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).

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.

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?

Thanks

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 :)

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.  

Scenario:

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.  

Suggestions?

Thanks

Does anyone have advice on how to add a basic messaging app into your web project?

I have a website and would like a simple in-app messaging feature - are there any good guides people have seen out there on how to execute this into a project - would PHP be good for this?

Any advice would be great!

I am receiving some emails from people I do not know.  In the To box my name is completely scrambled, the message is from a person I do not know and the subject is irrational
like 096-be?  there are links in the message but I dare not open them.  When I hover the mouse over the to box name and check the email address it is my email address.
What is happening here?  How does it happen and what should I be doing about it.  I have noticed this phenomenon with some other messages over the past 3 months.
thanks,

Exchange 2016 on-premises. Online Archive search results are limited to 250 items.

Exact messages reads, " Online results are limited to 250 items. If you didn't find what you were looking for, try again using more specific search terms."

I have read and applied the changes described for editing the Microsoft.Exchange.Store.Worker.exe.config in Exchange 2013 but that has not changed to behaviour in 2016.

Hi,

We have had Skype for a few years.

We are interested in purchasing Skype for Business and installing on a Windows 10 PC.

Before we do so, we would like to know:

- What are the differences between Skype and Skype for Business
- How much does Skype for Business cost
- Where to buy Skype for Business
- Can a person with Skype for Business call someone using Skype and vice versa
- Can the same Skype for Business account be used on any Windows PC in different locations
- Do we need an Office 365 account or can we use Skype for Business without it
- Can Skype for Business be used in a location with low bandwidth

We appreciate your support with the above.

Thanks,
Robbie

Hi Experts,

Could any one tell me what would it take to send Text Messages through PHP, both on the Server and PHP side?

I would prefer not to use third-party, due to sensitivity

Thank you.

I have a FB messenger conversation with someone. There is a setting that lets me delete the conversation. Does it delete the conversation on both ends or just my end? Since there could be some data in the conversation that the friend might have wanted to keep.

Windows Server 2008 R2, member server running 2 SQL 2008 databases, one is a CRM product (Junxure). Recently users started experiencing extremely slow access when connecting an email to an action in the Junxure client. The vendor says the problem is a folder that holds the email messages (.msg files). There are over 462,000 files in that folder (no subfolders), when on the server and opening that file the CPU utilization goes up about 40% for about 20 seconds until the files are listed which I would expect. When a user tries to open one of those messages in Junxure it can take over 10 minutes to open, the user can't do anything in the application until the email opens. The vendor says nothing they can do, maybe more ram will help but they aren't sure. They don't think it's SQL because all it's doing is opening a file, not an SQL function. We may have hit critical mass but we can't move any files out, vendor says it will break the links in the software. They just say most people upgrade to the cloud version at this point. We are scheduled for a new server and possibly new CRM software in 3rd quarter 2019, it won't happen before. I suspect some client files can be archived but they are reluctant to.
My first thought was more ram as well but I'm trying to figure out if that really will help, resource monitor shows it has 53% used physical memory. RamMap shows 6gb of unused ram. It has 16gb, I can double it to 32gb. I've not used RamMap before so maybe there's more it can tell …

We use Skype for Business but we're currently unable to review the chat logs and receive mobile updates (for instance, updates to a group conversation) on our mobile devices.  At my last place of employment I was able to do both.  My question is, are there some changes to our environment we would would need to make in order to enable both features?  For instance, will these features ONLY work if there's some sort of VPN client running on the mobile device?  Does the customer have to host Skype internally?

If there's a URL that describes the requirements I'd be glad to review them.

Thanks.

Users are being forced to upgrade to latest skype client, currently v8.25, but from what i can see the user is not able to increase the chat text size.   This is troublesome and a backwards step for particularity elderly people using 1080+ screens.  

Skype (version 7) for Windows will stop working soon. Update to the new Skype (version 8) for Windows today! Don’t miss out on exceptional HD video calling, 300 MB file transfers, the ability to tag contacts with @‍mentions and more. Upgrade to the latest version of Skype to seamlessly transfer your sign in information, contacts and chat history. For more details and help, visit this page.

Does anyone have a hack/workaround for the text size?   If Microsoft have not built the setting into the initial design I can't imagine they will be adding it anytime soon.

Thanks,
--Paul

I received what appears to be a scam email today.

I am aware athena is your password. Lets get straight to the purpose. You don't know me and you're probably wondering why you are getting this e-mail? Neither anyone has paid me to investigate you.

actually, I setup a malware on the xxx streaming (adult porn) site and do you know what, you visited this site to experience fun (you know what I mean). When you were viewing video clips, your browser began working as a RDP with a key logger which provided me with accessibility to your display screen as well as cam. Just after that, my software collected all your contacts from your Messenger, FB, and e-mailaccount. And then I made a double-screen video. First part displays the video you were viewing (you've got a fine taste haha . . .), and next part displays the recording of your cam, yea it is you.

You got two different alternatives. Why dont we go through each of these choices in details:

Very first choice is to neglect this email message. In this situation, I will send your very own tape to every one of your contacts and then think about concerning the humiliation you feel. Keep in mind in case you are in an affair, precisely how it would affect?

Next choice is to compensate me $1000. We are going to call it a donation. In this situation, I most certainly will promptly eliminate your video recording. You can carry on with your way of life like this never happened and you will not hear back again from me.

Exchange 2010 stops processing messages in and out until reboot.      This error occurs in the log around the time of the failure.      Even 1009.    Details are The Microsoft Exchange Mail Submission service is currently unable to contact any Hub Transport servers in the local Active Directory site. The servers may be too busy to accept new connections at this time.

Its worth noting we have a hybrid deployment as we are slowing migrating to office 365.      We did not have this issue prior to hybrid setup.
