The following has started to appear every few days “To free up disk space, Outlook Express can compact messages, This may take up to a few minutes”. I click on OK but what does it mean as I regularly delete all my old e-mails the next day.
In Outlook Express you can check the settings for compacting messages if you go to >Tools > Options > Maintenance
...if it helps mine has a tick in 'Compact messages in the background'. Also in 'Compact messages when there is ** percent wasted space' I have got it set at 20 (per cent) I have no idea if this is an ideal setting or not.... but it works for me :)
