We really would like the possibility to enable Office 365 Groups for campaigns.

Working in campaigns is typically a team effort in our company. Using Office 365 groups for this type of collaboration would be great since people for many disciplines are involved.

We were very glad to hear that with CRM 2016 we could enable the Office 365 integration for any entity. We were very sorry to find out (and got confirmed by Microsoft Support) that on the campaign entity in CRM we cannot enable the integration with Office 365 Groups.
