I am trying to display Outlook calendar in Sharepoint 2013 on premise. I have done following things in Calendar Overlay added Outlook Web Access URL and Exchange WebService URl. But still i am getting this error:
For solution i have added Work email in Manage User property and Setup outgoing email also and Synchronized user profile but no effect.
I have tried to do same in office 365 but in that i am getting following error.
The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Basic Realm=""'. (6334659d-901b-2000-2122-cb1effb031c8)
So any solution for that.??
