Those of you in the Mohave Valley area who have Frontier communications (Frontiernet.net) as your email provider need to be aware of some recent issues with Frontiers email service. First, if you were not aware of this, you are being required to change your account settings for your outgoing email. Frontier sent a vague email "explaining" this, but it was so poorly written many I know, including myself, had no idea if it pertained to us, what accounts it affected and what to do about it.
When Frontier switched to the new requirements this past Friday most computers would provide an error message stating that the mail could not be sent. But not all computers displayed this message!!! My office laptop did display this message, but my home PC did not!! I have no idea where my sent emails went on Friday, but, THEY DID NOT GET DELIVERED!. So, if you're a Frontier customer and sent emails out since Friday morning you may have to RESEND them.
And what happens to those non-Frontier email accounts? I have a company email service which is forwarded to Frontiernet. While I get messages, I cannot send replies using my company email account. It seems Frontier DID NOT take into account that some of us use multiple email services. My outgoing company email cannot be configured (at this time) to send outgoing mail including responses to those emails received.
We had the same issue.
Your brokerage should have been given a username and password from Frontier when they opened the account.
In Outlook or your email client, go to Tools, Email Accounts, select the email account, then select change. Go to More Settings, Select Outgoing Server, Check "My outgoing server requires SMTP Authentication, check the box Username. Enter the Username and password given to the broker when the account was opened and you should be good to go.
