Right on the heels of our recent TAP program announcement, we wanted to see if there are customers who would like to help us validate migration of modern public folders from Exchange 2013/2016 to Exchange Online (EXO). This is a scenario that at this time we do not support, but plan on doing so. Estimated availability of bits for testing those topologies (subject to change):
Exchange 2013 public folders > EXO: September 2016
Exchange 2016 public folders > EXO: November 2016
In order to participate, you will need to enroll into the above mentioned TAP program.
