Windows Mail Slow

Information

This will show you how to fix four different causes for Windows Mail being slow.

NOTE

Check for each of these causes and follow the steps below for how to fix the issue for each of these. Known Cause Description Antivirus Program You have the email scanning options turned on in your antivirus program or your antivirus program is not compatible with Vista or Windows Mail. Restricted Sites List Some programs (ex:anti-Spyware) may add a large number of entries to the Internet Explorer restricted sites list. This can cause a severe performance problem in Windows Mail after installing the KB931768 Windows update before SP1 is installed. The slowness comes from Windows Mail having some kind of conflict with the update and the spy program making it read through the long list of restricted sites first. To Many Contacts For each 100 contact files in your Contact folder (name and email address totaling 2KB) there is a 0.25 second delay imposed by Vista for when you Create, Reply, Forward, or AutoFill a message. (EX: A 2 to 3 second delay for every 1000 contacts) The timing delay will vary due to processor speed and size of contact file. To Many Messages If you store or have a ton of messages in a mailbox folder (EX: Inbox), it can cause a delay while opening it. Large Attachment If you try to attach or receive a large file size attachment, then this can cause a slow receive or send depending on your internet speed.

Tip

A Workaround: Open Windows Calendar from within Windows Mail. (Tools -> Windows Calendar) Close Windows Calendar after a minute.
