I know that this is an old thread, but I seem to have been travelling a
well worn path to the conclusion that Webmail+OWA doesn't work with an
Exchange 2007 server. In particular, Webmail+OWA is throwing exceptions
becuase HTML "<BASE tags" are not being found:

Error message: kOWABaseAlt is not defined

I got similar errors when trying to use the "owa-0-7-0a36.xpi" package I
downloaded from the newsgroup, so I checked out the sources from the CVS
repository, under Linux, to have a look and see why this is happening:
cd /usr/local/src
cvs -d :pserver:guest:[email protected]:/cvs login
cvs -z3 -d :pserver:[email protected]:/cvs co webmail
There is a "build.xml" file, so I used "ant" to rebuild the package:
cd webmail/src/owa
ant
So far so good - I can now rebuild the *.xpi package. I looked at the
source code where the errors are reported in:
owa/content/owa/OWA-ScreenRipper-POP.js
case 1: //get base URL
try
{
mainObject.m_szBaseURL = szResponse.match(kBaseURL)[1];
}
catch(e)
{
mainObject.m_szBaseURL = szResponse.match(kOWABaseAlt)[1];
}
mainObject.m_Log.Write("nsOWA - loginOnloadHandler - m_szBaseURL :" +mainObject.m_szBaseURL);
In my case "kBaseURLAlt" was not defined so I edited:
owa/content/owa/OWA-Constants.js
...
const kBaseURL = /<BASE href="(.*?)">/i;
const kBaseURLAlt = /<BASE target="(.*?)">/i;
...
There are two formats of "<BASE" tag so I assume that the first
exception is caught in case it is in the Alternative "<BASE target" tag.
However, the constant had not been defined. In the case where the first
"<BASE" tag was found an exception would not be thrown, and this must be
the case for Exchange 2003 or the code would not work at all.
So I rebuilt the *.xpi package and installed it, but I quickly realised
that no "<BASE tags" are actually generated by the Exchange 2007 server.
The more I look into the problem, the more I realise that the regular
expressions defined in "OWA-Constants.js" are not appropriate for the
Exchange 2007 OWA server. I've changed some of the regular expressions
and managed to get TB+Webmail+OWA to login on an Exchange 2007 server,
capture the URI of the OWA Inbox and the page number it is on, but I've
not managed to read the email into TB.
Before I go any further with this project I'd like to know if anyone
else is working on modifying the OWA Webmail addon source code for an
Exchange 2007 OWA server?
Thanks,
Tony.
