Solved Welcome Email Problems from 3cx.co.uk FQDN Systems

[CPMM]

I have received a few reports today from customers that they do not receive Welcome emails when clicking to send on their systems.

On investigating, I think that this just occurs on systems that have a 3cx.co.uk FQDN. If the FQDN is 3cx.uk, there is not a problem.

On further investigation, this does not seem to occur when sending to GMail email addresses, but does occur when sending to MS365 email addresses.

Therefore, I am thinking that there is currently a widespread issue in trying to send welcome emails to MS365 email addresses from systems with a 3cx.co.uk FQDN.

Is anyone else experiencing this at the moment?

Hi @CPMM are these systems running the last version 18.0.8.939?

Could you please check within the parameters the following MAILTEMPLATE_EXTWELCOME_CUSTOM

If it exists, please delete it and test it one more time using the pbx in the last version.

Thank you, Alejandro.

All systems had a custom welcome email. On deleting the MAILTEMPLATE_EXTWELCOME_CUSTOM, this resolved the problem. I guess that there is something that MS365 did not like in our custom welcome emails.

Thanks very much for pointing me in the right direction. We can now adjust these.

Much appreciated.
