Understanding profile picture synchronization in O365 Hybrid Environment

TonyRedmond has an excellent discussion of how sync works between the various directories in his Office 365 For It pros book, see http://exchangeserverpro.com/ebooks/office-365-for-it-pros/. It it he refers us to some additional info at https://threewill.com/user-photo-sync-behavior-in-office-365/

1. talk to the people setting that requirement to find out exactly why they feel this is necessary. What is the value to the business? enforcing this requires some time and effort which may be better spent on other activities.

2. it starts off with a single source. i.e., Azure AD, but then the images get replicated to service specific directories.

3. no, not possible.

I'm not going to copy out all of the good info from his book because I paid for it and he deserves more sales :) It is well worth the money.
