Outlook calendar not saving details

Using Outlook for Mac 16.86 and Mac OS Sonoma 14.5. I have an Office 365 subscription.

I receive calendar invitations through my iCloud email address in Outlook, but when I accept them (sometimes I cannot even reply), the details are not saved in my calendar. (e.g., for a Teams meeting - the Teams information and link do not save to the calendar appointment.

All I see is the title of the meeting and the time - opening the appointment, it is blank.
