BusyCal on the mac, starting with v2023.1.3, allows you to add Microsoft Teams meetings to all your Office 365 events.

Repeated Authentication Prompts

If you're seeing repeated authentication prompts, this may indicate that your Office 365 Account Admin has blocked access to Teams or related security scopes (required for Teams integration). The following security scopes are additional permissions required by BusyCal (in addition to the usual EWS Exchange Web Services permission) to be able to integrate with Microsoft Teams. These may need to be approved by the O365 admin separately:

• Calendars.ReadWrite
• User.Read
• User.ReadBasic.All
• Calendars.ReadWrite.Shared
• Tasks.ReadWrite
• Tasks.ReadWrite.Shared
• People.Read
• MailboxSettings.Read

If approval of these additional permission scopes is not possible, your only option is to disable Teams integration in order to continue syncing with your account Office 365 account normally. To do this, open BusyCal Settings > Accounts, select the Office 365 account and uncheck "Enable Microsoft Teams Integration".
