The problem below is not related to our servers but it has been causing some frustrations for some clients so we thought we would document it.
We have noticed an increase in tickets from clients who say their email has suddenly stopped sending - about 8 tickets in the past few days. The common factor is that email has worked for months, even years and now it has stopped sending emails. Email is still being received though.
The common factor seems to be Outlook and MS Operating System.
A ticket came in from a local Church just a few minutes drive from our office. We just went over there to see what the problem was and for some reason the tick box to enable ‘SMTP Authentication’ was unticked.
We are unsure why this appears to be happening but it does appear some Microsoft Update is ‘unticking’ this box in outlook settings.
In the case of the local Church we simply edited the mail settings and ticked the box to enable ‘SMTP Authentication’ so that the software uses the user name and password to send emails again. This solved the problem right away.
If you use Outlook on a Microsoft Operating System and suddenly discover your email is no longer sending please check this settings before contacting us.
Thanks
