We discovered a problem with our Exchange 20007 server (all updates installed) when our Outlook 2011 for Mac clients could not connect. OWA works, as well as other Exchange clients (Outlook 2010, 2013, iPhone, android). Apparently, Outlook 2011 relies on EWS and thus that is where the problem lies.
We've tried putting in https://ourserver/EWS/Exchange.asmx
in the server setting on the client, but to no avail. When we browse to that address in a browser, we get 500 Internal Server Error. If you go to that address on the server itself though, you get an HTTP Error 500.19 - Internal Server Error, which says the requested page cannot be accessed because the related configuration data for the page is invalid.
Under the detailed error information, two lines of interest are the following:
Config Error: Configuration file is not well-formed XML
Config File: \\?\C:\Program Files\Microsoft\Exchange Server\ClientAccess\exchwe
That web.config file is blank. I already did a Remove-WebServicesVirtualD
irectory and New-WebServicesVirtualDire
ctory to try to repair it, but that seemed to have no effect.
I am in a real pickle, as many of our users are Mac (Outlook 2011) users. Any help is greatly appreciated.
