Get Outlook to Automatically Delete Old Trash
One of the nice features of Max OS X’s Mail application and, I think, Mozilla Thunderbird, is that they will permanently delete messages from trash older than a month (i.e., they keep a month’s worth of deleted items). To get the same functionality in Microsoft Outlook connected to an Exchange Server, I had to do the following:
- Right-click “Deleted Items” and choose “Properties”.
- Click on the Auto-Archive tab.
- Select the “Archive this folder using these settings:” option/radio button.
- Under that option, choose the “Permanently delete old items” option/radio button.
- Click the “Apply” button.
I think Outlook won’t do this until its Auto-Archive process runs. Start it manually from the Tools > Mailbox Cleanup dialog box.
