Why is it possible to run this query:
GET /v1.0/me/messages?$filter=singleValueExtendedProperties/Any(ep: ep/id eq 'Binary 0x300B' and cast( ep/value,Edm.Binary) eq binary'yx==')
against messages and contacts, but not against events?:
Example:
GET /v1.0/me/events?$filter=singleValueExtendedProperties/Any(ep: ep/id eq 'Binary 0x300B' and cast( ep/value,Edm.Binary) eq binary'yx==')
which gives the answer: ErrorRestrictionTooComplex
Like this question: Microsoft Graph: Unable to filter by binary singleValueExtendedProperty it was once possible.
