Microsoft 365 is Microsoft’s cloud platform with Outlook calendars for people as well as room and resource mailboxes. With the integration, anny connects your resources directly with these calendars: a two-way synchronization keeps bookings and appointments up to date on both sides. With Microsoft 365 you can, inside anny:
  • Couple room, resource, and person calendars of your organization with anny resources (real-time two-way sync)
  • Automatically take over calendar appointments as blockers or bookings in anny and avoid double bookings
  • Automatically create Teams meetings with an invitation to customers for bookings
The integration is aimed at organizations that manage their Microsoft 365 environment centrally: an administrator connects the entire organization once, without individual employees having to sign in. For connecting individual personal mailboxes, there is the personal Outlook integration; you find a comparison in the overview article Calendar integrations.

​
Typical use cases

​
How the Microsoft 365 connection works

The connection is established at the organization level. An administrator of your Microsoft 365 organization clicks Authorize in anny, signs in to Microsoft, and grants consent for the organization (admin consent). After that, anny can access the calendars of users as well as the room and resource mailboxes. Individual employees do not have to sign in. anny accesses only the calendars you explicitly link with a resource in the settings; the main calendar of the selected account is synced in each case. If you revoke consent in the Microsoft admin center, the integration deactivates itself and notifies the admins. Synced is the period from today up to about 12 months ahead; anny extends this period automatically. Past appointments are not imported. After activation, anny first imports all future appointments and bookings, after which changes arrive continuously in real time.

Connect Microsoft 365

​
Requirements

Before you connect Microsoft 365, make sure you have the following:
  • A Microsoft 365 organization with Exchange Online mailboxes (cloud, not on-premise)
  • Administrator rights in Microsoft 365 to grant consent for the organization
  • Admin rights in your anny account
  • The calendars you want to connect already exist (for example, room mailboxes for your rooms)

​
Set up the connection

1

Create the integration

Open Integrations from the menu bar and select Microsoft 365.
2

Authorize

Click Authorize. You are redirected to Microsoft: sign in with an administrator account of your organization and grant consent. After that, you are automatically returned to anny.
3

Create connections

In the Calendar synchronization settings panel, define which calendars are coupled with which resources:
  1. Click Add.
  2. Under Choose the resource to synchronize:, select the anny resource.
  3. Under Microsoft calendar, select the account (person or room/resource mailbox) whose calendar should be synced. Using the search, you find accounts by email address.
  4. Adjust the other options if needed (see Settings & options).
  5. Click Confirm and repeat the steps for further calendars.
4

Activate

Activate the integration via the toggle in the top right. anny checks the connections and starts the initial sync.
Once the integration is active, all future appointments and bookings are reconciled and changes are synced continuously in real time.
After creating a connection, use the Error diagnosis action in the rule table. Among other things, it checks whether the calendar is reachable, whether automatic replies are active, and whether other integrations or ICS imports overlap with the calendar.

​
Settings & options

Each connection (row in the table) has its own settings. To edit them, the integration must be deactivated. In the booking view, the Calendar synchronization panel shows the source, the connected calendar, and the sync direction for each synced booking. There you also find the link Show event in external calendar and the button Re-sync calendar.

​
Limitations

The Microsoft 365 integration does not support:
  • On-premise mailboxes: Only Exchange Online calendars in the cloud work. Unreachable mailboxes are marked with “Microsoft calendar not reachable” and skipped.
  • Sub-calendars: The main calendar of the selected account is always synced, no additional calendars of a mailbox.
  • Past appointments: Only appointments from the day of activation onward are imported; older entries remain untouched.
  • Duplicate connections: Each calendar can be used in only one connection. If a resource is additionally connected via a personal Outlook integration, the integration cannot be activated.
  • Editing while active: Connections can only be changed while the integration is deactivated.

​
Disconnecting

If you deactivate the integration, synchronization stops immediately; already synced appointments, blockers, and bookings remain on both sides. If you delete the integration, anny removes the synchronizations it created: appointments created by anny are deleted from the Microsoft calendars, and blockers and bookings created from appointments are removed from anny. When deleting, you choose whether this applies to Only future synchronizations or All synchronizations (including past).
You can do both under Integrations: deactivate via the toggle in the top right, delete via the three dots → Delete.

​
FAQ

The Microsoft 365 integration connects the entire organization: an administrator authorizes once, after which any person and room calendars of the organization can be coupled with resources. With the personal Outlook integration, by contrast, each person signs in with their own account. More on this in the overview article Calendar integrations.
All accounts of your Microsoft 365 organization that have an email address: users as well as room and resource mailboxes. The main calendar of the account is synced in each case. In the Microsoft calendar selection, you can search by email address.
Yes, but without content: appointments marked as private or confidential always appear in anny with an anonymous subject. With the option Anonymize appointments, you can additionally anonymize all appointments of a connection.
anny deletes the associated appointment in the Microsoft calendar. Conversely: if an appointment in the calendar is deleted, anny removes the blocker or cancels the booking created from it.
Booking changes from anny are transferred immediately. Changes in the calendar are reported by Microsoft via push notification, usually within seconds. With very many changes at once, Microsoft can throttle the connection briefly; anny catches up on the changes automatically afterwards.

​
Troubleshooting

Usually the mailbox is not reachable, for example because it is on-premise or no longer exists; the connection is then marked with “Microsoft calendar not reachable” and skipped. Deactivate the integration, check the connection via the Error diagnosis action, correct the calendar, and activate the integration again. On activation, anny resets the error and tries again.
The authorization became invalid, for example because consent was revoked or restricted in the Microsoft admin center, or Microsoft permanently refused the push connection. The affected admins receive a notification with the reason. Click Authorize, grant consent again, and reactivate the integration.
The calendar or resource is connected multiple times, for example additionally via a personal Outlook integration or an ICS import/export of the resource. The Error diagnosis action shows such overlaps. Remove the duplicate connection and then sync via Re-sync calendar in the affected booking.
Check whether the booking belongs to the booking options chosen in Select booking options and whether it is confirmed or requested; declined and cancelled bookings are not transferred. Bookings that are more than about 12 months in the future are only synced once they move into the sync period.
