Lync 2013 Full Client Disconnecting and Reconnecting at various times
Posted on 2015-01-23
We are using Lync Online with the Lync 2013 client from Office 365 Pro Plus. The issue we have is the Lync Client will show "disconnected" and then "reconnecting" every so often (this can vary from every 10 minutes to once an hour) All users are seeing this issue. The user does not need to input anything in order to reconnect, the Lync Client will do it automatically.
Now, I think I know the issue of the disconnect/reconnect. We use a TrendMicro Web Filter internally (version 6.0, SP1) When we BYPASS the Trend device, the disconnect/reconnect issue DISAPPEARS. When we re-enable it, it comes back. We added all the O365 URL to the exception list, but it hasn't helped. We opened a ticket with TrendMicro and they are looking at it, but I am wondering if anyone else has seen this before, and if so, what they did to resolve.
Thanks in advance,
