Hi,
I am having a problem accessing a mailbox on Office 365 through an Azure worker role application using EWS Managed API 2.2. This is the error message that I get:
The request failed. The remote server returned an error: (401) Unauthorized.
It works when using my mailbox, which is also on Office 365, but not when I try to connect to another that is to be used for this application. Both mailboxes are set up as part of the same corporate account in Office 365, but the domain for mine is [company].com, while the one that doesn't work is [company].net. EWS has been activated for both addresses. I can log in in to Outlook Web Access with the other account with no problems, so the login credentials are working. The strange thing is, it used to work about 2 months ago when I originally built the application and was testing. I hadn't tried to use it since then until yesterday, when I was testing it before deploying to production.
Are there any other settings that I can check that would prevent EWS from working for the other mailbox?
Thanks,
Chris
