Resolved: PSU Yammer Users Unable to Log In

Last updated on May 1, 2015 at 9:54AM

Update on May 1, 2015 at 9:36AM

A possible fix is in place and active and we\'re monitoring the situation to make sure all is well. All users should be able to log in from all of their devices. We will resolve this alert once we are sure the service has returned to normal.

Update on May 1, 2015 at 8:27AM

As of 6PM on 4/30, Microsoft and Penn State are still working to resolve the current log in issues and testing possible resolutions. More information will be provided as it becomes available.

If you are currently logged in to Yammer on any device, it is advised that you not log out. This should still allow you to use Yammer as normal. If you have access to, and have previously used a mobile device to access Yammer, it is suggested that you try using that to access your messages. While mobile devices are not exempt from this log in issue, it may be the case that your mobile device has not logged out of Yammer and thus would not have issues authenticating.

Update on April 30, 2015 at 12:32PM

We have been in contact with Microsoft and have identified possible causes to this incident. At the moment we are looking into various fixes and will keep you updated on any progress.

Update on April 30, 2015 at 10:29AM

At the moment it appears that users who had an active Yammer session open over night are still logged in and able to access Yammer. New logins are unable to connect. If you are currently logged in, it is suggested that you do not log out. New logins will fail at this time.

Original Alert

Penn State Yammer users are experiencing intermittent errors when logging in to Yammer. Some users are able to access the service at this time, while others are not.

The cause seems to be that Microsoft recently upgraded their backend Identity Provider, which is causing problems for some Penn State users when logging in.

We are aware of the issue and currently working with Microsoft to resolve the problem.

For more information, please contact Derek Gittler (dcg163).
