i set the webpart to communicate with an exchange calendar
all is working fine until i leave as unique user the id that has the name of the mailbox, but when i check "use current logged-in windos credential" the authentication popup come on continuosly.
the problem seems that in this way exchange 2010 cannot know which is the mailbox we are looking for (in the first case it recognized it by the loghin name). inthe old exchange version you could use http://exchangeaddress/yourmailbox
but in 2010 it seems it do not accept this URL format but only http://exchangeaddress/
is there a solution?
many thanks to all in advance
