Sending email problem

[thehurricane]

Hello,

I have huge problem with my PS shop. I have configured SMTP (Office365) on my PS 1.7.6.1 shop and the problem is that sometimes mail is not sending. It happens sometimes 1 of 30, but sometimes 5 of 10. It happens on every email template, sometimes on registration, order and even test email. On test email I have an error:

"Connection could not be established with host smtp.office365.com [Connection timed out #110]".

 

Does anyone had problem with something similar?

As per our understanding, Its not the Prestshop issue. 

"Connection could not be established" that means either its due to connection office365 is blocked by your server (most probability) OR office365 blocked your connection.

Have you tried other SMTP service as well. If same issue is being faced with other SMTP services like gmail etc then its the hosting issue.

Kindly check the same with your hosting as well.
