The total length of the body of your advanced rule cannot exceed 2048 characters.
Note the use of the "[" and "]" at the beginning and end of the list of values.
If a user or device satisfies a rule on a group, they are added as a member of that group.
If you use it, you get an error whether you use null or $null. The correct way to reference the null value is as follows: Extension attributes and custom attributes are supported in dynamic membership rules.For example: assigned Plans is a multi-value property that lists all service plans assigned to the user.The below expression will select users who have the Exchange Online (Plan 2) service plan that is also in Enabled state: - if you do, it will be interpreted as a literal string value.The three parts are: A complete advanced rule looks similar to this: (left Parameter binary Operator "Right Constant"), where the opening and closing parenthesis are optional for the entire binary expression, double quotes are optional as well, only required for the right constant when it is string, and the syntax for the left parameter is user.property.An advanced rule can consist of more than one binary expressions separated by the -and, -or, and -not logical operators.When the manager's direct reports change in the future, the group's membership will be adjusted automatically.
