Microsoft 365 Calendar

What it does

Microsoft 365 Calendar works with your booking page.

• Busy timesSellAnyBiz checks when you are busy in your Outlook calendar, so a guest can only pick a time you are free.
• Booked callsA call a guest books is added to your Outlook calendar with the guest invited. If the call is moved or cancelled, the event follows.

Whose connection is it?

The connection is yours. It is saved for you, in the workspace where you connected it.

• Your teammates do not share this authorization. Each person connects their own calendar.
• Any member of a workspace can connect. There is no step for an owner or an admin.
• A booking page uses only the connection made in its own workspace.

What SellAnyBiz asks Microsoft for

SellAnyBiz asks Microsoft for three things.

• Read and write your own calendar. SellAnyBiz uses it to see when you are busy, and to add, change and delete the events for booked calls.

  Sent to the provider as Calendars.ReadWrite

• Keep the connection working, so you are not asked to sign in again every hour.

  Sent to the provider as offline_access

• See your basic profile and mailbox address. The address is also what SellAnyBiz gives Microsoft when it asks about your busy times.

  Sent to the provider as User.Read

The first permission covers your whole calendar, which is wider than what SellAnyBiz does with it. From your existing events SellAnyBiz uses only the times you are busy, and it writes only the events for booked calls. It never reaches anyone else's calendar.

How we handle your data: our Privacy Policy

Good to know

• A personal Microsoft account cannot be used. Microsoft answers the busy-time question only for work and school accounts.
• A booking page reads one calendar. Google Calendar is the other choice.
• Microsoft sends the guest Outlook's own invitation, and its own notice when a booked call is cancelled.

Individual and team use

The signed-in person’s calendar is used. This is not a Microsoft 365 group calendar or a shared-mailbox calendar connection.

Capabilities and limits

Reads Outlook busy periods and creates, updates, or cancels booked-call events through Microsoft Graph.

• A work or school account is required; personal Microsoft accounts are not supported by the availability API used here.
• No Calendars.ReadWrite.Shared or application-level tenant installation is requested.

Connecting, renewal, and removal

When enabled in this environment, connect from Settings → Integrations → Your integrations. Team-content integrations also appear under Workspace, but still use your own authorization. An expired or revoked grant needs Reconnect. Disconnect removes your SellAnyBiz connection; it does not transfer or delete copies already imported into a room or listing. Google/Microsoft provider consent may remain because sibling integrations share a client.
