Sporadic Login Issues with Yammer
A number of users are reporting difficulties logging in to Yammer. At the moment, ITS is still trying to determine the cause. If you are experiencing log in issues, please contact the ITS Service Desk with the following information so our Yammer second-level support can troubleshoot this issue:
1) Your location (if on-campus, the building and room; if off-campus, just off-campus)
2) The type of system you are using (ie. Macbook Pro, PC using Windows 7, iPhone)
3) How you are accessing Yammer (ie. Yammer app, Google Chrome, Safari, etc.)
