Outlook Keeps Asking for Password Credentials
When Outlook is configured for Office 365, the type of authentication is Anonymous Authentication.
For all of you that have been configuring Outlook know that this is not a normal option for Outlook authentication against an Exchange server. We normally have, as shown below, many more options.
Anonymous Authentication is not listed or available as an Option in Outlook
The anonymous option is present in Outlook 2013 but Outlook 2010 and Outlook 2007 do not normally have this option listed. windows 7 is normally not a problem but since there are still many Windows XP installation out there that we need to still support, this can be an issue.
Outlook Keeps Prompting for Credentials
So the problem you may encounter with some XP desktop systems that still need to be supported is that Outlook 2007 or Outlook 2010 will not have this option by default. You may find on forums a repeated suggestion to update the operating system. This is not always a good option as it might break another application installed already or you have already updated but still do not have the Anonymous Authentication option in Outlook. This Outlook issue can be resolved by IT departments remotely. Software applications that give IT departments remote access to computers through the web enables faster assistance because online desktop support software creates connections to the desktop. Software for online support is designed for faster access to user desktop computers to resolve issues.
I had a customer with XP SP3, Outlook 2007 which I upgraded to Outlook 2010 and applied SP1 but still no Anonymous Authentication in Outlook. I did not run anymore updates. Instead I found and ran the following Hotfix from Microsoft (I ran the 32bit version) :
KB Article Number(s): 2791026 Language: All (Global) Platform: i386 Location: (hotfixv4.microsoft.com/.../462115_intl_i386_zip.exe)
KB Article Number(s): 2791026 Language: All (Global) Platform: x64 Location: (hotfixv4.microsoft.com/.../462116_intl_x64_zip.exe)
After running this fix, Outlook would not start until the system was rebooted. Once the system came back up, the Anonymous Authentication option was available in Outlook 2010 .
Here is another information post regarding Outlook prompting repeatedly for user credentials.

Thank you very much for this post. It has saved me a great deal of time . I wish I had found it sooner and saved more time. 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.
Thanks, this saved me a lot of time. We were are supporting a migration to Office 365 and encountered this problem on a desktop that has Windows XP. 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.
There are some registry settings that can be tweaked that can assist in connecting outlook to an online server. 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.
running the hotfix from Microsoft worked really well, once I ran the hot-fix from Microsoft support the Outlook client had the Anonymous authentication available in the profile configuration.
