FYI Outlook 2016 0x800CCC78
For the past few days when I was sending e-mail I was getting the error 0x800CCC78 with the message something along the lines of server returned 454.4.1.0 requested action aborted. I tested sending e-mail with Windows Mail and had no problem so I figure the problem must be with Outlook 2016. Looking up that error code on the Internet provided several suggestions and the suggestion that worked for me was using MicrosoftEasyFix 20101 to repair my PST file. Once I repaired the PST file I was able to send e-mail again.
I wonder what caused this corruption of my PST data file after many years of no such problem? Does anyone know if there is a size limit on the PST data file? I am guessing that is the cause of my problem. I have now reduced the size of my PST data file by 80% by allowing Outlook to archive my old messages. I will miss being able to easily search all my e-mail.
