Hi,

Delete an OST file. Does not get deleted.
C:\Users\Name\AppData\Local\Microsoft\Outlook\outlook.ost

I used process killer,Unlocker and many tools but none works . Even when the outlook is closed i cannot rename/Move or delete the file.

Use process monitor and/or file monitor to find out what is keeping the file open.  If that fails, boot to a BartPE boot CD and delete it from there (I would suggest renaming - even running a CHKDSK C: /R before doing that).

1.Ensure that the file doesnt have read only permissions.
2. Close outlook and then go to the task manager. in the process tab, if you have outlook.exe still running, end the process.
3. Try to delete the file then.
4. If this doesnt work, rename this file and then restart outlook. it should automatically create a OST file.
5. Once that is created, try to delete this old file

Is Exchange Server being Used?
If so, Need to make sure that Cached Exchange Mode is off when you delete the File.
Tools>Account Settings>Open Users Account Details
Right under Exchange Server Name
Untick the Box that says "Use Cached Exchange Mode"
Apply and Close Outlook

Now delete the ost

In my case I could not  delete the ost file and could not open outlook to untick cached mode. Renaming the file resolved the issue.
