Microsoft has decided to discontinue Skype 7 due to a newer version 8. This will take place from November 1st and beyond. Read more about why here.
This applies to normal Skype , not Skype for Business, you can read about the differences between these two here.
IT NMBU will therefore start rolling out new Skype 8 to employees, so that users who have lost their old features will get them back again. More info about Skype 8 can be found here.
