Hi,

You are on to the right idea...just looking in all the wrong places.

Your email account is originally stored on your ISP's servers. Outlook is just what is used to forward the email to your computer
. The original mail is still stored on your account with your ISP. Normally the default settings would allow older mail of 30 or 60 or what ever amount of days stored to be dumped regularly. The problem with this is that the longer the storage time and then the more emails you get become compounded and you have reached the allotted amount of capacity that your ISP will allow.

What you need to do is do a maintenance on the email accounts from your ISP. You need to log on to your ISP home page and the email account that was originally set up when the account was created. Clean out all the stored emails from there

Now look at outlook and under tools options maintenance Tab check to clean up stored emails. A new bow will open and allow you to either compress to save space or empty all the stored emails. Another option would be to change the location of the folder to a different location...you can do that and the clean out what you want to save...delete the rest and then move the folder back and start over.

To prevent this from continuing make sure that the account there is set to default levels and it should keep the amount of storage space down to a minimum.
