Duplication of all messages sent from the iPad Mail App with Hotmail
Since deleting and then re-adding my Hotmail Account on the Mail App on my iPad Pro (to overcome another problem this Mail App was giving me), I now get duplicate copies of any mail Sent (The recipient does, thankfully, only receives one copy of this sent email) from this App. I do not have this problem with any other Apps accessing Hotmail (e.g. the Outlook App on the iPad, or Outlook 365 on the PC). How can I fix this annoying feature in the Apple Mail App, please?
Here's some further detail:
Apple suggested settings (from https://support.apple.com/mail) for Hotmail are applied:
Incoming Mail Server:
Account Type: IMAP
Username: myname@hotmail.com
Server port: 993
Authentication: Password
SSL/TLS: Yes
Server Hostname: imap-mail.outlook.com
Outgoing Mail Server:
Account Type: SMTP
Username: myname@hotmail.com
Server port: 587
SSL/TLS: Yes
Server Hostname:
smtp-mail.outlook.com)
I am not the first to suffer this double-send problem - Many others have. I have searched for solutions
but have not found one that works, e.g.
From my iPad Mail App:
If Mail>Accounts>Steve Hotmail>Advanced> Sent is set to ‘On Server, Sent Folder’ -
My iPad Mail 'Sent' folder shows any single ‘Send’ of an email from iPad Mail-Hotmail incorrectly as TWO sends. This is reflected in the Hotmail server and all other PCs across my Hotmail account, 2 copies – The recipient does, thankfully, only receives one copy of this sent email. (All other Sent emails are correctly shown in the Mail App's Sent folder with this configuration.). Not good!
If Mail>Accounts>Steve Hotmail>Advanced> Sent is set to ‘on my iPad, Sent Folder’ -
My iPad Mail Sent folder correctly shows each new single ‘Send’ of an email from iPad Mail-Hotmail BUT incorrectly the iPad Mail Hotmail Sent folder ONLY shows this sent-from-iPad email (i.e. no
other Sent Hotmail emails previously sent (and still on the Hotmail server's Sent folder) NOR any new Sent Hotmail emails sent from other devices). No previous emails sent via other devices are available in the iPad Mail App Hotmail Sent folder with this setting. Not good!
On all other devices (e.g. PCs running Microsoft Outlook), and on the Outlook App on my iPad:
Send for Hotmail works correctly, still: i.e. a single send appears on all other devices as a single ‘send’ and all previously sent Hotmail emails are correctly available under the Hotmail ‘Sent’ folder.
How do I stop this 'double send' from my iPad's Mail App + Hotmail, please?
