On computers with a hard disk bigger than 64gb (which is most of them nowadays), Outlook will only keep emails from the last year on your computer. What’s going on?īy default, Outlook only keeps a certain amount of mail on your local client to make sure your email doesn’t take up too much space. That’s a lot of mail not visible in the local data.
This might not be the same as the size in the Local Data tab because Outlook doesn’t necessarily download all messages to your computer.įor example, on my Local Data tab the Total Size of the Archive folder is 116805 kb, but on the Server Data tab, the Total Size is 363399 kb-a difference of 246594 kb (265 MB). Once the tab is loaded, you’ll see the folder sizes on the Exchange server. This is because Outlook is contacting the Exchange server, asking for the data on your files (which is calculated on the fly), and then downloading and displaying the results.Įvery subsequent time you open this tab, the data retrieval will be much quicker, since Exchange only has to perform a difference analysis and most folders don’t change size that much.
The first time you open this tab, it might take a little while for the data to populate. If you want to see the size of the folders on the mail server, click the “Server Data” tab.
