Helping people with computers... one answer at a time.
The problem here is that many ISPs specifically block email transmission to anything other than their own email servers.
Hi, Leo. Outlook can receive email, but cannot send email with my Verizon MiFi Wi-Fi. I've been in contact with Verizon and my internet provider Charter with no clear answer. What can be done to change Outlook to be compatible without having to change protocols in each location?
In this excerpt from Answercast #59, I look at how SMTP settings can affect the ability to send email through various servers.
So, unfortunately, you haven't provided the error message that you're getting from Outlook when it's attempting to send. That would be very helpful to know.
When Outlook tries to send and it fails, it's usually going to tell you something about the reason. The error message that comes back, while it might look fairly technical and complex to you, actually contains valuable information for people like me.
Now, I'm going to make a couple of guesses here. When you say "change protocols in each location," I assume you mean "when you are" and "when you are not" using the MiFi.
Location #1 might be your home or you are connected directly to Charter.
And location #2 might be when you're out on the road, connecting using your MiFi through Verizon's wireless network.
Unfortunately, I have to send you back to both of these ISPs.
The problem here is that many ISPs specifically block email transmission to anything other than their own email servers. So what that means is:
When you're connected to Verizon, I'll bet using a Verizon email server would work.
When you're connected to Charter directly, I'm sure that connecting to Charter directly would work.
I'm actually kind of surprised in the Verizon case because I use Verizon. I use email protocols that everybody else uses and that go to my own servers. They're definitely not going through Verizon's servers.
So the only thing I can really suggest is to double and triple check the configuration of your outgoing email server. Try and avoid using Port 25.
Check with Charter and see if they have an SMTP option that uses a port other than Port 25. A secure port would be even better (Port 465 or Port 587, I think it is) but in any case, something other than 25.
25 is often blocked because of spammers. It's the way that spammers often send email. But if you can "authenticate" with Charter (in other words, you have a Charter account and password), then they will often provide email sending capabilities using a different port, a port other than Port 25.
If you can find that information from Charter, then configure your Outlook to send using Charter's servers through this other port, I really don't understand why it wouldn't work through both Charter and Verizon, regardless of how you were connected at the time.
Unfortunately, to give you more, I'd need to know more and that would
