Outlook 2010

I have one domain workstation that Outlook 2010 will stop responding when: the user tries to move emails from the inbox to a .pst folder. the .pst folder is located on the SAN. I just tested the move. moving 5 emails to the .pst file took about 5 minutes.
We are using Exchange 2010 and server 2008 DC's

.PST files should NEVER be stored anywhere except on the local users Hard Drive. This is a documented fact from Microsoft themselves.  The reason?
Outlook uses file level access methods to access a .PST file that are not suitable or compatable with network storage. Its a simple fact that lots of people ignore and just brush off as "Microsoft Speak". Its a fact and evidenced in lots & lots & lots of cases where people have all kinds of issues with .PST files purely because they insist on using them on network shares etc.

Keeping the .pst on the network is the only way right now I can back them up to tape. If the local hard drive failed with no backup I would get fired.
This is the same user moving email from her Inbox to a .pst file, same PC.
Some user have large inbox and .pst files and some users small amount of email/pst.
creating new pst file is no issue/just moving mail.

Call me stupid if you like but.....

Why do you have a .PST file at all?  Your moving emails OUT of exchange, on your SAN to be stored in a .PST file, ON THE SAN? Performance of a .PST file on any form of network device is well doccumented to be appalling in performance, slow, unreliable, locks left, affects ALL other network access from the machine etc...

So as the BIGGEST issue, well doccumented, in using .PST files on a network device is SPEED, why bother?

Why is the data not just in your exchange server?  What version of Exchange do you use?

P.S.

Talking of getting fired, what happens when......

A common issue with storring .PST files on netowrk storage is that of corruption of the data. This is not normally evident until some months after the corruption has occured and a user (Normally CEO or other High ranked official) needs to access that ONE VITAL EMAIL!

Corruption inside a .PST file will not always be evident just by opening the .PST in outlook. A lot the internal mail data can be corrupt but the file will still open and seem fine.....
Neil Russell

And I am giving you advice on the issue.  You are asking why performance could be so dire. The simple fact is that a .PST on a network is unsupported and the biggest issue you can have is that of speed and general network degredation.

What happens if you copy that same .PST file to the local HD and try the same move of data?
