How to Connect Outlook Calendar with Sally AI

By connecting your Outlook Calendar, Sally can automatically access your meetings and join them without needing a separate invitation (see automated meeting attendance).

After a successful integration, you will see all your scheduled meetings directly in the Sally platform.

Sally supports both Exchange Online (Microsoft 365, cloud-based) and Exchange On-Premise (local server environments).

• Exchange Online: Sign in with your Microsoft account. Both personal Microsoft accounts (e.g. Outlook.com) and Microsoft 365 business accounts (Azure AD / Entra ID) are supported.
• Exchange On-Premise: Connect by entering your server information and login credentials – for organizations running their own Exchange server.

1. Connect Outlook Calendar (Exchange Online)

1.1 Connect a work account

info

Here you sign in with a work, school, or university account (Microsoft 365 / Azure AD). This option is intended for organizational environments where Outlook is managed through Microsoft 365.

1. Open Settings in the left sidebar.

Go to Settings

2. Select “Integrations.”
3. Click “+ Add calendar.”

Open Integrations and click Add calendar

4. Select “Outlook Calendar (Microsoft 365 / Exchange Online)” and click “Connect.”

Select Outlook Calendar (Microsoft 365 / Exchange Online)

5. Sign in with your "Work, school, or university account" and grant the required permissions to complete the integration. After a successful sign-in, your calendar will be synced with Sally.

info

When connecting an Outlook calendar for the first time, an admin login is required to approve the Sally app for the tenant.
After that, all users can connect their calendars normally.

Grant admin consent for the whole organization

If you are a Microsoft 365 administrator, you can approve the required OAuth permissions for your entire organization once. After that, individual users no longer have to confirm the consent screen when connecting this integration.

Grant admin consentYou need to be signed in as a Microsoft 365 Global Administrator. The consent is granted tenant-wide and can be revoked at any time via Entra ID (Azure AD). Admin consent does not give Sally any automatic access to user data - each user still has to connect the integration individually, and an access token is only issued after that user signs in.

6. (Optional) On the Integrations page, click the gear icon next to your connected Outlook Calendar to open the configuration dialog.

Click the gear icon to configure your Outlook Calendar

In the "Configure calendars" dialog you can adjust the sync settings and select which calendars Sally should sync:

• "Sync private appointments": Enable this toggle if you want Sally to also sync your private appointments.
• "Sync only online meetings": Enable this toggle if you only want to sync appointments that contain an online meeting link (e.g. Microsoft Teams, Google Meet, Zoom).
• Synchronized calendars: Activate the calendars whose appointments Sally should sync. Your main calendar and all calendars shared with you are listed here. Up to 5 calendars can be synchronized in parallel per connection. Click "Save" to apply your changes.

Configure sync settings and select individual calendars to sync

7. After the connection is successful, your Outlook calendar meetings will appear in Sally.

Synchronization may take a few minutes. Restart Sally if necessary.

3. Connect Microsoft 365 Rooms

In addition to personal calendars, Sally can also sync Microsoft 365 room calendars. This is useful if you regularly book meeting rooms and want Sally to automatically pick up appointments scheduled in those rooms.

info

Room calendars are loaded directly from your Microsoft 365 tenant. Up to 5 rooms can be synchronized in parallel per connection. Connecting room calendars requires admin consent for the Sally app in your tenant.

1. Open Settings in the left sidebar, select Integrations, and click + Add Calendar.

Open Integrations and click Add Calendar

2. In the Calendar Integrations panel, choose Microsoft 365 Rooms and click Connect. Sign in with an account that has access to the room mailboxes in your Microsoft 365 tenant and grant the required permissions.

Select Microsoft 365 Rooms and click Connect

3. After the connection is established, click the gear icon next to Microsoft 365 Rooms on the Integrations page to open the "Configure room calendars" dialog.

   In the dialog you can:

   • Adjust the sync settings ("Sync private appointments" and "Sync only online meetings") for the room calendars.
   • Activate the rooms whose appointments Sally should sync. All rooms available in your Microsoft 365 tenant are listed here. Use the search field to quickly find a specific room. Click "Save" to apply your changes.

Configure sync settings and activate the rooms you want to sync

4. Once saved, the activated room calendars will be synchronized and their appointments will appear in Sally just like personal calendar events.

3.1 Technical Microsoft Graph permissions for room calendars

Connecting room calendars requires extended Application Permissions on Microsoft Graph. These are granted once by a Microsoft 365 tenant administrator via Admin Consent.

Disclaimer

Read-only: Sally never writes back into the room calendars — neither appointments, attendees, nor locations.

Connection: Granted once by a Microsoft 365 tenant administrator via Admin Consent. After that, token refresh and webhook reconciliation run fully automatically.

Application Permissions on Microsoft Graph

Permission	What Sally needs it for
Calendars.Read	Read all appointments in the connected room mailboxes — including hybrid meetings (on-site + remote) and meetings where no Sally user is invited. Updates and cancellations are propagated via Microsoft Graph webhooks within seconds.
Place.Read.All	List the available rooms of the tenant from the Places Directory (/places/microsoft.graph.room) — so the admin can choose in Sally via toggle which rooms should be synchronized.

Once successfully connected, you now can set whether and when Sally should automatically join your meetings.
