [Select]

C:\Documents and Settings\omrion\Local Settings\Application Data\Microsoft\Outlook\tets.pst

When I drove back to his office and checked the file “test.pst” I could not find such a file in the location above(i.e C:\Documents and Settings\omrion\Local Settings\Application Data\Microsoft\Outlook) !!!!!!

For sure I had not touched his outlook when I was working the first time.
 
I felt embarrassed he might have thought that I had damage his outlook.

I checked the Control Panel --> Mail --> Data Files I found those 3 profiles :

Code: [Select]

Name     Path
-------     ---------
Omrion’s email          Outlook.pst in C:\emailfile
Personal Folders        Outlook.pst in C:\omrion\Local Settings\Application Data\Microsoft
I forget name             test.pst in C:\Documents and Settings\omrion\Local Settings\Application Data\Microsoft\Outlook
I am not sure what he had all those three files!!!

The size of the first two profiles (Outlook.pst) are almost 2 GB

The size of test.pst 1 KB hence I deleted it

What should I do to fix this issue ?

He told me that such a problem (he could not recall the exact issue) happened before and someone came to fix that issue for him

I tried to use either one of : Outlook.pst in C:\emailfile or  Outlook.pst in C:\omrion\Local Settings\Application Data\Microsoft

All I can see the old emails till 2009 but not afterwards !!!!!

Can ccleaner or Kyocera Printer Driver Deleter cause this problem ?

How can I fix the problem ? It is an urgent issue please

Regards

I remember a while back dealing with pst's reaching a critical size and causing problems. Your client should be running a backup or redundancy process to protect from lost data. It is possible for the outlook to write to the pst and crash and kill the pst file in which it can be written as a 1k file. Just creating an empty file creates a 1k file. I would suggest implementing a backup procedure for your client either daily, weekly, or monthly backups depending on how critical the data is to protect from deletion.   If your lucky his system might be able to get the pst back by restoring the system back to an earlier recovery date...BUT be sure to save all recent data to a thumb drive and remove it from system. Bring system back to date when his pst is functional, then roll recent data back to the system. Backup the PST's to thumb drive in case ccleaner or driver removal has a strange behavior of affecting the PST, then safely remove thumb drive. You may have to perform your ccleaner and that printer driver removal again as for it will restore what you worked on to remove. Then verify his pst is there and move on.
