May be related to Outlook on my Apple phone. I have my email on PC, Microsoft Surface and IPhone. All are synched.
Does the problem only occur on Apple phones?
What is your account type? (Exchange/IMAP/POP)
According to your description, there are a few possible reasons why this might happen, and some solutions you can try to fix it.
One reason that email messages that you send do not appear in the Sent folder is that Save copies of messages in the Sent Items folder is not enabled. To check this setting, go to: File > Options > Mail> Save copies of messages in the Sent Items folder.
The second reason is that emails are blocked or filtered. Please try contacting the recipient to mark your email as safe or trusted.
The third reason why an email you sent doesn't appear in the Sent folder is stuck in the Outbox (due to connectivity issues or sign-in issues). To fix this, you can try these steps:
- Make sure your internet connection is working and you are logged in to your second email account.
- Click Send/Receive > Update Folder.
- If you see any messages in the Outbox folder, double-click them, and click Send.
