If the option to create an appointment is greyed out, it may be due to insufficient permissions or the way the shared mailbox is being accessed. In environments like Exchange Server 2007 or 2010, users may only have access to view the calendar in a read-only mode, which prevents them from creating appointments directly in the shared mailbox's calendar. Instead, any new appointment may be created in the user's personal calendar with the shared mailbox added as an attendee.
To resolve this issue, you can check the following:
- Ensure that you have the necessary permissions to create appointments in the shared mailbox. You may need to be granted "Author" rights to the calendar.
- If you are using Outlook, you can assign the required permissions through the calendar properties.
- If you are using Outlook Web App, you may receive an error message indicating that you do not have the permissions to perform the action, which confirms the need for permission adjustments.
If you need to assign permissions, you can use the Set-MailboxFolderPermission cmdlet or adjust permissions through Outlook directly.
