Outlook 2010 setup - 554 5.7.1 error

Hello Experts,

I am setting up a client's outlook 2010 and when I perform a test in outlook 2010 I get the error, "Send test e-mail message: The server responded: 554 5.7.1 <email address>

Actually were the <email address> is it is only part of the email address.

I have look at another workstation that works and reviewed all the options.

What does this error mean and what am I missing on the setup?

Assuming you have email address and POP/SMTP addresses correct (triple check these), then look for the following in the Advanced Setup:

1. Authentication when sending. This usually needs to be set now.
2. Ports 995 SSL and 587 SSL for IN / SEND are common now instead of 110 and 25 unsecured.

Either of the above not set can cause the error you got.

yep tried all of those settings... going to a different computer and trying them.  Also, I am using IMAP so it is 143 not 110.....

There is nothing else in Outlook in addition to my changes above that affect send / receive.

Look in the IMAP web settings, look in your firewall / antivirus for blocking Outlook, and then do an Office / Outlook repair (Control Panel, Programs and Features, click on Office and do a Full Repair). Then update Office (new updates in the last 10 days).

It must be something with the server.  I have this account on another computer that has an account working, same issue. Then I just setup two accounts on different computers with Outlook 2013 and those accounts worked.  I then tried this one user's account and again got the error....  would you think it was setting on the account on the server / host side?
JohnBusiness Consultant (Owner)Commented:
Yes, it appears to be an issue with the host side. Have you asked / can you ask your IMAP ISP if they can look into the issue?

The problem was on the email host side.  I emailed tech support and they confirmed they had to change some setting.   I will award points to the suggestions that help lead me to this answer.
