Hi,
Thanks for posting in Microsoft Q&A forum.
1,==>I need to make this policy a dynamic device policy and am wondering whether changing this policy type will in any way cause each user to have to reset their password for example / cause any other disruption.
Do you mean to change your assigned group that contains around 100 macOS devices to dynamic group? If yes, after changing the group type, the existing membership may change based on dynamic membership rule we provide. However, per my experience. if one macOS device is already existed in the assigned group before change and continues to exist in the dynamic group afther change, the reset password policy will not re-run on the device and will not cause any other disruption.
2,May we know which device policy you are using to reset the password for macOS device? Is it device compliance policy for macOS\System security\Password policy?
If I have misunderstood anything, please feel free to let me know. Thanks for your time.
Best regards,
Simon
