These settings come in very useful and have proven to work for me when a client had been using BPOS for example and moved either back to their own Microsoft Exchange server during a subsequent migration or have switched to another hosting service for email that also uses exchange. <br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-18662177.post-40043702375374647812015-03-24T10:52:22.962-07:002015-03-24T10:52:22.962-07:00Thanks, this saved me a lot of time.

You are right, the Anonymous Authentication is not present and until it is there is no way Outlook will completely setup. even manual configuration would not fix and complete the setup for the users. We had updated the operating system with all updates available and also applied a service pack to the installed Microsoft Office . None of these helped for what ever reason. We had found in some forums that updating the desktop operating system by running windows updates and also updating Outlook with the latest service packs and updates fixed it for some people with the same software issue. Unfortunately this did not work for us to get the software to completely configure and have a working user profile. The Microsoft hotfix enable or added the anonymous login and then the profile completely configured. it no longer prompt for the password. ben8499 - Desktop Tech Supporthttp://desktopremotesupport.blogspot.com/noreply@blogger.comtag:blogger.com,1999:blog-18662177.post-53394667501619176512015-03-24T10:07:05.492-07:002015-03-24T10:07:05.492-07:00Thank you very much for this post.

I had a situation where a client had migrated to Office 365. All Outlook clients were connecting to the Office 365 email server. Outlook would load up and auto-configure for all users. we had to provide post implementation support after migrating their mailboxes and changing their email profiles to connect to the new service. There was a mix of computers operating systems. Most were Windows 7 which were configured without many issues and there were also a handful of Windows XP systems. Most configured without issue but we had a desktop that needed serious extra support. it just would not connect to the Office 365 email server. The Outlook profile would almost completely setup but would start prompting for credentials which we were one hundred percent sure were right.
