Contact photos do not synchronize between Outlook for Mac 2011 and exchange or Windows versions of Outlook.

Hello, I installed Office for Mac 2011 and when it synced the contacts (through Exchange), most of the contact photos now no longer show in OWA or in Outlook 2013 from my Windows PC's. They are not lost: In Outlook 2013 (for windows) they appear instead under "Notes", in the form of a thumbnail jpeg. On my Mac, however, the photos show up correctly. None of my windows accounts (e.g., windows phone) now show any photos any longer. I tried some troubleshooting: I deleted all my contacts from everything, and imported them back to Outlook for Mac and synced them, but the photos still show only under "notes" in the Windows accounts. On my Mac, however, the photos show up correctly.

How can I solve the issue? I see the same problem reported by other people, but I am not aware of a resolution. I have posted this questions in Windows forums, etc., but I did not get any helpful advice yet.
