I've read through all of the descriptions for applications on IOS and haven't found any contact export program that will preserve the last modified date on contacts. My employer has contacts stored in an iPhone, iPad and Outlook and has updated different contacts in different places. I wanted to dump everything in to excel and just work from there, but most importantly none of the contact export tools I have tried on IOS contain the last modified date. Without that I would be manually checking thousands of contacts! Any suggestions on apps or techniques?
She is not using iCloud because when she first tried it the contacts were duplicated and notes were lost. We are moving to an exchange server but I have to manually clean up the contacts first.
