Today I tried to create an item in calendars using Nintex on Office 365. I configured a service account and an user account to impersonate. But my workflow kept giving me:
The request cannot be processed due to internal error.
I found an article by Danny Ong. However Danny is using the email@example.com account. Where I’m using my service firstname.lastname@example.org and I’m impersonating email@example.com.
Once I changed my service account to firstname.lastname@example.org the problem went away.
My email@example.com has a calendar within our domain where firstname.lastname@example.org doesn’t have a calendar. This seems to be needed.
