I'm not able to get to the 'you created a service' page. If I go to: https://outlook.office365.com/EWS/Exchange.asmx I'm prompted for a username + password. These are not my actual username + password, as those don't work. I believe if I was able to set up an application-specific password.. I'd be able to use that as the password. Unfortunately, those are disallowed per my administrator. When I abandon the attempted sign-in, I get the butter-y yellow page that I'd expect for an EWS site. -justin On Mon, Aug 23, 2021, at 2:11 PM, Thomas Fitzsimmons wrote: > Hi Justin, > > "Justin Abrahms" writes: > > > I'm trying to setup excorporate for my new job.
