I have tried every option to export the IPTC Creator information with the files from Lightroom. It shows the copyright information correctly, but does not take address, phone number and other contact information.
This time I am using a PC, Windows 7, LR CC and Photoshop CC.
How are you exporting the Files from Lightroom as? (Jpg or DNG)
I just tested the same and it is working as expected.
Are you able to see the IPTC metadata exported by Lightroom in the new File?
I tested this with both Photo > Edit In and with File > Export followed by opening the file in Photoshop. In both cases, the IPTC creator contact information showed up in Photoshop's File > File Info window.
If you're using LR's File > Export, make sure that in the Export options in the Metadata section, you do not have Include: Copyright Only selected.
If that doesn't help, then provide exact details of how you are getting the file from LR into Photoshop.
