ErrorChangeKeyRequiredForWriteOperations

This error is returned when the change key for an item is missing or stale. For SendItem, UpdateItem, and UpdateFolder operations, the caller must pass in a correct and current change key for the item. Note that this is the case with UpdateItem even when conflict resolution is set to always overwrite.

ErrorContentConversionFailed

GetItem returns this error when Exchange Web Services is unable to retrieve the MIME content for the item requested.

ErrorInsufficientResources

This error occurs when the mailbox server is overloaded. Try your request again later.

ErrorInternalServerTransientError

This error indicates that an internal server error occurred and that you should try your request again later.

ErrorInvalidAttachmentId

This error is returned by GetAttachment or DeleteAttachment when an attachment that corresponds to the specified ID is not found.

ErrorInvalidAttachmentSubfilterTextFilter

This error 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, Exchange Web Services cannot render the XML for that filter. 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 GetFolder on the folder, but do not request the SearchParameters property.

ErrorInvalidChangeKey

This error occurs when a consumer passes in a folder or item identifier with a change key that cannot be parsed. For example, this could be invalid base64 content or an empty string.

ErrorInvalidCompleteDate

ErrorInvalidExpressionTypeForSubFilter

This response code is not used.

ErrorInvalidExtendedPropertyValue

This error occurs when the value section of an extended property does not match the type of the property; for example, setting an extended property that has PropertyType="String" to an array of integers will result in this error. Any string representation that is not coercible into the type that is specified for the extended property will give this error.

ErrorInvalidFolderTypeForOperation

This error indicates that the specified folder type is invalid for the current operation. For example, you cannot create a Search folder in a public folder.

ErrorInvalidFreeBusyViewType

This error occurs when the GetUserAvailability Operation is called with a FreeBusyViewType of None.

ErrorInvalidOofParameter

This response code is not used.

ErrorInvalidPagingMaxRows

This error occurs when a consumer passes in a zero or a negative value for the maximum rows to be returned.

ErrorInvalidPercentCompleteValue

This error is returned when an attempt is made to set a task completion percentage to an invalid value. The value must be between 0 and 100 (inclusive).

ErrorInvalidPropertyAppend

This error occurs when the property that you are trying to append to does not support appending. The following are the only properties that support appending:

• Recipient collections (ToRecipients, CcRecipients, BccRecipients)
  
• Attendee collections (RequiredAttendees, OptionalAttendees, Resources)
  
• Body
  
• ReplyTo
  

In addition, this error occurs when a message body is appended if the format specified in the request does not match the format of the item in the store.

ErrorInvalidPropertyForExists

This error occurs if the consumer passes in one of the flag properties in an Exists filter. For example, this error occurs is the IsRead or IsFromMe flags are specified in the Exists element. The request should use the IsEqualTo element instead for these as they are flags and therefore part of a single property.

ErrorInvalidPropertyRequest

This error occurs if a property that is specified in the request is not available for the item type. For example, this error is returned if a property that is only available on calendar items is requested in a GetItem call for a message or is updated in an UpdateItem call for a message.

This occurs in the following operations:

• GetItem Operation
  
• GetFolder Operation
  
• UpdateItem Operation
  
• UpdateFolder Operation

This error indicates that the search folder has a recipient table filter that Exchange Web Services cannot represent. To get around this error, retrieve the folder without requesting the search parameters.

ErrorInvalidRecipientSubfilterTextFilter

This error indicates that the search folder has a recipient table filter that Exchange Web Services cannot represent. To get around this error, retrieve the folder without requesting the search parameters.

ErrorInvalidRequest

This error occurs when the SOAP request has a SOAP action header, but nothing in the SOAP body. Note that the SOAP Action header is not required as Exchange Web Services can determine the method to call from the local name of the root element in the SOAP body.

ErrorInvalidRoutingType

This error occurs if the routing type that is passed for an EmailAddressType is invalid. Typically, the routing type is set to Simple Mail Transfer Protocol (SMTP).

ErrorInvalidUserSid

This error occurs when an invalid SID is passed in a request.

ErrorInvalidValueForProperty

This error indicates that the comparison value in the restriction is invalid for the property you are comparing against. For example, the comparison value of DateTimeCreated > true would return this response code. This response code is also returned if you specify an enumeration property in the comparison, but the value that you are comparing against is not a valid value for that enumeration.

ErrorIrresolvableConflict

This error indicates that conflict resolution was unable to resolve changes for the properties. The items in the store may have been changed and have to be updated. Retrieve the updated change key and try again.

ErrorItemNotFound

• CreateItem and UpdateItem operations when the item being created or updated is a Message.
  
• CancelCalendarItem, AcceptItem, DeclineItem, or TentativelyAcceptItem response objects.
  

ErrorMimeContentConversionFailed

This error occurs when the MIME content is not a valid iCal for a CreateItem Operation. For a GetItem Operation, this response indicates that the MIME content could not be generated.

ErrorMimeContentInvalidBase64String

This error occurs when the MIME content in the request is not a valid base 64 string.

ErrorNoDestinationCASDueToSSLRequirements

This error 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 SSL connection,s and therefore the request could not be proxied.

ErrorNoFolderClassOverride

This error 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 Operation 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.

ErrorNonExistentMailbox

This error occurs in the following scenarios:

• The e-mail address is empty in CreateManagedFolder.
