I am looking to identify the registry keys and values that need to be updated, to change the default Outlook Address Book in Outlook 365.
In the testing that I have done for a user using a registry snapshot tool, some of the relevant entries appear to be:
When I capture these key/values on an initial domain\user; I can change the selected Outlook Address Book as I wish.
However when I then try to apply the updated registry settings to a different domain\user; that user's Outlook Address Book settings are not being updated.
So I'm thinking that there must be additional registry keys/values that need to be captured.
