I am trying to migrate from Exchange 2013 on prem in a hybrid environment to 365. I tried the little upgrade icon for the distribution groups to 365. It shows no groups eligible for upgrade. I opened a support case with MS and the engineer set up an environment for testing and found the same issue. Why do they have an icon that doesn't let you upgrade from on prem to 365 distribution groups. The MS engineer said the only ones that showed up in his test environment as an eligle upgrade to 365 were ones he created in 365 - which IMHO makes the upgrade to 365 completely inane. That is like saying would you like me to paint your brand new blue car to the same color blue?
