What to do if you suddenly can’t send email from Outlook anymore
The two things most likely to leave you saying, “I cannot send emails from Outlook anymore” are:
- Your email provider has changed settings to enhance security.
- You’re working on this in a different location, one that isn’t directly connected to your email provider’s network.
Let’s touch on the second possibility first. Some email providers won’t let you send email unless you connect directly to their network. Your computer must either plug into their router or connect to it by WiFi. In those situations everything works great.
But try to connect from somewhere else and you can’t reach their outgoing (SMTP) mail servers. The result: you can receive mail fine, but you can’t send email. If this describes your situation, please click over to Can’t Send Email In Certain Locations, where I’ll show you how to deal with this.
I can’t send emails from Outlook anymore even though my computer is connected to the right network.
You can thank the scammers and crooks for this. They use other people’s email systems to flood you with ads for sex aid, herbal weight loss scams, and all sorts of nasty malware. T0 prevent the cretins from abusing their networks, services are increasing security.
It’s definitely the right thing to do as it slows the junk mail plague, but the changes they have to make to do this sometimes need to be reflected in your Outlook 2010 configuration. If they aren’t, you find yourself saying, “All of a sudden I can’t send email from Outlook!”
Here’s what I recommend. First, try sending again, just in case there was some sort of temporary glitch that’s healed itself. If that doesn’t work, and you still cannot send email from Outlook, I suggest you go to the Living With Outlook 2010 Email Accounts home page and see if I have posted instructions for your email service there. I do my best to ensure that the instructions you find there are up to date, so if there has been a change in settings for your email provider, I probably have it documented here.
If you find your service, walk through the instructions and see if they differ from the settings you are using now. If so, updating your Outlook 2010 settings could be all it takes to fix the problem.
If that doesn’t work, or you can’t find your email provider listed, try going to the tech support page on their website and see if they have posted new instructions. And if this happens, please post a message below so I can be sure to keep this site up to date. Thanks!
I tried all this but I still can’t send emails from Outlook 2010!
Hopefully you will never get to this section, because it means none of the advice above helped and you still can’t send email. But if you do get here, there’s one last thing you can try. If you can’t send mail using the advice above, you can try using someone else’s SMTP server to send it.
Unfortunately, the same problems that have caused email providers to clamp down on security have reduced the number of available SMTP servers that aren’t part of someone’s email service. One solid company that’s still providing an independent SMTP service is SMTP2GO.
These guys provide a very affordable service, and even offer a free trial, so you can see if their solution will work for you before making any commitments. That’s what I did when my Android phone couldn’t send email. It took about 10 minutes to fix the problem (the instructions are simple to follow), and it has worked perfectly ever since, thanks to SMTP2GO.
Outlook can’t send email? SMTP2Go is the answer, anywhere on Earth. I can recommend it without reservation because I use it myself.
