Dumb question time.
Excel is for spreadsheets, complex calculations and is great at charting and is good for data that is wide (goes from right to left).
Outlook is for tasks, email, appointments and scheduling.
Access is for relational data storage and mining and works best when data is vertical.
If you have something that works in Excel why on earth would you replicate it in a relational database?
I have seen something for Access that is like an Outlook calendar, but that's not what you seem to want - otherwise I'd post a copy for you.
The more we hear silence, the more we begin to think about our value in this universe.
