Indicates that the attachment was not found within the attachments collection for the item. For example, you may receive this response code if you have an attachment ID and then the attachment is deleted and you try to call the GetAttachment(GetAttachmentType) method on the attachment ID.

Occurs when you try to bind to an existing search folder by using a complex attachment table restriction. Exchange Web Services only supports simple contains filters against the attachment table. If you try to bind to an existing search folder that has a more complex attachment table restriction (a subfilter), Exchange Web Services cannot render the XML for that filter and returns this response code.

In this case, the attachment subfilter contains a text filter, but it is not looking at the attachment display name. Note that you can still call the GetFolder(GetFolderType) method on the folder, but do not request the SearchParameters property.

Indicates that the authorization procedure for the requester failed.

Indicates that an invalid change key was passed in. Note that many methods do not require a change key to be passed. However, if you do provide a change key, it must be valid, although not necessarily up-to-date.

This response code is not used.

Occurs when the combination of extended property values that was specified are invalid or result in an invalid extended property Uniform Resource Identifier (URI).

Indicates that the value that was offered for the extended property is inconsistent with the type that was specified in the associated extended field URI.

Indicates that the structure of the ID is internally inconsistent. The moniker is contained within the ID and indicates which mailbox the ID belongs to. This response code is returned if the length of the moniker is checked and the byte count is longer than expected.

Occurs when the AttachmentId property does not refer to an item attachment.

Indicates that a contact in your mailbox is corrupt.

MeetingMessages objects, for example, are created when you send a calendar item to attendees; they are not explicitly created.

Indicates that you tried to create an item attachment by using an unsupported item type. Supported item types for item attachments include ItemType, MessageType, CalendarItemType, TaskType, and ContactItemType objects.

Indicates that the property that you are trying to manipulate does not support the operation that is being performed on it.

Occurs if the property that is specified in the request is not available for the item type. For example, this response code is returned if a property that is only available on calendar items is requested in a GetItem(GetItemType) method call for a message or is updated in an UpdateItem(UpdateItemType) method call for a message.

Indicates that the property you are trying to set is read-only.

Occurs during an UpdateItem(UpdateItemType) method call when a client tries to update certain properties of a message that has already been sent. For example, the following properties cannot be updated on a sent message: IsReadReceiptRequested and IsDeliveryReceiptRequested

This response code is not used.

Occurs if you called GetEvents(GetEventsType) or Unsubscribe(UnsubscribeType) on a push subscription ID. To unsubscribe from a push subscription, you must respond to a push request with an unsubscribe response, or disconnect your Web service and wait for the push notifications to time out.

To fix this error, you must resynchronize without the sync state. Make sure that if you are persisting sync state blobs, you are not accidentally truncating the BLOB.

Indicates that the specified time interval is invalid. The start time must be greater than or equal to the end time.

Indicates that a user ID has not been fully specified in a permissions set.

Indicates that you have specified more than one ExchangeImpersonation property value within a request.

Occurs if there is no Calendar folder for the mailbox.

Indicates that the request referred to a mailbox in another Active Directory site, but no Client Access servers in the destination site were configured for Windows Authentication and therefore the request could not be proxied.

Occurs if you set the FolderClass property when you are creating an item other than a generic folder. For typed folders such as CalendarFolderType and TasksFolderType, the folder class is implied. Setting the folder class to a different folder type by using the UpdateFolder(UpdateFolderType) method results in the ErrorObjectTypeChanged response. Instead, use a generic folder type but set the folder class to the value that you require. Exchange Web Services will create the correct strongly typed folder.

Indicates that the caller does not have free/busy viewing rights on the Calendar folder in question.

Indicates that the operation could not be completed because of insufficient memory.
