Hope you can help me with the issue we are having on exchange 2013.
"A storage transient failure has occurred during content conversion" when checking the exchange queue i always see an email stuck from a certain user, sending email to a gmail account. I have tried sending test emails to gmail accounts with different email formats and it is going out without a problem. I couldn't seem to recreate the problem on my end. The workaround i have been using were enabling, disabling and putting it back TNEF to default. Does anyone have a permanent fix for this.
