Error message when backing up pst file

[Claire]

I have OL 2007 running on Vista - when trying to back up
pst file get the following error code:0x80070021 The process cannot access
the file because another process has locked a portion of the file.
Can anyone explain this please?

This is why Microsoft does NOT support the use of pst files over a
network......

Eh? Where did the OP mention pst files on a network?

How and with what are you trying to make this backup?

 

[Orland, Kathleen]

Have you made sure that Outlook is actually not running when you perform the
backup? Check your Task Manager > Processes to make sure that outlook.exe is
not still present.

What method are you using to back up your PST file?

Here's an excellent method:

The entire website is excellent. You may want to bookmark it. It will answer
most Outlook-related questions that you might normally have.

So exit Outlook so you no longer have a file handle open on your .pst file.
Then back it up.

Take a look at product BackupMyFolder! and PSTStation Corporate
(http://www.addonmail.com)
These two products will allow you to backup PST files while Outlook is
running (even if PST file is on the network)

BackupMyFolder! is a freeware with functionnality limited to the
backup of PST inside default profile
PSTStation Corporate is a great product that allow you to discover PST
files on the network and then make actions on them like backup,
monitor, compress, ....
