Everything was fine till last week when we upgraded to Exchange 2007 SP2 Rollup 1.  After this upgrade our code stopped working and start throwing following exception: Error Code: Microsoft.Exchange.WebServices.Data.ServiceError.ErrorNoDestinationCASDueToVersionMismatchError Message: The account accessing the resource must be on the same Mailbox Server version as the delegate account being accessed.  Following is the code sample code we are using and program crashes at RED line Dim service As New ExchangeService(ExchangeVersion.Exchange2007_SP1)service.Credentials = New WebCredentials(sUserName, sPassword, sDomain)service.Url = New System.Uri(sWebServiceUrl) Dim mailBox As New Mailbox(sMailBoxaddress)Dim oInboxFolderID As FolderId = New FolderId(WellKnownFolderName.Inbox, mailBox) Dim iItemView As New ItemView(100)     Dim hashMails As New Hashtable         Dim fl As SearchFilter.SearchFilterCollection = NothingIf alExcludeFrom.Count > 0 Thenfl = New SearchFilter.SearchFilterCollection(LogicalOperator.And)      For Each sToBeExcludeEmail As String In alExcludeFrom            fl.Add(New SearchFilter.IsNotEqualTo(EmailMessageSchema.From, sToBeExcludeEmail))      NextEnd IfDim findItemResult As FindItemsResults(Of Item) = service.FindItems(oSourceFolderID, fl, iItemView) I have tried bethout using ExchangeVersion.Exchange2007_SP1 parameter but then I receive error saying:"Exchange server doesn't support requested version."  Please help. RegardsManoj  解决方案 Please update all your CAS servers to SP2 RU1. EWS does not support cross-version requests, which is why you are getting this error. The CAS you are hitting is SP2 RU1 but the CAS that can retrieve the information for the targeted mailbox is not. 这篇关于带有Exchange 2007 SP2汇总1的EWS API 1.0存在问题的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
