Microsoft Training and Certification Team announced an update for the retiring date of the Lync 2013 exam.
A while back we announced that Skype for Business exams are coming soon and that the Lync 2013 exams would retire in November. We’ve decided to remove the retirement date for now while we wait for the new Skype for Business exams to release. Once the exams release we’ll announce a new retirement date for Lync exams 335, 336, 337, and 338. The new retirement date will be at least eight weeks post the release of the new exams. We expect the Skype for Business exams to release in December 2015 or January 2016.
