Hi @holmesrp

 

I would recommend checking out this article: Cannot Send Email Rejected by the Server/Banned from using SMTP 

 

I believe this error is associated to an Outlook mail client. We found this Microsoft Community in which you can refer to as well: https://answers.microsoft.com/en-us/msoffice/forum/all/sending-reported-error0x800ccc78/2d9d5a04-1a7...

 

If the issue persists, you may email our PostMaster at postmaster@tpg.com.au
