Removing onmicrosoft.com from M365 usernames needs sifoidak.com verified as a custom
Entra domain, which needs a DNS TXT record at GoDaddy. Mike confirmed ACG has no
registrar access to that account, so UPNs stay on sifoidak.onmicrosoft.com and new
users follow the same convention. Recorded as decided rather than blocked so it is
not re-proposed.

Sif-oidak was documented as a hybrid AD/M365 environment. It is not: there is no
Entra Connect on either DC, no AD object carries msDS-ConsistencyGuid, and every
M365 user has onPremisesSyncEnabled=null. AD and M365 are disjoint, and email is a
third system entirely (sifoidak.com at GoDaddy; the O365_BUSINESS SKU carries the
EXCHANGE_S_FOUNDATION no-mailbox stub).
That mismatch caused a real failure: Dwayne Ortega had a cloud account only, so he
could not log in to a domain-joined workstation. Created his AD account and recorded
the two-account onboarding rule.
Also documented: printer error 740 (Point-and-Print driver install needs admin,
UAC prompt never surfaces), a GPO pushing the MX-6240N queue from the wrong server,
SIF-SERVER2 confirmed as a backup DC, and refreshed stale laptop agent UUIDs.
