Upgrade problem from 2003 to 2007

[Dee]

There seems to be a compatibility issue between the OL 2003 and OL 2007 and I
think it is the way I upgraded. OL 2007 is very unstable - crashes
constantly, freezes, comes up with an error message "The document template is
not valid" whenever I try to create an email, open an email, create an
appointment, a task etc. I also do not have an address book, even though I
imported my contacts. I understand you have to create a link so that Outlook
will use your contacts as your address book. I have followed the steps set
out by Microsoft but my Contacts is greyed out and I can't select it to link
as my address book. Something is seriously wrong with it.

Dell have told me I need to use the Import/Export Wizard to transfer my
settings across (this was 12 months ago I did the initial transfer using
Files and Transfer Wizard in XP). I run Vista Home Premium on this new laptop
with Office 2007.

Can I delete everything, do a fresh install of 2007 and create my contacts
from scratch and set up my email addresses again?

If you upgraded from 2003 to 2007 you shouldnt need to have done anything.
2007 should have connected with your origonal data file, unless you opted to
create a new one, thus your mail & contacts would have been in place.

Does the set of Personal Folders you are currently using contain your old
mail?
If you search to include hidden for *.pst what named files does it return
and the sizes & date stamps?
