Just over a week ago a problem appeared with my primary email account. I can no longer send email through that account when using Microsoft Outlook 2007, nor will it send from a brand new version of Thunderbird, on my main work computer. Nor can I send invoices through that email from a different computer that is set to send through outlook/webmail not quickbooks servers. Earlier today I tried configuring the email account on the machine from which I send invoices in Outlook 2007. Still no ability to send.
Curiously, I can receive emails from this account on any platform.
I contacted Microsoft, they could find nothing wrong and declared the issue was not with outlook. I contacted my ISP, Charter/Spectrum, they said my service was normal, and there were no issues with their service. I contacted my site hosting company (techark internet services), they even used teamviewer to look at my settings, etc. They say the issue is not with them and that my website is working properly. They had me go into my sites control panel and use webmail, and sure enough email will send there with roundcube.
And that has made me even more confused, I can send email from the account on my iPhone, my android tablet, and even a gmail account I have set up to send through that email address and a couple more. But not through my main setups for everyday work.
Have you ever encountered a problem like this? If you could offer a solution I would be very grateful.
