We use Office 365 for emails. We need to have a shared address book that can be updates by any of the staff.
The addresses are generally for our customers. They need to be easily accessible in Outlook 2016 desktop and also ideally on mobile devices too.
Im guesing for mobile the users they are going to need to use the Outlook app but Im not certain. There is a mixture of IOS and Android devices.
What is the best solution in 2019 as I have seen various approaches online.
