I am using Outlook 98, windows 98 and Explorer 5.01.<br>When sending email attachments to numerous people around the same time, there are 4 of them that do not receive the attachment approximately 98% of the time.<br>I have sent them 5 consecative emails all the same, still the problem existed.<br>The attachments are on average 400KB per email, so the files are not large.<br>I have sent them in Jpeg, Bitmap, Ziped, Word format but they do not receive.<br>I have spoken to my ISP but have not received an understandable answer.<br>I would be pleased if somebody could offer an explanation.
