  • Hello,

    We are getting reports of some users receieving duplicate IM messages in our Skype for Business 2015.

    For example a user will send:


    How are you

    and the recipient will get:

    This is a bug that was introduced in the November update for the Skype for Business 2015 and 2016 clients.

    The estimated time of arrival for the new updates that resolves the issue is sometime in January.
