Cannot import ICS into Exchange calendar

[Timur Tabi]

I am unable to import ICS invitations into my Exchange calendar, even if they are sent by other users in my organization. I get an error dialog box that says:

Cannot receive calendar objects: Cannot find user "<email address hidden>" between attendees

I can import the ICS into my local calendar, but then when I try to move it to my Exchange calendar, I get a similar error message:

Cannot create calendar object: Cannot create meetings organized by other users in an Exchange Web Services calendar.

If I open the ICS file on my Windows PC, I can import it into Microsoft Outlook without any problems.

I'm hesitant to upload the original ICS as it's an internal meeting invitation, but here is the header with some names redacted:

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software at https://gitlab.gnome.org/GNOME/evolution/-/issues

If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.
