What Is a Microsoft 365 Shared Contact List?
A single, centrally managed address book that stays instantly updated on every staff phone.
A Microsoft 365 shared contact list (often built from your Outlook or Global Address List) gives your organisation one reliable source of truth for company contact details.
Instead of storing contacts separately on each device — or relying on manual exports from Outlook — the list is managed once and automatically synced to staff iPhones and Android devices.
With a Microsoft 365 shared contact list, every team member sees the same accurate contact information — always up to date on iOS and Android.
This helps prevent:
- • Outdated company contacts stuck on individual phones
- • Staff creating their own inconsistent contact lists
- • Missing or duplicated contacts during onboarding or offboarding
- • Security issues caused by contacts being edited or deleted on devices
