Reporting a message with the Outlook plugin . . .

When I try to report a message with the Outlook plug-in, I get a 'Report Message is working on your Report Message request" until what appears to be a time out, then I get "We're sorry, we couldn't access Report Message. Make sure you have a network connection. If the problem continues, please try later." Do I need to open any firewall ports for this feature to work? We have a hybrid Exchange environment (Office 365 and on premise). The accounts I'm try to use are on premise, and the plugin was installed in the local Exchange environment.
