Our company is looking at converting from our existing Schedule+ and Microsoft Messaging to Microsoft Outlook. I am having problems finding what is needed to set us up properly. We are currently using the Microsoft workgroup Postoffice (Microsoft Mail) which is a directory on our network. When Schedule+ was initially setup on each person's PC the application automatically creates a sequential file (00000001.scd) in the postoffice in a directory called CAL. If I use Microsoft Outlook using Microsoft Mail as the services, the mail portion of Outlook is working fine, but the Calendar portion is not. I cannot view others calendars and I cannot synchronize my calendar. I don't believe there is a network copy of the calendar. I can't get an answer from any of my sources whether in order to do this I must use Microsoft Exchange Server. Can anyone help?
