I have had FusionPBX for quite some years and never had an issue until recently. Emails fail constantly on my server I use O365 and I have clients that will not get VM to email or Fax confirmations most of the time I would say about 80% of the emails fail so I have to go into the server every 30 min or so to resend them and they might fail 5+ times before they actually resend. Does anyone know what is going on or where i can check to troubleshoot this issue. I have check the send limits of 365 and I am no where close to them so I am not sure what to do.
