I'll try to be clearest as possible as I think this is not a usual situation. If you need more details, please say it.
I work on a company that has an Exchange Server. They provide a laptop which is on company domain and I can connect in Outlook just fine with my company e-mail. If I go home with my company laptop I can connect via VPN to company domain and connect to Outlook just fine as well.
We have a webmail which we can use in ANY untrusted computer on browser, something like webmail.mycompany.com and I just need to put my username and password to connect.
I also have an Android smartphone which is not on domain as well and I can configure it to connect to my company Exchange mail.
However I work on a remote server which is not on company domain (I can't change the domain on the remote server) and I'm trying to configure Outlook on the remote server unsuccessfully...
I'm very confused and wondering:
If I can connect via VPN to my company Exchange mail on Outlook anywhere as long as I have internet access on my company laptop
I can connect to my company Exchange mail on a webmail on browser on any computer (not on company domain) providing username and password.
I can connect to my company Exchange mail on my Android smartphone (not on company domain) by providing the Exchange mail server, username, domain and password.
Question: Is it possible to connect to Outlook in a different domain on a remote server with the information I have?
Thank you!
If an Exchange server is published correctly with ActiveSync enabled, then an device that supports ActiveSync should be able to connect to it. I am contracted out to 4 partner organisations during the week, 1 orgs email is Exchange Online, the others are local exchanges, one each of 2007, 2010, 2013.
I can easily hook up my email accounts to each of these from my phones, outlook 2010 at home (not connected to the domain or VPN) and outlook 2013 in the office (that is domain connected). (For 2 of these orgs my first job was to correctly publish their exchange farm for their employees)
You mentioned a VPN tunnel, if you have to establish a VPN to connect to the exchange then it sounds like it has not been correctly published externally, possibly by design.
The first thing you should do is talk to your Exchange Admin and ask them to confirm or publish the Autodiscover and ActiveSync related services for the exchange you wish to connect to externally, it's quite secure by default and has been designed to be used in this way so you shouldn't get much resistance on this front.
If you are the admin, or just playing along at home, then your next stop should be the Microsoft Connectivity Analyzer https://testconnectivity.microsoft.com , previously testexchangeconnectivity.com... that uses the same protocols that outlook and mobile devices use to connect to MS Exchange, this includes Exchange Online.
If the connectivity analyzer can connect, but your client can't then download the client analyzer from the "client" tab in the connectivity analyzer site. The error prompts are really informative and help to improve your understanding of how the Exchange platform works
Outlook 2010 can only add one domain connected Exchange service at a time, but it can have many activeSync compatible services connected no worries at all. Follow the test results on the connectivity analyzer site described above for guidance, the two most common issues that I come across are:
You primary email alias may not match the autodiscover service. For instance user#email.com might belong to an exchange that is published as 'electronicemail.com' In this case you need to make sure you connect to the exchange service as 'user#electronicemail.com' your default replay to address as configured in exchange will still work as user#email.com, but outlook doesn't know about these details untile after it has established a connection to the exchange server via the autodiscover service.
The other common issue is that the autodiscover service is not contactable externally or does not resolve correctly when you are external. (this happens a lot with Small Business Server and Essential Business server) In these cases you can sometimes make some quick edits to your c:\windows\system32\drivers\etc\hosts file to direct outlook to the right server IPaddress to configure the account. If you add a hosts entry for autodiscover.yourEmailDomainName.whateveritis into your hosts file this can often get around issues caused by the organisations public DNS not being configured for exchange.
Note that the hosts solution above can work in many instances for both of these issues

More than a simple question-answer, this is more of a recommendation post. Want to see what ideas I have to work with. I am working on porting my company's work to the cloud (GCP) Most of this work is in the form of a pipeline. I'd like to notify completion via email.
The company I work for has a private network. And so the only way to use their mail config is to send it through their internet, and so, cannot use their SMTP-config from GCP.
What's the best way around this?
I'm looking into creating a VPN between GCP and our local network, however, that may not be possible (IT restrictions)
Do I have any other options?
EDIT
What an SMTP Relay work? This guy.
By default, Compute Engine allows outbound connections on all ports but port 25,so if you need to send an email from the instance you have to use port 465 or 587.
GCP explecitely recomends using other third-party tools such as SendGrid, Mailgun, and Mailjet because they offer a free tier package, you can skip all that and connect your instance to Gmail SMTP Relay Service. You will need a Google Account to connect (gmail or Gsuite).
Instructions to configure the Google Account are HERE , I tested sending emails from my MySQL server and Debian 9
When messing around with different mail hosting options I noticed a very aggravating pattern with my Android phone. Neither the built-in mail app nor the gmail app supported email auto-configuration.
When using most mail services such as Namecheap, Zoho, Rackspace, etc. this became a real issue. I would enter my email address and password then instead of it just working like magic, it would invariably fail as it attempted to set the mail server to mail.example.com instead of mail.privateemail.com or smtp.zoho.com
I can configure a CNAME entry for my domain to redirect to these servers and successfully connect to mail.example.com.... up until I try to enable secure e-mail (STARTTLS or TLS wrapper). When I do this the domain name on the certificate does not match up to the domain name I am using to access and the whole thing fails.
Of course setting up my own mail server could be an option, but it could take months or years for my IP address to build up enough reputation to not get auto-blocked by major providers like Gmail or Yahoo. This whole past month DreamHost has been unable to send emails to any address owned by AT&T, which has been nightmarish to get resolved. Not wanting an issue like that, I would like to go with a big name for e-mail hosting.
While looking into Amazon SES to see if it would be easy to set up, I noticed this page on secure tunnels to AWS SES
I'm not super familiar with mail servers and I honestly have no idea what I'm reading on this page. Like I can follow the steps to install and configure this program and run it, but it doesn't accurately say what the purpose is of doing this. Am I right in believing that this might solve my SSL issue and allow me to send mail to mail.example.com without any issues? If so, is there any additional setup that I will require which is not adequately explained by this article?
I'm currently using 1&1 and they have a system for managing emails. I need to make sure I don't lose access to my business site's email addresses. What can I do?
When you have application running in Windows Azure and you want to access your application with real domain name i.e. yoururl.com you actually don't transfer your domain. Your domain stick with the same domain registrar whoever it is (in this case 1&1) however you just use DNS or CNAME setup in Windows Azure application so your domain name point to actual application running on Windows Azure.
As far as I know if you are just setting your domain name via DNS/CNAME, pointing to Windows Azure application, there is no changed to your domain and it will intact with your domain registrar and will not impact anything else.
At last, I do have a question what are you doing with Windows Azure as you don't have better understanding about how it is impacting your when you are making decision, so you may need little more info/knowledge about what and why you are using Windows Azure and how it is going to impact your current setup.
Azure has no email system equivalent to that bundled with web hosting by many entry level providers (including, presumably, 1&1). You are either going to need to continue hosting your email with your existing host, or transfer your email domain to someone who offers pure email hosting. Another option might be to run your own mail server on a Windows Azure VM, but according to this post, this isn't yet possible due to networking restrictions: http://social.msdn.microsoft.com/Forums/en/WAVirtualMachinesforWindows/thread/18da4da3-ebf3-48c7-9462-12fa4317175b
I am looking for a little direction to my problem. Short story, I have a website hosted on a web server. I pay a yearly subscription. This year I am planning on taking it off and hosting it internally. I already backed up, restored, and installed all necessary components (on Windows BTW with IIS, PHP, and MySQL). The site works great internal and by IP address externally through a firewall. (IP address for now until my web host subscription expires, then I will forward and register DNS).
But now this is my problem, my website has email functionality which works on my providers server. I want to install a local mail server for my website that will wind up sending and receiving emails through my website. I am lost here. No sure which path I should take. I have installed and used Exchange 2003 in the past just for internal domains, nothing for internet AND internet.
Anyone with ideas, links, suggestions? I see that IIS does support SMTP virtual servers, is this a possible route? If so, what about POP3 or IMAP (incoming) server solutions?
Thanks
Edit
---Update On Situation---
So far I have configured a local exchange server that works with my local webserver. I then created a CNAME in my web host DNS zone for my IP address. I created a simple subdomain for my site redirected to my home web server. Everything works great, internal email through Exchange 2003 from website on IIS, redirected DNS names, almost there. Now I just need to create Internet Mail functionality in Exchange. Went through the Exchanges wizard to "open system" for Internet mail, created new SMTP connector and ....nothing for external mail test. Failed! Thought everything was configured properly. I also tried to open all ports on firewall, 25 and 110.
I'd recommend using something like PostMarkApp to send transactional email from the website, and use hosted email (Google Apps for Domains) for your email. Its a pain to run a real mail server.
Link to Exchange Internet mail SMTP connector configuration:
Configure Exchange Internet Mail SMTP Connector
Well, I did figure it out. I was on the right path and everything was working but I just configured my client wrong and my ISp blocked port 25, duh. CHanged port to unused 366. But here is a little tip for anyone that may need to figure this out in the future.
1)Setup install IIS with default SMTP and NNTP virtual servers.
2)Install Exchange into organization. Internal naming convention doesn't really make a difference between internal to externally if you are behind a firewall. Basically this means you don't have to create a seperate zone in DNS if using this for a seperate domain hosted elsewhere. Hope this didn't confuse anyone.
3)Right click on server name in Exchange System Manager and go to Internet Mail Wizard
4)If you want your clients to hold a different domain email address than your internal you can setup in exchange through
Exchange System Manager >> Recipients >> Recipient Policies
Then add a Masquerade in Default SMTP Virtual Server
5)Have a gmail Internet SMTP connector set to smtp.gmail.com as smart host with a gmail email account settings and TLS checked
6)Default SMTP VS set with outbound port 587 and TLS checked
If you need to change SMTP ports too, don't forget to change not just firewall but also inside Exchange.
I am building a web application that will also allow my users to register/transfer a domain and manage email addresses through my application. However, I'm not exactly sure how to do that yet. I think there are services with APIs that will allow me to register domain names. However, working with DNS, MX records, email addresses and running an email server is something I've never done before. What do I need to know about automating this process of managing email accounts, and what sorts of solutions already exist?
for the email address part, have a look at How to communicate with a mail server through a web application
the dns part is pretty much the same, but you need a dns authoritative server with a database backend, such as powerdns (database configuration docs)
if you don't want to run the dns servers yourself, powerdns also offers hosting with API access
