Desktop
Your call history is located in the center of the calls panel and shows a list of past calls (including missed calls).
Go to Calls > History. From any call in the list, select More actions
> Call back
to begin a call automatically.
You can also chat with that contact, add them to speed dial, add them to your contacts, and block the number — all from the More actions menu.
Notes:
Your call history is available if you have an Enterprise Voice or Business Voice license as part of your Microsoft 365 subscription.
Entries in your call history cannot be deleted.
