Lync 2013 Full Client Disconnecting and Reconnecting at various times

Hello:

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,

Tim

Were you able to find the resolution for the disconnect/reconnect problem yet?
I had to deal with something similar with SEP client and there was a condition check built into the client to discover the protection manager and if the user doesn't connect to the vpn within the defined time interval the SEP client would basically disconnect the network interface and then reconnect once the defined time interval is lapsed.

The resolution end up being to manipulate the condition check built into the SEP client for the protection manager discovery and also exclude Lync.exe process from the SEP firewall.

No..Trend admits it's an issue with their product but they have no solution at this time.  They don't use SEP...

Do you have any kind of network threat protection or intrusion detection/prevention feature turned on in Trend?

No, the issue is the Trend Proxy feature...it has nothing to do to with the Firewall or other Intrusion Detection.  Like I said above, Trend knows the issue is with their product, but they have not issued a fix as of yet....So, temporarily we bypass the Proxy and everything works normally.
