Sent Emails appears to be missing at random.
Hi,
Sent emails appear to be missing, even though the recipient did receive. Check and confirmed the following.
>IMAP settings correct.
>Mailbox behaviors Sent Mailbox folder is set to the same on all devices linked to email account.
>Searched email dates knowing that these are ones I've sent and the recipient confirms they received, but I can not find them in any folder (Sent Messages or Sent Items).
>No Rules have been setup.
>WebMail shows the same sent emails as on each device.
Current sent folder shows a list dating oldest April 2nd to current, but have some missing from the 29th. I will confirm on May 1st if they all disappear or not. Can I update to a newer version of Mail.app like 13.0 ?
Also noted this morning when accessing Mail/Accounts it showed no active accounts. Closed reopened and now they reappear.
Mail.app Version 11.5 / macOS High Sierra Version 10.13.6 / ICSS webmail provider
