Lately, I have stumbled upon a rare issue using Mac Outlook calendar invitations.
External invitations disappear after accepting them in Mac Outlook v16.49.
Steps to reproduce:
- Appointment are scheduled via iOS Calendar and send from our Exchange Server within the same domain. I have added 1 internal and 1 extern participant. No fancy html formatting are being used.
- The invitation shows up just fine on the recipient Mac Outlook v16.49
- After accepting the invitation the calendar item completely disappears in Outlook calendar.
- No issue accepting invitation when using iOS calendar or macOS Calendar
- No issues accepting invitation on Windows Outlook
This pretty much looks like a bug in Mac Outlook v16.49. I am not able to reproduce this issue with an old Mac Outlook 16.16.27 version.
Any workaround? Any replies are highly appreciated.
