Outlook 2025 Shared Calendar Permissions Not Working Windows 10. Sharing calendar permissions not updating. Under options, calendar, calendar options, when i click.

You may try to remove all the permission and wait for sometime then only using the outlook on the web to share the calendar with user b to assign the permission to check the issue. On the rare occasion when we have to edit a users permission on the calendar, it’s hit or miss whether they will be listed on the currently sharing with: list.
