Can you advise me? I have been using Outlook Express for years but I now have too many e-mails and the size of my store folder is about 6 GB which is causing the programme to run erratically and do strange things. As a result I am loosing valuable e-mails and information. Is there a better programme for e-mail and is Thunderbird good? I don't like Outlook.

   I use Outlook Express.  I cannot advise you about any other email program.  I would think that they would have similar problems.
   I only have 3 gb and that is over 10 years of business emails.  That is a lot of emails.
   If you don't have a lot of emails, you should to compact the messages and remove attachments.
   If you have a large amount of messages in one folder, dividing them up into smaller folders should also help.
