If you use Outlook at work (or probably “no matter what email and contact management system you use at work”) you can simply export the information to a spreadsheet or database or webmail system’s contact management software. I use Outlook at work and – though I don’t need to worry about any long-term career contacts going forward – I do use gSyncIt to synchronize my Outlook calendar with my Google calendar. I could do the same with contacts, but I choose not to.
