Hello,

I have Windows Vista Business with Office 2007.

I mapped network folder as my Z: drive. On this drive i have several
folders. In one folder named "Mail" I have my outlook.pst file. This
work correct. Then I right-click on folder "Mail" and choose "always
available in offline mode" (I translate from different language). Vista
synchroniznig files. When I reboot computer without network connection
sometimes I don`t see my mapped drive Z:, but the most often i can see
my Z: drive and i can go into "Mail" folder. However i try copy my
outlook.pst file (to dektop) i get an error: "Error 0x800710FE: This
file is at present inaccessible - can not him use on this computer."
(this is translation).



You are running a big risk of frequently and quickly corrupting your pst
file both by using it from a network drive as well as in off-line mode.
Connect to the network drive and copy it to your HDD. Use it from there.
If it needs to be on a network drive for backup purposes, create a batch
file that will copy it there when you close Outlook.

Why is risk using pst file from a network drive?
I have used for several years this way on tens computers and I had never
problems.



Then you've been very lucky. Outlook needs constant read/write access to the
pst file - if there is a little blip in the network connection while that is
happening then the pst file will corrupt.
