My friend Google led me to this fix:

which also failed with:
Mailbox could not be created. Verify that OU ( Users ) exists and that password meets complexity requirements.
Yes & Yes.
My friend Google helped me out again, as the client has more than one OU with the name ‘Users’ in the title (Main Office Users, Test Users, Remote Office Users) with the following:

advising me to specify the OU as follows:
.\new-TestCasConnectivityUser.ps1 -ou domain.local/users
Woo-hoo. Success. Got there in the end. Thank you. Now what was I trying to do in the first place?
