A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi
The copy of Microsoft Access you found can open your mdb file and show you the table information the mdb file contains. The mdb file is an attachment to the email message. It will not contain any information about the email message such as sender, to, email dates, etc.
Microsoft Access can save the table information as Excel workbooks, and then you can open them in Excel on Mac.
A detailed explanation of ODBC is here: https://en.wikipedia.org/wiki/Open_Database_Connectivity
A short explanation of ODBC is that you purchase and install an inexpensive (about $40 US) application called a "driver" that extends Excel's capabilities. The driver looks into the mdb file and finds the tables, which you can then import into Excel. That said, the same table information you see in Microsoft Access is what you will get with an ODBC driver. If Microsoft Access showed little or no data in the mdb file, you'll get the same result with an ODBC driver.
