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 firstname.lastname@example.org account. Where I’m using my service email@example.com and I’m impersonating firstname.lastname@example.org.
Once I changed my service account to email@example.com the problem went away.
My firstname.lastname@example.org has a calendar within our domain where email@example.com doesn’t have a calendar. This seems to be needed.
