Outlook fliye Shared Calendar Permissions Not Working Outlook 365

Outlook fliye Shared Calendar Permissions Not Working Outlook 365. My colleagues have shared their calendars with me but when i add them via the add calendar button (search via address book, double click their name, click ok). When i hit the share calendar in my home calendar, absolutely nothing.

All was great until recently. You can give someone in your organization permission to manage your outlook calendar by granting them edit or delegate access.
