Not able to update a meeting request using updateItem operation

Hi ,

I am facing issue in updating a meeting invite using updateItem operation. I am getting following error response:
MessageText: 'The meeting request has already been sent and might not be updated.'
ResponseCode: 'ErrorSentMeetingRequestUpdate'

I am using latest version of node-ews. Has anyone faced this issue.

Please find below the payload of my request:

Hi, did you solve this issue?

I'm trying to update an e-mail and get the following response:

{"ResponseMessages":{"UpdateItemResponseMessage":{"attributes":{"ResponseClass":"Error"},"MessageText":"An internal server error occurred. The operation failed., Object reference not set to an instance of an object.","ResponseCode":"ErrorInternalServerError","DescriptiveLinkKey":0,"Items":null}}}

{ "attributes":{ "MessageDisposition":"SaveOnly", "ConflictResolution":"AlwaysOverwrite" }, "ItemChanges":{ "ItemChange":{ "ItemId":{ "attributes":{ "Id":"suppressed", "ChangeKey":"suppressed" } }, "Updates":{ "SetItemField":{ "FieldURI":{ "attributes":{ "FieldURI":"item:Sensitivity" }, "Message":{ "Sensitivity":"Confidencial" } } } } } } }

Anyone knows how to do that? I'm trying to mark a specific email as read, but I get the same error
