I just found this out myself the other day, you can remove attachments from emails in Outlook. Handy for reducing your Exchange mailbox size.
Just open the email (can’t be done from preview), right click the attachment and select Remove. Close and save the email when prompted.
Do you get the following error message when clicking on a hyper link in Outlook 2003?
This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator.
This is usually very easily fixed. Go to Control Panel> Internet Options> Programs> Reset Web Settings.
That should fix it!
If you get when composing or replying to an email in Outlook 2003 you get the following error message: “Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly”. This is probably caused by your Outlook email signature.
This will usually occur if you used the advanced edit to edit your signature. It is caused by the smart tags Word adds into the HTML. The easiest way to fix this is to recreate your Outlook signature from scratch without using the advanced edit. This worked for me.
