Create a dynamic group in Yammer

Dynamic groups update automatically as people join, leave, or move within your organization, whenever the user's Azure Active Directory attributes are updated. Dynamic groups work well for large organizations where people change teams, roles, and locations often. Dynamic groups can be created based on a variety of attributes, including role, geography, and department.

Only Office 365 connected Yammer groups can be set up as dynamic groups. This means you must be enforcing Office 365 identity in Yammer, and your Yammer network must have existing Office 365 connected groups.

Q. Are there limits to the number of members in dynamic groups?

A. Yes. Dynamic groups in Yammer have a limit of 100K members. After 100K members, new members will not be synced to the group in Yammer.

Q. Do users experience any differences in Yammer when using a dynamic group?

A. Yes. Groups with dynamic membership do not have the Join and Leave buttons in the top navigation. Instead, users either see Member for dynamic groups to which they belong, or Reserved if they are not members of the group.
