Chat / IM

Instant messaging (IM) is a type of online chat that offers real-time text transmission over the Internet. A LAN messenger operates in a similar way over a local area network. More advanced instant messaging can add file transfer, clickable hyperlinks, Voice over IP, or video chat. Non-IM types of chat include multicast transmission, usually referred to as "chat rooms". Depending on the IM protocol, the technical architecture can be peer-to-peer (direct point-to-point transmission) or client-server (a central server retransmits messages from the sender to the communication device).

I have created a rule to add a warning message for all external messages coming to  Exchange Online. The rules is not working for any of the test users,  no warning  is attached to new external message, I waited for  more that 24 hr without any positive result.  All  the users are cloud only in the Office 365 tenant. There is no Exchange on-prem and no local AD.   What else do I need to do to make the rule MAIL-RULE-FAILED.docx work? Thank you.

whats the best way to make an app that recieves messages from udp port (string )  convert into and object  and send it to a  db  by store procedure . using .net or .net core   ... is favorable to use MSQM ? (using a buffer ?) or  is way better to use  sql server vs MSQM .. what about MSQM over WCF ? ane suggestions.  .. it means  massive (5000+/sec) messages    and convert it  to an object and  use a store procedure
At work,  when documents need to be scanned and saved by our imaging department, employees send the documents to an email inbox. This is a dedicated inbox that exists for the sole purpose of receiving emails with attachments that need to be imaged. I manually save the documents to a folder on a shared network drive based on contents of the subject line that determines the document category/folder it goes in. I want to automate this with vba so emails & their attachments are saved on the network drive on arrival.   Email messages themselves require saving even if without attachments.   I'm using office  2016, 2110
 I try to send messages to lock screeen  in windows 10 through my uwp application

according to this

I have create on button click event

 private void button_Click(object sender, RoutedEventArgs e)
            Microsoft.Toolkit.Uwp.Notifications.TileContent content = new Microsoft.Toolkit.Uwp.Notifications.TileContent()
            Visual = new Microsoft.Toolkit.Uwp.Notifications.TileVisual()
                LockDetailedStatus1 = "Meeting with Thomas",
                LockDetailedStatus2 = "11:00 AM - 12:30 PM",
                LockDetailedStatus3 = "Studio F",

                TileWide = new Microsoft.Toolkit.Uwp.Notifications.TileBinding()


        var notification = new TileNotification(content.GetXml());


Open in new window

but nothing happens when I click the button no errors no message. I have declare my app so to be used on background in Package.appxmanifest and I have also select
Control Channel, Push Notification and Timer in Declarations.

Any idea or other way to send notification to lock screen?

thank you!
Emails from my mandrill smtp server to myself are being rejected as a soft bounce.  How can I resolve this?  I rely on these emails for error messages from my websites and other things.  I can get email at this account but not if it was sent from my website using my smtp (mandrill) server.  Any help would be much appreciated!  Note that the email account is hosted at GoDaddy but I can't find a setting there to fix that.
I am trying to develop an API call to to retrieve my "token" so I can begin uploading products.  I have referenced the developer docs below, but I keep getting error messages. Is it necessary to really add the spaces and line feeds, or is this just for readability. Trying to get past step one. Any help would be appreciated. Thank you.

I am using Visual Studio Community 2017/C++ and AGK Trial 2 to develop GUI apps. The Console output nor the VS output don't show any debug messages, whereas the exact same code worked fine with Visual Studio 2010.  To start with I  used an AGK template VS2015 project and inserted my old working AGK code to it. It builds and runs perfectly in VS2017, but the Console doesn't show any debugging messages printed with "cout", as it did when using VS2010.   The following code  is the function I used to pop up the Console:

// for the console to display "cout" outputs, all these must be included
// And later these should be removed when you program is fully debugge
#include <Windows.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <direct.h>
#include <fcntl.h>
#include <io.h>

void console_back()

int hCrt;
     FILE *hf;

   hCrt = _open_osfhandle(
             (long) GetStdHandle(STD_OUTPUT_HANDLE),
   hf = _fdopen( hCrt, "w" );
   *stdout = *hf;
   int i = setvbuf( stdout, NULL, _IONBF, 0 );


// in the main code
cout << "Hi, Hello World";	

Open in new window

As is see in the attached snapshot, the Console pops up but stays blank, though the is no runtime complains from the
system about the cout << "Hi ..".  

Experts, any ideas why this happens?  I hope there is a workaround for this problem, sample code is highly appreciated.

A side note, I am using a trial version of AGK package, where I don't have a debug version of AGKWindows.lib so I can't
build VS2017  in debug mode.  This makes debugging with console messages the only option for right now.
After all as long as I have a way to debug, I will be happy. But I don't know if the retail version of AGK  has the debug version of the AGKWindows.lib in C++.  Any comments or suggestions along this avenue are also appreciated.


My objective is to find a collaborative meeting space where people can communicate with other members around an agreed upon topic without having to adhere to a particular time. Despite this flexible structure, members should still be able to 'propose' a new meeting time and new discussion topics as-needed.

I have begun the sheet here with this purpose in mind and will add to it as more information comes in over time.

Dear Expert,

I have  client computers connecting to 1 GB speed access to switches 3750/3850.

These access switches connect to a pair of 6500 core switches. These go out to the SD WAN ISP, and they mark the Skype traffic, both voice and video.

I would like to prioritise Skype traffic on the LAN segment from desktop SfB client to the edge. We use SfB online only.

Would a class map suffice and any recommendations would be highly appreciated.

Many Thanks in advance

I AM working on implementing a push system with signalR.

We know that there are network outs, devices not online for some time etc.

I need to guarantee, a 100% exact sync of a server table, with the sqllight offline table.

I am going to combine webapi calls, lets say since last update i have recived, this is used when connection is dropped, or I have not been online for some time
and when i am online i am connecting with signalR, I will tr to buffer the feeds for max 1 hour, that when client reconnects he can reed the feeds from buffer.

Does anybody have any thoughts on this in general, or am i cracy starting this? Is theer the possibility that when signalr reconnects with same ID (not the case when connection is dropped after 90 secs, but reconnects within 30 secs -> these are the default setting for SR for reconnect and drop connection), that in a short timeframe messages will get lost, or does signalr resubmit them on reconnect.

basically: if these connections is sort of on off for seconds, and SR reconnects again, what happens to the messages.

I have a problem with my Exchange server ( Exchange 2010 installed on windows server 2008) .the problem is that I cannot send Emails to some domains.these messages on the Queue messages with this error message (451 4.4.0 primary target ip address responded with 554 5.7.1 delivery not authorised(reverse dns record missing attempted failover to alternate host but that did not succeeds either there are no alternate hosts or delivery failed to all alternate hosts) .
my dns server is forwarding queries to my ISP DNS server.and my exchange use my dns for send connectors.
I nslookup these domains and it resolves fine.but when I send to them via telnet it gives me an error message ( 550 5.7.1 unable to relay )
I have recently setup an SMTP relay to forward messages from one of our internal servers to the Outlook mailboxes of our ICT team, I can see from the SMTP logs from the mailroot folder on the servers C drive that the mails are all being delayed as they try to send.

in the logs the following message shows:

"This is an automatically generated Delivery Status Notification.



Delivery to the following recipients has been delayed.

I cant see any specific errors elsewhere in the logs that would point to what the cause is.

can anyone please advise?
Yesterday, we start to get complains from users that there is a delay in email delivery. Looking into it i noticed one of our exchange servers had over 50 K messages stuck in its Submission Queue. after flushing the transport Queue by restarting the transport service all the messages were released. However i am trying to pin point the cause.
I noticed in the Submissions Queue that there were thousands of messages with the senders address of Null <>. Which I believe that caused the Queue to be stuck.
Today I just got the message tracking log report of all messages that had empty sender for the past two days and I get 18K messages in two days with Null sender. 16K of them are  messages with the Event ID of  PROCESSMEETINGMESSAGE. What i am failing is to pin point what caused all these? any hint will be helpful :)

I have a user that new messages are not going to the user Inbox.  The user is using the owa in exchange 2010.  When the message arrive it shows in a folder under the inbox.  I have cleared all searches and I have reset views.  This also happens when I load the user ID in a outlook client on a PC as well.
I have very little understanding of what I am doing inside of my facebook business page and of course, there is no FB support help desk. People are messaging me inside my business page but I am not getting alerts. It appears I have all alerts turned on but I do not see any alerts via email or sms.

I have a personal messenger app on my iphone. Is there a way to have a business version installed?

How do you turn on SMS alerts when people message me on my business page?

thank you

In Skype for Business Server 2015, Is there a way to disable clients from retrieving location information from the LIS/Secondary LIS every time the client registers with the server?

Hi, is there a way in Office365/online Exchange to set a rule to delete messages with a particular subject line after 3 days for ALL users? I think I can do this with an outlook macro locally but would rather do it in o365/online exchange centrally for all users.
