Accept the invitation
In this step you accept the invitation to join your organization in On-Call Optimizer. If you don’t have an On-Call Optimizer account yet, one is created when you first sign in.
1. Click the link in the invitation
The invitation email contains a link, as shown below.

Click the link to open On-Call Optimizer.
2. Sign in
The Welcome page shows which organization you’ve been invited to join, and a single sign-in button for the provider your organization uses: Sign in with Google or Sign in with Microsoft. Click it and sign in with your work account.

Signing in accepts the invitation. Your account is created automatically the first time you sign in.
Email address mismatches
3. You’re in
There’s no separate step to accept: signing in from the Welcome page accepts the invitation for you. If the Welcome page shows an Accept invitation button instead of a sign-in button, click it.
Once you’ve joined, the members of your schedules can see the availability information imported from your calendars.
Next steps
After accepting the invitation, you’re taken to Home, where the Welcome to On-Call Optimizer pop-over offers to connect your calendar.
