We have iGoldMine CRM running on the server, which is access by citrix client by 20 users.

iGoldMine CRM has calendar that can sync to office installed on the server. Our challenge is for that outlook to sync calendar across all the users. 

How do we go about doing this.

Our discovery

1) Install 20 outlook profiles on the CRM server and let it sync to CRM calendar. Eventually it will sync with local client of users. However drawback to this method is that 20 outlook profile is downloading all the emails on that server creating space, security and I/O issue.

yesterday I found out that exchange allows you to create shared profile which then can be link to other accounts. if that is the case then we can have shared outlook profile running on CRM server and let calendar syn to shared profile. 

my question

1) Is there a better way.

2) Would Shared profile method work.

3) When I try login in with shared profile on microsoft site, it gives me below error.
