We are using shared calendars on 365, when one of the delegated officials with full rights creates an appointment on behalf of the owner, it states that the owner had scheduled the meeting. A few minutes later, it reverts to the delegated official as the creator and will not permit any further edits to that appointment. We have tried numerous ways to eliminate this challenge and had logged a call with MS and still do not have a resolve in hand. Has anyone come across this situation (we had recently migrated from on prem to exchange online)
