I am trying to use the Outlook app on an iPhone 5s and an iPad 4 for my Outlook.com email address. I noticed the iPhone and iPad Outlook app both show double contact entries for some, but not all, contacts. Both the Windows 10 People app and if I open People by going to my OneDrive account do not show double contact entries. I am at a loss as to what is happening.
I have uninstalled the iOS Outlook app on both the iPhone and the iPad then reinstalled but the problem persists. I see no way to delete or cleanup double entries using the iOS Outlook app.
Please note I use the same Microsoft ID for my Windows 10 Pro laptop and the Outlook.com account.
Any and all suggestions are appreciated...
The screen shot shows the iOS Outlook app contacts list on the left.
