Outlook 2025 Share Calendar Greyed Out Windows 10. If you don’t have the option to share your calendar (maybe it is grayed out), it can also be because your network admin or it support set a policy preventing calendar sharing among. After you add a shared calendar in outlook desktop, you are not able to select the checkbox next to the name.

We’ve made major updates to the way outlook for windows connects to and updates shared calendars. I’m using imap email provided by my web hosting service, but can’t share my outlook calendar, as share calendar is greyed out.
