Update event does not work with EWS Access Denied - soap

Question

I am creating Meeting from application using EWS. With soap request
{
"body":{
"m:CreateItem":{
"attributes":[
{
"SendMeetingInvitations":"SendToAllAndSaveCopy"
}
],
"m:Items":[
{
"t:CalendarItem":{
"t:Subject":"Booked from application",
"t:Body":{
"attributes":[
{
"BodyType":"Text"
}
],
"value":"Meeting body"
},
"t:Start":"2016-03-02T13:11:59+00:00",
"t:End":"2016-03-02T13:45:00+00:00",
"t:Location":"room1",
"t:RequiredAttendees":[
{
"t:Attendee":{
"t:Mailbox":{
"t:EmailAddress":"room1#testdomain.onmicrosoft.com"
}
}
}
]
}
}
]
}
},
"headers":{
"Authorization":"Basic somestringsdafsdfsdfsdfsdfsf"
},
"additionalNamespaces":[
"xmlns:m=\"http://schemas.microsoft.com/exchange/services/2006/messages\"",
"xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\""
],
"soapHeader":{
"t:ExchangeImpersonation":{
"t:ConnectingSID":{
"t:PrincipalName":"test007#testdomain.onmicrosoft.com"
}
}
},
"method":"POST",
"url":"https://outlook.office365.com/EWS/Exchange.asmx"
}
I am also trying to edit the meetings duration via application and it works fine also. With SOAP request:
{
"body":{
"m:UpdateItem":{
"attributes":[
{
"SendMeetingInvitationsOrCancellations":"SendToAllAndSaveCopy"
},
{
"MessageDisposition":"SaveOnly"
},
{
"ConflictResolution":"AlwaysOverwrite"
}
],
"m:ItemChanges":{
"t:ItemChange":{
"t:ItemId":{
"attributes":[
{
"Id":"AAApAHJvb20xQGNlcnR1c2ludGVybmF0aW9uYWwub25taWNyb3NvZnQuY29tAEYAAAAAAMWslF/s3JlHvuBz+Grw4nkHAMq37IYLqfhKh5oHo2fodacAAAAAAQ0AAMq37IYLqfhKh5oHo2fodacAAFweeHQAAA=="
},
{
"ChangeKey":"DwAAABYAAADKt+yGC6n4SoeaB6Nn6HWnAABcIvBS"
}
]
},
"t:Updates":{
"t:SetItemField":{
"t:FieldURI":{
"attributes":[
{
"FieldURI":"calendar:End"
}
]
},
"t:CalendarItem":{
"t:End":"2016-03-02T15:00:00+00:00"
}
}
}
}
}
}
},
"headers":{
"Authorization":"Basic somestringssdasasfasfasfasfaf"
},
"additionalNamespaces":[
"xmlns:m=\"http://schemas.microsoft.com/exchange/services/2006/messages\"",
"xmlns:t=\"http://schemas.microsoft.com/exchange/services/2006/types\""
],
"soapHeader":{
"t:ExchangeImpersonation":{
"t:ConnectingSID":{
"t:PrincipalName":"test007#testdomain.onmicrosoft.com"
}
}
},
"method":"POST",
"url":"https://outlook.office365.com/EWS/Exchange.asmx"
}
Where problems starts is, when I create meeting from outlook.office.com using Exchange web interface. I get error with message:
Access is denied. Check credentials and try again., Cannot get ID from
name.
The SOAP request is the same except change keys. I have read on some similar problems that it might be due to the rights on calendar. I am not quite clear with that.
Could you please advise on this problem.
EDIT:
{
"t:ExchangeImpersonation":{
"t:ConnectingSID":{
"t:PrimarySmtpAddress":"test007#testdomain.onmicrosoft.com"
}
}
}

Answer 1

It maybe your impersonation header is test007 the Mailbox your trying to access or just the service account your using ?
I'd suggest you use the PrimarySMTPAddress to ensure you are specifying the Mailbox to access rather then a user eg
"t:ExchangeImpersonation":{
"t:ConnectingSID":{
"t:PrimarySmtpAddress":"test007#testdomain.onmicrosoft.com"
}
Also when you say
Where problems starts is, when I create meeting from outlook.office.com using Exchange web interface. I get error with message
Do you mean you get the error in the Outlook Web App or in your code ?
