Unable to save contacts in Outlook 2007

[robin45]

Hi,

I just purchased a new computer with windows Vista and Office 2007. I've been totally frustrated because you can not save the email address for a new contact. I copy and paste or type the email address and as soon as I tab out, or save the address disappears. I have checked and searched for my optiions the 'net and can not understand what is happening. I don't know how to use Outlook and save a contact! Can anyone help me?!

Create a new PST file in Outlook and have a backup of the old PST files and implement a SCANPST file and open the PST and drag and drop all the elements in the new PST file.

Created a new profile :
a. Add your exchange connection with cached mode on and a new clean OST
b. Create a PST (new clean) file
c. Set the local PST file as default
