Hi @SD
Thank you for reaching out to the community forum!
By default, Each Microsoft Entra tenant is limited to 500 dynamic groups using the memberOf
attribute. The memberOf
groups count toward the total dynamic group member quota of 5,000, Each dynamic group can have up to 50 member groups.
Even with custom dynamic rules in place for a Dynamic Security Group, these limits of 500 dynamic groups and a 5,000-group member quota still apply, if you considering that the Microsoft source is not correct could you please share the documented information or result of your research on the custom dynamic rules this will help us and others in the community as well.
I hope the information above is helpful.
If you have any question or concern, please feel free to let us know.
Thanks,
Akhilesh.
