Upon using MS Office at work, I was given a large Spreadsheet of people I have to call. I was given user ID numbers but no Phone Numbers and only a few emails. I looked to see if I could find an easy way to have those user ID's somehow be the key for getting phone numbers from my Outlook contacts. The tedious copying of an ID number (which will always give one result) into my address book 400 times then copying their phone number just to put it back into the spreadsheet could be much easier due to the uniforn nature of the contact field. I compare it to the way music files are tagged and read. The metadata for each song has an artist, title, album, etc but the filename doesn't have to be anything important. I wouldnt know where to start coding, but using a spreadsheet for contacts is a popular practice and more tools for autofilling would be useful.
