JoshRowe4905 Posted May 26, 2014 Share Posted May 26, 2014 We are using office365 and we are trying to setup the mail setting in the general section and when we send a email out we get a error saying "Email Sending Failed - SMTP Error: Could not authenticate." we have checked all settings user names and passwords and nothing seems to work. I have seen a couple people post with no resolve to the problem. Any help would be great! 0 Quote Link to comment Share on other sites More sharing options...
WHMCS Support Manager WHMCS John Posted May 27, 2014 WHMCS Support Manager Share Posted May 27, 2014 Hi, To see the communication occurring between your mail server and WHMCS, please add the following line to your WHMCS configuration.php file and then try sending an email to a customer from the client summary page and you will get output on screen a log from the mail server. smtp_debug = true; If you're unsure how to interpret the output, paste it here for us to review. 0 Quote Link to comment Share on other sites More sharing options...
mysmallbizu Posted December 5, 2014 Share Posted December 5, 2014 (edited) Office365 and cron pop support tickets. I've got my WHMCS install sending email through office 365 with no issues (only works when mail type is php (Mail) in settings mail type) ... but it's getting the support department pop settings to authenticate that won't work. Sending and Receiving email runs fine in any email client using office365 but with WHMCS I get this error from the cron job when WHMCS tries to pop office365.com. <b>POP Import Log</b><br>Date: 05/12/2014 06:20:01<hr>Host: outlook.office365.com<br>Email: support@wpblogsupport.com<br>An Error Occurred: Can't connect to outlook-namsouth.office365.com,995: Connection timed out the email address and password are correct and work in any other pop email client to send and receive email.. as well as for sending email from WHMCS via office365. It's just the support department POP settings that arent' working the current settings for external office365 apps connecting to office365.com are [TABLE=class: banded] [TR] [TD]POP3 [/TD] [TD]outlook.office365.com [/TD] [TD]995 [/TD] [TD]SSL [/TD] [/TR] [TR] [TD]IMAP4 [/TD] [TD]outlook.office365.com [/TD] [TD]993 [/TD] [TD]SSL [/TD] [/TR] [TR] [TD]SMTP [/TD] [TD]smtp.office365.com [/TD] [TD]587 [/TD] [TD]TLS [/TD] [/TR] [/TABLE] Any suggestions?

mysmallbizu Posted December 12, 2014 Share Posted December 12, 2014 Quick update.. is was the firewall on my server not allowing outgoing pop connections from the cron. Opened it up and office365 works perfectly now.. 0 Quote Link to comment Share on other sites More sharing options...
