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).

iOS 12.1.2. This AM when I attempted to attach a YouTube link to a message via the iMessage app--nothing happened. That is, YouTube wouldn't load in messages, though I can open it via the "basic" screen icon, and download links from vids I open there into messages.

Yes, I closed and reopend the Messages app. Yes, I rebooted the phone. Yes, all other message apps work.

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
Need steps to configuration integration of Skype for Business 2015 with Exchange 2016. Already have the integration running between Skype for Business 2015 and Exchange 2010.

Have introduced Exchange 2016 in same Exchange organization need to SfB integration for exchange 2016 as well.
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 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

Running a virtualised platform on windows server 2016.  We have a requirement to remove all logon Status messages from the logon.  I mean everything.  Security challenge, Welcome to windows etc.

We have already tried the registry entry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\DisableStatusMessages, But this appears not to work on 2016.  

Can anyone tell me if this has changed in 2016 and if so what replaces it?
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? I want to prevent the client from performing a HELD request to get location information when it first registers to the server. Is this possible with the on-prem 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.
One of our users has had an issue where his computer will restart unexpectedly, and upon restarting, the settings page in chrome for incompatible applications opens up. The first time it happened, the application listed was an Intel driver, which I applied an update to. It has since happened several times, and still shows the Reset and Clean up page, but now with no incompatible applications show up. The user has not been doing anything out of the ordinary, and there are no windows error messages, save for an unexpected shutdown flag in the logs (ID 6008).

I have some messages from email I want to get in readable/audible form

I need to know the available SWIFT Message Parsers for reading unstructured BLOB and structuring the data into XML or some other format.

I did my research and found a few to name below but wasn't convinced if they are enterprise level and scalable.

1. Informatica has a tool to extract messages but it has limitations.
2. Data Transformation SWIFT OOTB library.
3. Volanté
4. Paymentcomponents ( parser is easy to use and finds all errors.

Any thoughts?
Thanks in advance.

I have a "Contact Us" form where customers can email us to get product information.  It seems like I must have a gaping hole in the code that allows people/bots to append long messages.  I was writing the customer data to a table, and I had a text field for extra information.  Despite several honey pots I was getting a regular stream of bots filling in the text field.

I'm not doing anything with my db and I have removed the text field, but I still things appended to the form.  Attached is the latest example.  I have also attached the Contact Us page that is having the problem.
Good afternoon, we have trouble creating a conversation with more than 3 people. The Skype version is 2015.
Can you help us?
