Export-Import .pst file problems


Outlook version
Email Account
I upgraded to Win-10 / Office 2010 on a new machine, and am moving over 1500 contact records critical data for my business from Win-7 outlook 2007. There are 3 user defined fields and they do not appear in the exported file, I googled this issue and it seems outlook does not export UDF's. So, I did some testing, inserted a NAME field into my existing CONTACTS records folder). You can rename this to whatever you want and I did, and this interestingly, now shows up as a UDF field which does not export either. SO, I did even more testing, deleted that column I re-selected the NAME column, did not change the name of the NAME column , inserted that, added some data, exported and THAT field does not show up either, so WHAT exactly is going on? I viewed my .PST file directly with a .PST viewer, EXTREMELY HANDY for t his. WHAT are the rules here for exporting fields in Contacts folder? This is a big deal, I have a large contacts file with column data I CANNOT MIGRATE / EXPORT. Big problem.

UDFs do not export. Or import.

You cab use the user1 - user4 fields for the data (use a macro to move the data to and from those fields) or use a macro to export all fields. But... you don't need to. If you have the data in a pst in 2007, copy the pst to the new computer. Or export the contacts to a pst. Moving an existing pst to the new computer has a number of advantages, including you'll keep views, rules, categories, and custom forms

Why not? Moving the contacts as outlook contacts is the most efficient method and will preserve the fields and their values.
