I have two accounts in my Outlook profile, and both have a 'Contacts' folder. They are easily distinguishable in Outlook itself (desktop version) which shows the account name, but when using external app (Ring Central to be exact) the name of the Address Book is used , which is 'Contacts'in both cases. I have tried to rename the Address Book (not the folder) in the folder properties but the change does not 'stick' and it reverts to 'Contacts' I have 'owner' permission on the folder. Thoughts anyone?
