O365: Enable Application Impersonation
KB ID 0001449 Problem While using a migration tool to do some ‘on-prem’ to Office 365 migrations I had to enable ‘Application Impersonation’ for my Office 365 user. The tool didn’t explain how to do that, so I had to work it out for myself 🙁 So to make things easier for everyone else, here’s how to do it.
