Hello all :)
Have just noticed that OWA is not working.
Exchannge 2003 running on Win2003 with all latest updates and service packs.
In OWA, create an e-mail and click on To: to select a user from the contact list. Highlighting the name and clicking on To: to add it to the To: field does not work and IE displays an error message saying only 'Unknown'.
If you manually type in an e-mail address and click Send it will also display 'Unknown'. However, if you reply and send then it works OK.
Not sure why this is happening? Has been fine for months. Nothing in the Event Log either.
Can anyone help?
