Firefox issue with Google Calendar Connector Web Service

[Scott]

We have found most installed versions of Firefox 3.0 and 3.5 are no
longer working with the Google Calendar Connector Web Service to pull
up calendar availability of our Exchange users. This feature was
working over the summer and still works with Internet Explorer 6/7,
Opera, Safari, and Chrome.

Checking the IIS logs, I found no connection to the Exchange Server
with Google Calendar Connector Web Service with the Firefox installs
that aren’t working. Also using Live HTTP Headers confirmed this for
Firefox installs that aren’t working with Google Calendar Connector
Web Service. We have tried clean installs of Firefox and disabling
all extensions and plugins, but that doesn’t help. The only two
Firefox installs that are working were running older versions, 3.0.12
and 3.5.0, and they continued to work even after upgrading to 3.0.14
&3.5.3 respectively.

Is anyone else experiencing this problem? Any suggestions on getting
this problem fixed so users can use Firefox?


Thanks,
Scott

Few suggestions:
1. Please check if javascript is enabled in firefox
2. If the free/busy service URI uses SSL (URI starts with a https://),
please check if the IIS server hosting calendar connector web service
has valid certificates. Even if the certificates are invalid, firefox
allows adding exceptions - point the browser to the free/busy uri
(something like
'https://<<exchange.server.uri>>/GCalExchangeLookup/ExchangeQuerier.apx")
and it will display a security failure page and also shows a link to
add an exception, at which time, one should add a permanent exception.

I cannot think of any other reason. Kindly let me know if the above
info could help.

Thanks!

Thanks Suman, you were correct about the SSL certificate. We are using one issued by a certificate authority on our Domain Controller, which explains why Internet Explorer on computers joined to the domain have no issues, but I don't know why Firefox stopping accepting it 2 or 3 weeks ago. We can manually add the SSL certificate into Firefox as a workaround. We will likely purchase a real SSL certificate in the near future as a longer term resolution to this issue.

Thanks,
Scott

Great troubleshooting work!

We buy a *.domain.com (wildcard) certificate from Equifax, and it
covers practically everything (except *.subdomain.domain.com hosts!).
Our load balancer hosts this cert as an SSL proxy, and the web service
servers can run without SSL.
