Outlook/Office 365 Authentication Issue:

A change was implemented yesterday afternoon by our email providers that has caused many users of Outlook and Skype to be prompted for their UWNetID credentials in order to log on to their Outlook program to access their UW Office 365 mailbox. If you have been affected by this issue, please note the following information:

  • For users who view only one UW mailbox with their Outlook, simply re-entering their UWNetID credentials will restore access to their mailbox  (Note: this may require you to close and re-open Outlook on your computer)
  • For users who have configured their Outlook to look at multiple mailboxes, unfortunately this prompt is not specific which mailbox it wants credentials for. Currently, the only method to resolve this to try the log-on credentials for ALL the mailboxes your Outlook is configured to view. Once you have successfully authenticated to all mailboxes, your Outlook should function normally.
  • For users of Skype, re-entering your UWNetID credentials into the prompt should restore your access to this service. 

Our providers are aware of and working on the problem. If you are not able to restore access to your Outlook using one of the methods above, we recommend the following work around:

  • Access your email using any browser using webmail at this address:

We will continue to monitor the resolution of this issue and report updates on this page and through nball.

Thank you for your patience and understanding.  

If you have any questions at all, please don't hesitate to contact the UWB IT Helpdesk.
