I am trying to delete an Office 365 user's calendar appointments in bulk using Powershell. This account was turned into a shared mailbox earlier this year.

I have tried the following command: Remove-CalendarEvents -Identity <MailboxIdParameter> -CancelOrganizedMeetings
And it produces the error attached in the text file.

I have also tried specifying the date and time range of cancellation/removal with no positive effect.

Could it be as obvious as turning it back into a normal mailbox?
