Exchange OWA Rated 4 out of 5 stars
It would be very usefull if this plug-in could work with OWA. Our domain, for example is something.local, which is not dicoverable from outside the campus, tha means that connection string, you provide is uselees for us :(This review is for a previous version of the add-on (0.10).
