Hello A company uses an Excel spreadsheet with rows titled: Bill, Joan, John etc., and columns titled: July 7 2011, July 8th 2011, etc.. They use this as a central company calendar - they can see what anyone was/is/will be doing on any day - all on one page - kind of like a Gant thing I guess. How can they do this in Exchange 2003/Outlook 2007/2010. Side by side calendars don't really do the same job.

There is nothing really close to that in Exchange. The closest you get to a direct replacement for a manual solution is Public Folders. However if you want something a little more automated then you will have to look at something third party - "Look" from Symprex is one that that immediately springs to mind.

Another thing you can try and if it works with you is to setup a shared-mailbox, share the calendar or give mailbox permissions to the users and they can add as an additional mailbox and all use the same calendar and put their enteries in there.Sukh

Sharepoint is another option. Since you are using Exchange 2003, the resource mailbox option is not as great, but still possible and if you are using the autoaccept agent will provide a better experience for the end user.

Many thanks, Sembee, Sukh828 and AndyD for your suggestions. As far as I can see each has advantages and disadvantages: Symprex would work but is is a bit primitive, old school and costly A shared mailbox goes against the principle of never creating generic mailboxes They have already tried SharePoint calendars which are not great. I will investigate the Shared Mailbox/Calendar thing further
