Sync people from Microsoft 365

Let your Microsoft 365 directory create and remove Offision accounts by itself, for everyone or just for the groups you choose. About five minutes to set up.

Updated 16 Aug 2026

With user synchronization on, your Microsoft 365 directory is the source of truth for who exists in Offision. New starters appear without anyone adding them, and leavers disappear without anyone remembering to.

What to have ready

  • The Microsoft 365 integration already connected
  • A decision about scope: everyone, or only certain Microsoft 365 groups
  • The Offision user groups new people should land in

1. Open user synchronization

Open Integrations

Open the Microsoft 365 tile, then on the integration card choose the Synchronize users row. If synchronization has never been on, the screen is an empty state with a single Turn on user synchronization button.

Turning user synchronization on for the first time.

2. Choose what to sync

ChoiceWhat arrives
Sync all usersEvery person in the directory, no groups
Sync all user and user groupsEvery person, and the group structure with them
Sync specified user group’s usersOnly the members of the Microsoft 365 groups you pick

Pick Sync specified user group’s users when Offision is for part of the organisation rather than all of it. It is much easier to widen the scope later than to remove several thousand accounts that should never have arrived.

3. Check the preview before saving

As you change the settings, Offision counts what they would actually bring in and shows it as Will sync N users and M groups, with a row of faces. This is a real dry run against your directory, calculated from the unsaved settings in front of you.

Read it. A count far larger or far smaller than you expected means the scope is wrong, and this is the last moment it costs nothing to fix.

4. Set where new people land

Default native user group decides which Offision user groups a newly synced person joins. Everything that keys off user groups — which rooms someone may book, what they can see — follows from this, so a new starter with no group may be able to sign in and book nothing.

If your organisation uses card numbers for check-in, set the card number source here too, so cards arrive with the people rather than being typed in later.

Save, and the first sync runs.

5. Check it worked

Open the Synchronized users page in the same screen and confirm the people you expected are there, in the groups you expected. Re-sync runs it again on demand rather than waiting for the schedule.

Then check the other direction: someone who is not in scope should not be listed.

Sync is a mirror, not an import

This is the part worth understanding before you turn it on.

Turning synchronization off does not delete anyone. The people already synced stay in Offision; they simply stop updating from Microsoft 365. Offision says so when you turn it off, and the warning is worth reading rather than clicking past.

People added directly in Offision are unaffected either way — see Add people to Offision.

When it goes wrong

What you seeUsual cause
No Synchronize users row on the cardThe integration is in a mode that cannot read the directory
The preview will not loadThe directory permissions were granted but consent was not, or Microsoft has not applied them yet
Far fewer people than expectedThe scope is set to specific groups, and they are smaller than assumed — or nested groups are not what you thought
People arrive but can book nothingNo default user group is set, so they land with no permissions
Someone came back after being deletedThey are still in a synced group in Microsoft 365; remove them there, not here
Everyone disappeared at onceThe scope changed to a group that is empty or unreachable. Fix the scope, then re-sync
