One of my customers cannot acceess DWA Domino Web Access for mail on his machine since upgrading to ie7. This is obviously a pain, one solution I found when accessing my mail on my Nokia N80 is to add to the url: ?open&ui=webclient

For example, if his mail was:

http://adfos.com/mail/username.nsf

he can access his mail by going

http://adfos.com/mail/Anon.nsf?opendatabase&ui=webclient

or

http://adfos.com/mail/Anon.nsf?open&ui=webclient

Quite useful, of course I'll have to turn off the java applets again... :)
