Hi @brooksys 


Thanks for raising this to our attention.

Every time that you are not able to send an email, did you test it with your own email address if it's going to work? Are you unable to send out an email to a certain address or all email address are affected? Have you tried to use a different browser to open TPG Post Office? Have you tried to clear the cache or browsing history of your browser?


Sorry for a number of questions as we need to analyze this further. Please send the affected email address via PM.

there is no particular email address, it is every email I am trying to send to many different individual addresses. I can send to myself. I have tried different browsers and it makes no difference
