Share contacts in Outlook
How to share a contact list
in Outlook
Outlook can genuinely share a contacts folder, with permissions, and if everyone you work with is in the same Exchange organisation it does the job. The steps are below — along with the conditions nobody mentions until you are halfway through.
At a glance
Outlook shares contacts a folder at a time, to colleagues on the same Exchange organisation. Anyone outside it gets a forwarded copy instead — which is where most teams quietly give up.
- Put the contacts in their own folder first — the folder is the unit that shares
- Permissions decide whether a colleague can read or also edit
- Sharing is a classic desktop and Exchange feature, not offered everywhere
- A forwarded contact group is a copy that immediately starts drifting
- ContactsPlus shares one address book across Outlook, Google and iCloud
The built-in route
How to share an Outlook contacts folder
If you and your colleague are on the same work Microsoft 365 or Exchange account, do this first. It costs nothing and it is a real shared folder rather than a file.
Open People in Outlook
In the classic Outlook desktop app, signed in with a work Microsoft 365 or Exchange account, go to the People area where your contacts folders are listed.
Choose the folder you want to share
Put the contacts in their own folder first. Sharing is folder-level, so a folder is the only unit Outlook can hand to someone else. Right-click that folder and pick the sharing option.
Send the invitation and set the access level
Address the sharing invitation to a colleague and choose whether they can only read the contacts or also change them. The permissions live on the folder, so you can adjust them later.
They accept and the folder appears
Your colleague opens the invitation and accepts it. The folder then shows up alongside their own contacts, under shared folders, without being copied into their account.
For anyone outside the organisation, forward a copy instead
Folder sharing only reaches people on the same Exchange organisation. For everyone else, forward the contact group or the contacts as an Outlook contact or a vCard file — and accept that what they receive is a copy.
Where it runs out
The conditions attached to Outlook sharing
It is a good feature with a narrow footprint. Every one of these is the reason a team ends up back on a spreadsheet.
Same organisation only
Folder sharing runs over Exchange, so it reaches colleagues on your tenant and nobody else. Contractors, partners and a co-founder on a personal account are all outside it.
Not in every version
It is a classic desktop and Exchange feature, and it isn’t offered consistently in the newer Outlook or on the web. Half a team on a different build is half a team that can’t take part.
Permissions are all-or-nothing
Access is set on the whole folder. There is no per-record ownership, so “can edit” means can edit everything in it.
A forwarded group is a copy
Forwarding a contact group is the usual fallback, and it produces exactly the thing you were trying to avoid: a second list that starts going out of date immediately.
The context stays in the mailbox
The folder carries the contact record but not what was agreed, who owns the relationship, or when anyone last spoke to them.
Outlook hides duplicates, it doesn’t merge them
Suppressed from view isn’t the same as fixed, and a shared folder inherits them. Worth clearing duplicate Outlook contacts first.
How it works instead
A shared address book with no tenant attached
ContactsPlus connects the Outlook account you already use, so the shared list is the same contacts — without needing everyone to be inside the same organisation.
One shared address book
Everyone works from the same contacts, whatever mail account they sign in with. An add or an edit by anyone updates everyone’s view in real time.
Roles you control
Owner, Admin and Member roles decide who can manage the team, who can edit shared contacts, and who can only view them — without an administrator having to set anything up.
Shared notes and an owner
Notes the whole team can see, and an assignable contact owner, so the record says who is looking after this relationship rather than leaving it to memory.
Not only Microsoft
Outlook, Google and iCloud accounts connect together, so the colleague on Gmail and the one on an iPhone are on the same list. See how contact sync works.
Clean before you share
Duplicate detection and merging across every connected account, so the team inherits one record per person. See removing duplicate contacts.
It keeps improving itself
Enrichment fills in the details nobody typed, and CSV and vCard export are always there if you want the list back out. See contact enrichment.
Other platforms
Sharing from somewhere other than Outlook?
Mixed teams are the normal case, and each platform shares contacts differently.

Which plan
Shared contacts come with Teams
The shared address book, roles and shared notes are part of ContactsPlus Teams, which adds unlimited contacts and syncs up to 10 accounts, against 5 on Premium. See the full pricing for current plan details.
FAQ
Frequently asked questions
How do I share a contact list in Outlook?
Put the contacts in their own contacts folder, right-click that folder in the People area of the classic Outlook desktop app, and send a sharing invitation to a colleague, choosing whether they can read or also edit. They accept, and the folder appears alongside their own contacts.
Can I share Outlook contacts with someone outside my organisation?
Not as a shared folder. Folder sharing runs over Exchange and only reaches accounts in the same organisation. For anyone outside it, the options are forwarding a contact group or sending a vCard — both of which give them a copy that stops matching yours as soon as anything changes.
What is the difference between a contacts folder and a contact group?
A contacts folder holds contact records and is the thing Outlook can share with permissions. A contact group is a named set of addresses used to send mail to several people at once. You can forward a contact group, but the recipient gets their own copy of it rather than a shared list.
Why can I not find the sharing option in my version of Outlook?
Contacts folder sharing is a classic desktop and Exchange feature, and it isn’t offered consistently in the newer Outlook and the web version. If the option is missing, the usual alternatives are asking an administrator for a shared mailbox, or using a shared address book that doesn’t depend on the mail client at all.
Can I let a colleague edit the shared contacts?
Yes — folder permissions decide whether someone can only read the contacts or also change them. It is coarse though: permissions sit on the whole folder, and they only apply to people inside the same organisation.
Our team isn’t all on Outlook. Does that break it?
It breaks folder sharing, which is the point at which most teams stop. ContactsPlus connects Outlook, Google and iCloud accounts together, so a team split across providers still works from one shared list. Teams syncs up to 10 accounts and Premium 5.
Which plan includes shared contacts?
The shared address book, roles and shared notes are part of ContactsPlus Teams, which also gives unlimited contacts. See the pricing page for current plan details.
One list, whoever they work for.
Give the team a shared address book that doesn’t stop at the edge of the tenant.
