Create Group

See more Microsoft Group Examples

Create a new group as specified in the request body. You can create one of three types of groups:

• Office 365 Group (unified group)
• Dynamic group
• Security group

This operation returns by default only a subset of the properties for each group. These default properties are noted in the Properties section.

See https://docs.microsoft.com/en-us/graph/api/group-post-groups?view=graph-rest-1.0 for more information.
