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 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 :)

Can anyone recommend a very simple (preferably low priced or free/open source) solution for inter-office chat?  

I'm looking for ultra simple: just the ability for about 15 employees to quickly have simple chat sessions with each other over LAN.  No need for Internet connectivity, phone, or video.

I've looked at a few solutions, but I haven't found anything that I'd feel good about sharing email addresses with.  I signed up for one as a test and got 3 emails in 24 hours.

Ideally I'd like a utility that runs in the PC system tray, and you just quickly open it, send a message to a pre-set up user on the LAN.  No bells and whistles needed.

Anything safe like that exist?

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

A Microsoft Outlook 365 account in our company has reached the 50 GB limit in its PST file and it stopped receiving messages. This is what I did to free space:

a) Archive all the data from year 2017
b) Archive data from January to June 2018

Now I can see that there are 2 (archived) files that sum about 25 GB but the original PST file size has not changed so I ran the Compact tool but it seems nothing is done because it finishes instantly. I click Compact and it terminates "instantly" and the size of the file remains the same.

What can be happening?
Am I missing something?

I performed this same process in 2 additional accounts (some time ago) and it worked.

Using Exchange365 I trying to stop phishing messages that spoof the CEO's address. We have a rule set up for it but it looks wrong.
We have this set up in Exchange admin centre, protection, spam filter.

Applied to:
If the message:
Is sent to 'theceo@xxx.xx' or 'theFD@xxx.xx'
Take the following actions:
Apply hosted content filter policy "test".
Except if the message:

What I'm trying to configure is if the mail comes from an address where the name is 'theceo' but the mail address is not from our organisation.

Any ideas how this can be done?  We have Exchange for Business so don't yet have the enhanced anti-spoofing yet.
One of our exchange user is getting this error. Can anyone tell whats happening? Any workaround ?

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?
Hi, have an Exchange 2010 Hybrid setup

I have created distribution list in Exchange console and also distribution group in AD

Synced successfully, tried to send a mail to test@test.com

Get following error

The action 'Set-DistributionGroup', 'RequireSenderAuthenticationEnabled', can't be performed on the object 'media.queries@rtb.ie' because the object is being synchronized from your on-premises organization. This action should be performed on the object in your on-premises organization.

Have unticked Require that all senders are authenticated in Message Delivery Restrictions as sent a test mail and get below error

The group test.test only accepts messages from people in its organization or on its allowed senders list, and your email address isn't on the list.

Any best way to fix it?

New distribution group for a customer not working, they have hybrid on premises setup (Exchange 2010)

With distribution security group in Exchange On Premises,

I realise there are two groups

  Mail-enabled universal distribution groups (also called distribution groups) can be used only to distribute messages.

   Mail-enabled universal security groups (also called security groups) can be used to distribute messages as well as to grant access permissions to resources in Active Directory.

This is a universal security group, there is a group in Office365 setup, users are complaining that no one is receiving mail through the distribution group

Is there a checklist I can use to go through this? Just want to check the validity, someone else would have set this up, I've been added to support for our Office365 group and want to learn fast and troubleshoot this and see the best way to do this

Thanks in advance :)
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.
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 an NEC DT700 series phone. I think specifically it is a DT730.

Right now the message light is blinking, but the voice mailbox is empty.  It also has "MSG >>>" on the screen.

There is "Frontdesk" as the identifier, but I cannot clear that off.
I have a stand-alone Exchange 2013 (CU11) server.  All has been well for about 2 years now with all mail and any mail flowing well inbound and Outbound.  We do use Trend Micro Hosted Email Security for Inbound filtering.  As I just mentioned, we never had any issues with messages staying in the queue up until 5 days ago.  


1.  ALL inbound email is fine and flowing nicely.
2.  A handful of email domain suffixes will not go through.  For example, one of them is OUTBOUND mail to Sympatico.ca never leaves the Exchange Queue (also same with Bell.net and a few others).  90% of other outbound emails to other domains go through just fine.
3.  Tested DNS and appears to be resolving well
5.  Restarted the Transport Service numerous times to no avail
6.  No smoking gun in the Event Viewer
7.  Not using a smarthost on my Send Connector, using "MX record associated with recipient address" for delivery
8.  ISP even added a PTR record for my MX record.
9. get-ServerComponentState returns everything as Active

Really not sure what else to try or what typically causes only certain outbound email from specific domains from leaving the queue...  Here is what I see from one of the messages stuck in the queue (with replaced company specific info)...

Need a YouTube based webinar, with chat service

I need to create the MP4 of a live webinar, where I use OBS to live stream myself to YouTube, with my green screen replaced with a professional looking image. But I need one to many chat services.

So, how much I do this?

I wish I could use a comprehensive webinar solution, but they either do not support the green screen technology (WebinarJam) OR they are too expensive (GoToWebinar).

So, my solution is to use:

1) OBS for green screen removal
2) Live OBS stream to YouTube
3) YouTube handles audio

But I need a chat service my attendees can use to submit comments and questions.
