How to Undo Always Close All Tabs in Skype for Business with Screenshots

Skype for Business or Lync 2013 allows users to enable tabbed conversations where the chats are displayed in tabbed groups instead of separate windows. Tabbed conversation feature can be enabled or disabled by going into Settings > Tools > Options > IM and then choosing the option under “Enabled tabbed conversation” area. When in tabbed conversation mode, upon closing any of the conversations, the program prompts whether to close the individual tab or to close all tabs. This prompt appears each time a tabbed conversation is being closed. The user has the option to select “Always close all tabs” option from the prompt window. Doing so causes Skype for Business to close all tabbed chat windows in the future when the close x button is pressed, causing the user to lose all chat sessions. Many users wanted to undo the “Always close all tabs” feature but could not find the option in the settings. That is because, there is none. So, here are the steps to undo always close all tabs in Skype for Business with step by step instructions.
