You will usually see this behavior if the OWA web-services are not sending the correct data, or if the data is being corrupted over the wire.  Nav Coporate 8 does not have any "firewall" features, so that shouldn't be a problem. 
 
Does she have any software firewalls that may be preventing this particular WS not to work?  BlackIce with just the right ruleset is known to do this.  Basically, any software (or hardware) firewall that blocks outgoing communications may cause an issue in this case.  Of course, any obtrusive incoming firewall/anti-virus/anti-malware may do the same.

Subject: [MSUNAG] Cannot send or reply to e-mail with Outlook Web Access

We have over 2,000 users on our Exchange Server (2003) and offer Outlook Web
Access to our users. 

Recently, it was brought to my attention that one faculty member who is
semi-retired and lives near Charlevoix cannot send or reply to e-mails with
Outlook Web Access.  When she clicks on the Send button, the button dims,
but the page looks like it is frozen.  It will not eventually send if she
lets it sit there. 

After talking to her, I noticed that she was in need of many Windows Updates
on her computer and was still running Internet Explorer 6.  I had her
install the latest patches/updates and also upgrade to IE 7.  As always, she
can log into OWA, can open any e-mail, but cannot send a new or reply to an
existing message.

She has already deleted all Temporary Internet Files, reset IE back to
defaults, and still not working.

I had her download and install Firefox and she is still having the same problem.

The computer that she is having this problem with has Symantec Anti-virus
Corporate Edition (ver. 8.1.0.825) and my department does not use it, so I
am unsure of what options to try and disable to see if this is causing the
problem or not. 

Her laptop which is issued by our department and configured with our
antivirus software (Computer Associates E-trust) works just fine.  It is her
home desktop that is having this trouble.


Anyone have any ideas? 

Thanks in advance.
