Hi all,

Please help me out there, I'm a student just graduated from college and working for a company in LA.

Our company has many shipping orders that I put into the a excel file, it's a huge database.

I understand how to import this data sheet to Outlook 2010.

My goal now is when someone else MODIFIED the start date of one appointment from my Excel database OR input more data at the bottom in the future, when I upload it to Outlook calendar again, the calendar would replace the old appointment and have the MODIFIED one in there.

What it looks now is if I changed some of the dates, it will create new ones instead of replacing the old one.

Please help me with this issue.

Thank you and best regards!
