Hi I recently installed 3CX 15.5.5 and I used PBX EXPRESS with Google Cloud. The thing is during the installation I received the SMTP OK email and the email "your pbx is ready" so during the installation the email connection worked properly. But now, the pbx is not sending any Welcome Email with the provisioning file. I check in Settings, Email Configuration and when I click Test it's not doing anything. I am using a custom email and configuration is fine because I received two emails during the installation. But now it's not working. Is this a bug maybe? Thank you all!
