I back up my Outlook folders as Excel spreadsheets. The easiest method I've found is:
1. Open the Outlook folder as a table in Access.
2. Copy the Access table and paste as plain text into the spreadsheet.
3. Delete the table from the Access DB.
Outlook's native export-to-Excel function doesn't export all of the information I need – this method does, and it's faster, too.
The only drawback to this method is that it creates two new Access MDB files each time (one in C:Program FilesCommon FilesSystemMSMAPI1033, and one in My Documents). No, it doesn't take long to delete them... But still, isn't there a way to avoid creating the two new MDB files, given that I don't perform any Save function in Access?
