Skype is not saving history conversations skype for business 2015

For this problem there some workarounds but they are only temporary solutions, here you have all that I have tried:
1.      Delete the oldest file in the conversation history folder (%userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\sip_EmailAddress\History Spooler) restart outlook and it going to work again.
2.      Re-create the skype profile, first sign out and exit from skype and outlook, then go the follow path “%userprofile%\AppData\Local\Microsoft\Office\15.0\Lync\” rename the current sip_EmailAddress (you can add _Old) open skype and outlook and it going to work again.
3.      Update the skype for business client.

But the most recent fix is modify the exchange server file web.config. it means open this file from installation directory > Client access > EWS. Edit web.config file and add this line (Preferably type it instead of copy & paste): Restart IIS and it works again.
I hope it helps

Problems with attachments and vbscripts in outlook

If you have an issue with attachments in outlook (any version) basically when the attachment includes consecutive dots (…) or exclamation mark (!) the files are blocked and you receive an error message: “Opening mail attachment. You should only open attachments from a trustworthy source”


If you have problems with a custom form that you have created for outlook and see one of these messages:
“To help prevent malicious code from running, one or more objects in this form were not loaded.” or the vbscript doesn’t run.

The fixes have been releases from Microsoft last Friday July 28. Go to this website and find the correct KB according to your office version.

how to know what port and connections are in use

With the command Netstat we can know what ports are listening and therefore we can troubleshoots some applications, with this command we are able to get protocol statistics (for UDP and TCP v4 and v6).

If you use the command netstat without parameters only display the active connections, but sometimes you need to know about a specific port, in this example you can use the parameters -a -n -o

C:\>netstat -ano | findstr 80
  TCP               LISTENING       4
  TCP              LISTENING       2436
  TCP              LISTENING       1080

and you will obtain what process ID is listening in the port 80 and which protocol as well.

this is a complete list of parameters to use with this command.

Displays protocol statistics and current TCP/IP network connections.

NETSTAT [-a] [-b] [-e] [-f] [-n] [-o] [-p proto] [-r] [-s] [-x] [-t] [interval]

  -a            Displays all connections and listening ports.
  -b            Displays the executable involved in creating each connection or
                listening port. In some cases well-known executable host
                multiple independent components, and in these cases the
                sequence of components involved in creating the connection
                or listening port is displayed. In this case the executable
                name is in [] at the bottom, on top is the component it called,
                and so forth until TCP/IP was reached. Note that this option
                can be time-consuming and will fail unless you have sufficient
  -e            Displays Ethernet statistics. This may be combined with the -s
  -f            Displays Fully Qualified Domain Names (FQDN) for foreign
  -n            Displays addresses and port numbers in numerical form.
  -o            Displays the owning process ID associated with each connection.
  -p proto      Shows connections for the protocol specified by proto; proto
                may be any of: TCP, UDP, TCPv6, or UDPv6.  If used with the -s
                option to display per-protocol statistics, proto may be any of:
                IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, or UDPv6.
  -r            Displays the routing table.
  -s            Displays per-protocol statistics.  By default, statistics are
                shown for IP, IPv6, ICMP, ICMPv6, TCP, TCPv6, UDP, and UDPv6;
                the -p option may be used to specify a subset of the default.
  -t            Displays the current connection offload state.
  -x            Displays the TCP connection template for all connections.
                Cannot be combined with the other options.
  interval      Redisplays selected statistics, pausing interval seconds
                between each display.  Press CTRL+C to stop redisplaying
                statistics.  If omitted, netstat will print the current
                configuration information once.

How to configure Telerik Fiddler

Telerik Fiddler it’s a great tool for troubleshooting, you can see in real time whats going on with all connection, for example I’m having a problem saving conversations history in outlook with my skype for business client.

I have configured the Fiddler to trace from the client with HTTPS decryption, it easy just go to Tooll Menu – Telerik Fiddler Options – HTTPS Tab and check “Decrypt HHTPS Traffic”.

Yo can find the complete manual here download and enjoy this great tool.
