office 365 autodiscover not working outlook

This behavior can also happen with the Outlook mobile app, as reported on the forums. And yet, when I was configuring Outlook 2016, I kept getting the following popup:Īt first, I thought that maybe it was just an additional popup, and tried to authenticate as normal, but with no success: The oddest part about it is that Autodiscover was configured correctly – even doing an Autodiscover test on would work correctly with no issues. Probably the last thing just looking at the code your using is that this could all be done in the Microsoft Graph API (PowerAutomate probably as well) which will let you reduce the number of permissions your app needs, give you more flexibility in how/where you run it and give whatever process your working on a extended life (in the Case EWS is switched off at any point in the future).I ran into an issue recently while performing a G Suite to Office 365 migration where my Outlook 2016 clients would begin to Autodiscover as normal, but rather than redirecting to Office 365 as I expected, they would actually present me with a Gmail IMAP login prompt. One other issue with your code is the its using Basic authentication which is going way in October so consider using oAuth instead. Using (StreamWriter sw = new StreamWriter(logFilePath, append: true)) Result = exchange.FindItems(WellKnownFolderName.Inbox, sf, new ItemView(100)) ĮmailMessage message = EmailMessage.Bind(exchange, item.Id) įileAttachment attachment = (FileAttachment)message.Attachments Īttachment.Load(extractFilePath + + attachment.Name)

SearchFilter sf = new SearchFilter.IsEqualTo(EmailMessageSchema.Subject, filterSubject) SearchFilter ff = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, emailFolder) įindFoldersResults fresult = rootFolder.FindFolders(ff, new FolderView(1)) String logFilePath = ConfigurationManager.AppSettings + ĮxchangeService exchange = new ExchangeService(ExchangeVersion.Exchange2007_SP1) Įxchange.Credentials = new WebCredentials(emailName, emailPassWord) Įxchange.AutodiscoverUrl(emailName, RedirectionUrlValidationCallback) įolder rootFolder = Folder.Bind(exchange, WellKnownFolderName.MsgFolderRoot) String emailFolder = ConfigurationManager.AppSettings String extractFilePath = ConfigurationManager.AppSettings String filterSubject = ConfigurationManager.AppSettings String emailPassWord = ConfigurationManager.AppSettings String emailName = ConfigurationManager.AppSettings However on the server it does not work and I get a 'The Autodiscover service couldn't be located.' error. I now need to deploy this onto a Windows server (2019) and run via a job scheduler. This app works perfectly on my development PC. Net c# console app to extract emails from an Office365 mailbox with specific credentials.
