In our office, we have Office 2007. When trying to connect to Office Online for help, templates, etc, it can not connect. To test the firewall, I tried it on our guest wireless, which is a completely separate network using different firewall rules. I was able to connect.
This tells me it is a firewall issue. The strange thing is, when connecting back into the internal network, anything that had a connected session with Office Online on the wireless can now connect but anything I had not connected to on the other network still can not.
for example: I was on the wireless and connected to help and templates in Word. I jumped back onto the internal connection and both help and word templates are still available. I try Excel templates (which I did not access through the wireless) and it can not connect to Office Online.
I am thinking something was cached while on the wireless, so in an attempt to pinpoint the problem, clear IE cache and flush DNS. I try again and and can still connect to what I could before.
I have also checked the RSoP to see if anything in there could be effecting it but I do not see anything.
Thank you for your help!
