Is there a way to share all calendars on portal or Site level in acentral location(like how we can share in outlook).
You can add any SharePoint event list to Outlook and it will behave likeany other Outlook calendar. Look for the "Connect to Outlook" option inthe Actions menu.
In our oraganization lot of employees do not have e-mail and that is the mainneed to have some kind of solution on SharePoint(our Intranet).Please point me to right resources or 3rd party custom solutions to accomplishthis task.
CorasWorks has a "Roll-Up" calendar. It's about a $15 - $20K solution.
I believe what Jordon is referring to is CorasWorks' WorkPlace Suite but you can also use their AppEngine which is about $4k for a server and $8k for a farm. With this you can download a lot of free apps that are a great help when developing on SharePoint like the Event Calendar which allows you to share calendars community.corasworks.net/AppsHome.aspx%3Fd%3DASC%26T%3D28%26V%3D57%26s%3DTitle
