No problem. But then… throwing out the old feels good, it makes room, metaphorically if not actually, for the new, and — who knows — maybe it makes Mac OS X Mail faster, too.
It's even better when finding the stale and getting rid of it is so easy as it is with Mac OS X Mail's store of previously used addresses.
Clean Up Mac OS X Mail's Auto-Complete List
To clean up or empty the auto-complete list of previous recipients' addresses in Mac OS X Mail:
- Select Window | Previous Recipients from the menu.
- Click on the Last Used header so the addresses are sorted with the least recently used on top.
- Click the header until you see a triangle pointing downwards in it.
- Make sure no entry is highlighted.
- To deselect all, first highlight just one, then deselect that address by holding down the Command key while clicking it.
- Hold down the Shift key.
- Click on an address last used a year ago.
- Of course, you can choose a different interval and select all addresses not used in the past month, for example.
- Verify all entries not used in the last year are highlighted.
- Click Remove From List.
