Sending Shared Calendar Invitation using Exchanged Managed API in office365 giving internal server error

    Question

  • Hi ,

    I have used Exchanged Managed API to carry out some customization in Exchange online. I want to send a shared Calendar invitation to the exchange users in office365. But getting below error

    An internal server error occurred. The operation failed., Value cannot be null. Parameter name: frontEndLocator .

    I search for this parameter but didn't find any information related to this parameter. Is it some extended property that needs to be set or any other invitation  parameter. I have used the same code in Exchange 2010 and it was working.

    I have used the code from this for sending the shared calendar invitation:
