Improvement possible? E-Mail with non-ASCII To: addresses stuck in Outlook Outbox Folder without error.
-
When you send an email to (for example) müller@domain.com, which is not a valid email address (non-ASCII is not allowed before the @), the following happens:
- Outlook 2019 with Hosted Exchange (Office365) account: mail is sent, but you get an email back that this is was not valid and you need to fix your destination
- Outlook 2019 with IMAP: mail is stuck in outbox, but you get at least sometimes an IMAP sync error that shows an error message which helps you diagnose what is wrong.
- Outlook 2019 with Z-Push Activesync: no error message at all, mail is just silently stuck in the Outbox folder.
This is especially irritating if you send something to 40 recipients: Mail is then just stuck in the Outbox and nothing happens. So 40 recipients don’t get the important mail because one single address has syntax problems. And you have no clue why, because finding the one email which has incorrect syntax in the To: address among the 40 recipients is really hard to do.
A better behavior would be like Microsoft’s Hosted Exchange: accept the defective email but send a error message back. I assume this would be possible, because for example mail with an From: to which the account does not have send-as rights to is also accepted but you then get an error back. Any chance this could be improved? This really has been one of my main problems over the years with the Outlook-via-Z-Push implementation, and it would be awesome if this could be fixed/improved.
