I think there's nothing wrong with this, but PBI disagrees:
The expression refers to multiple columns. Multiple columns cannot be converted to a scalar value.
I want this to do more, but I have it stripped down to the bare minimum requirements for troubleshooting. I've tried all kinds of tricks, but nothing seems to be working.
Summarize = SUMMARIZE(
MailboxStatisticsHistorical,
MailboxStatisticsHistorical[Date],
"Distinct", DISTINCTCOUNT(MailboxStatisticsHistorical[Identity])
)

SUMMARIZE returns a calculated table. You can't assign it to a measure. (Measures expect scalar results.) Use the Calculated Table UI instead.
