Unitrends and Office365



  • So just got official word from Unitrends that Office365 is supported by them. They said it will work natively. The issue by default is they have 25 as the SMTP port and it obviously needs to be 465 for Office365. So, that being said, change one setting at the CLI level and use the normal setup means for email reports.

    Have you tested it out yet?



  • I tried some but was unsuccessful in getting it to work. Further testing will proceed soon.

    TLS has to be used.



  • I'm aware. The problem is that by default UT uses port 25 for SMTP by default. I found in the installer's access KB an article on how to set it to 587. So, in theory, after changing the port, you should only have to use authentication for the email server of smtp.office365.com and I'd assume it'd use TLS but it was unable to get it working.


  • Service Provider

    If all you did was change the port, how could it be using TLS? Unless you are turning TLS on, it's off.



  • @scottalanmiller I am going to have to look into that. I'm not sure how you'd go about doing that on a UT box...

    Last I knew, it wasn't supported.



  • @scottalanmiller And that's what everyone is saying. I'm getting different stories from higher ups though. They say it works with UT's O365 but they are using some sort of weird relay and I'm not sure what it is. Going to have to look into it some more.

    It's a relay, plain and simple. We know that that works. "Using a relay" is a term of "it's not supported." That means that you have to build a proxy email server that handles Office 365 on UT's behalf because UT doesn't support it. It's like how 12 year old's are "able to drive a car" meaning "they can be a passenger in a car that someone else drives."



  • @scottalanmiller I'm aware. I've had it insisted to me that it works but a lot of installers are saying it doesn't. I'm pretty sure it doesn't but will try a couple more things to confirm before I go back and confirm it still doesn't.



  • What is it about companies making products that still don't natively support email over TLS? come on people it's security. SIGH!



  • @Dashrender I know. It's silly.

    I didn't see it here, but did anyone mention that updates to the Unitrends appliance will also reset the default port 25 for SMTP? If you use the work-around, you'll need to repeat it after every time you run updates.

    "It works with a relay" is marketing for "it's not supported yet". You just have to learn to hear when someone says something that sounds positive on the surface but is actually a negative. They were telling you that it doesn't work.

    You could use a script or a tool like cfEngine to override that. But it is extreme the degree to which it does not support Office 365. Far more than just lacking support. It actively breaks it. The OS itself supports it.

    Bottom line is: create a gmail account and fwd it to your 365 account. Works all the time. Not a "correct practice" solution, but that's what there is.



  • @scottalanmiller I think your point about turning on TLS is valid. I need to see if there is a way to do that. These all seem like really easy things to just make easier. An input box on the settings page for SMTP that allows you to specify the port number and set TLS as enabled/disabled would not be that hard...

    Really? You shouldn't have to enable it - it SHOULD be enabled by default to try it first - if it fails than go to non TLS. It's not like most mail servers aren't using TLS on a standard port (those that support it).



  • @Dashrender I am not sure about that but if it's on port 25 that would indicate to me it's off by default. FWIW

    By your own discoveries and what @scottalanmiller has said - it does not appear the unitrends box even supports it at all. So I'm sure you're right - it's off because it's not there :P



  • @dashrender Yea, it's just weird because I've been told by the installations technical lead specifically that it works on their system (they use Office365) but again, I believe that they have a relay setup and he may be confusing that. Other senior installers that I've talked to have said they aren't aware of it being supported at this time. shrugs

    That's not what you said up above. When you quoted them they very implicitly said that it did not support it. You then changed the words around and said that it did. You've delivered two different messages from them. If they said "relay" then they clearly told you that there was no support.


  • Service Provider

    The relay is everything. It's like saying you car can fly.... When you pack it in a crate and put it on an airplane. It's the airplane that flies. The car is cargo.

    Unitrends supports the relay, but not Office 365. The relay supports Office 365.

    The installers themselves (several) confirmed what I was understanding which was that Office365 is not supported at the moment.
    The installers technical lead was adamant that it is as he said they are using Office365 native with their internal appliances. He server he posted though for what they use wasn't smtp.office365.com. It was a bunch of subdomains ending in outlook.com so I'm going to assume it's a relay. He also posted in the chain a KB (internal only at this point) article that shows how to change the port from 25 to 587. So far I have not been successful at getting it to work so I feel that kind of confirms my relay theory and that he may be mistaken in his understanding of possibly how it was explained to him or how he interpreted it. FWIW



  • @scottalanmiller I understand. But he was saying that changing some settings was supposed to allow you to use Office365 like someone uses their on-premise Exchange, which is confirmed to work natively no problem (on-premise Exchange). That's what I'm saying.


  • Service Provider

    Email support has always been an issue. Would not be surprising if they weren't aware of what was or was not working.

    We've reported in SW and it was confirmed not to be working. So, in theory, they are aware.

    Even on premise doesn't work properly. You have to disable security for it to work. Office 365 just doesn't allow to violate that best practice.



  • @scottalanmiller I've never seen you have to disable security for on-premise Exchange. I would know. :P

    You do. Obviously, as the issue is lacking TLS.
