From time to time I see an “Invalid or non-existent document” error when sending an email. To workaround I have to save as draft and restart the client, not just exit and reopen mail database.
I work from a local replica with mail addressing set to “local then server”.
I am unsure as to which index is causing this problem. I thought it was related to name resolution but it still occurs even with fully qualified email addresses.
Any pointers would be appreciated.
