Hi, we are using about 50 O365 public groups for SharePoint Modern audience targeting. These groups are not used for any collaboration purposes. Does anyone know the absolute member limit for an O365 group? The MS documentation says "> 1000", but doesn't specify if there is a limit greater than that.
There is no "hard limit" afaik, and certainly not 1000, as Teams now supports more. The limits referred to in the documentation apply to different functionalities that might be affected after the group reaches certain size, so they're more of a recommendation.
