Troubleshooting Office 365 Multiple Prompts for Credentials

If you've ever connected a workstation to Office 365 and then been constantly prompted for your credentials you know how frustrating it can be.  Have you ever checked that box in Outlook to "Remember Password" and then screamed in frustration as yet another logon prompt came up?

We're with you... lots of us!  I've had a look around at the various resources for troubleshooting these issues and brought them together.  This is by no means an exhaustive list, just some links that I've found useful.  If you have suggestions to add I'm all ears.  I hope the list helps!

  1. Great list of resources Scott. Well done.

  2. this one worked for me:


    Removed all files and subfolders and afterwards I was able to save my passwords (4 profiles with email accounts on POP3 servers).

    I had the problem on a clean installation of Windows 8 and Outlook 2013.

  3. I'll check that out. Thanks for sharing!

  4. Is there any way to have a silent log-on with your existing AD account like you would have with Exchange on premises ?

    1. That's single-sign on (SSO). Using ADFS you can log on to your computer and then when you open Outlook 2007+ you don't need to provide credentials again. ADFS does require you to set up a new server (at least one) and some software though.

      In the next couple months you'll also be able to use Directory Synchronization to not only copy your AD objects to Office 365 but you'll also be able to use it to copy your passwords to Office 365. In this way, you'll have a single password across AD and Office 365.

      Does that help?

  5. I'm not sure whats going on. We can sign on using Firefox, Safari and IE. Although, when using Chome you cannot log in. I know we are using SSO and i've tried adding the "--auth-server-whitelist="*" but it does absolutely nothing. Maybe I am adding it wrong?

    1. I'm not surprised you're having trouble with SSO on Chrome. For the most part all modern browsers are supported, but it seems like especially with Chrome there are some anomalies.

      I'd advise just using another browser. IE 9 and 10 have come a long way and features are on par with the competition. It's a pain to use multiple browsers but that's the reality of the web today.

  6. We were having the same issue(asking for credential 3 times) when using chrome. We are not a federated/SSO site but are using the directory sync tool with password sync. We finally figured out that if we point our user's to it works perfectly fine in chrome, no 3 login attempts or anything. Originally we were pointing our users to and have recently updated our links to the url.

    Hope this helps with federated sites as well.

  7. Having tons of issues with Outlook2007 setup. If we take the same computer and upgrade to Outlook2010, it works fine. I have applied patches above for 07 and same result. Wish M$ was more clear on all patches needed for Outlook client.

  8. I faced similar issues with Outlook PST file in MS outlook 2010. Then I tried Stellar Phoenix Outlook password recovery software. Finally, I got lost access with Mailbox emails in Outlook application.
