Emails alerting techcnicians by email when a new request is created- not working

Hi,

We have set up the support desk to alert certain technicians by email when a new request is created. This has been working fine for months, but seems to have stopped working since 10/04.

All other email triggers are working as expected.

We use Office 365 to send these emails.

Is anybody else experiencing this or can help?

thanks

Gareth Parry
