Microsoft today announced that it is rolling out question and answer feature to all Yammer users. This feature will appear in groups and live events in Yammer over the coming days. Instead of posting questions as a regular post, the new Question and answer in Yammer allows you to start a conversation in the question format.
This new format helps others identify which posts need answers. In the coming weeks, Microsoft will also allow you to filter to see only questions and unanswered questions. An answer can now be marked as the best answer by the author or a group admin.
