sending email from i phone

Hi, @monique schelvan

Sorry for this unwanted experience. It's worth looking at what sits between the Outlook app and your mailbox, like the network or the link between your phone and the account, rather than the app itself.

Here are some suggestions you can try:

Turn off Wi-Fi and send a test message over cellular, then try the reverse. Some home and public Wi-Fi networks block outgoing mail, so this shows right away if the network is at fault. Also go to iPhone Settings > Cellular and make sure the switch next to Outlook is on, otherwise the app can't send when you're off Wi-Fi.

If you have a VPN or Low Data Mode turned on, switch them off for a moment and try again, as both can quietly stop messages from leaving.

For an Outlook.com or Hotmail account, sign in at outlook.live.com on a computer, go to Settings > General > Mobile devices, select your iPhone, delete it, and save. Then restart the phone and open Outlook so it reconnects. This clears a stuck link between the phone and the mailbox that the app can't fix on its own.

In the Outlook app, tap your profile picture, then the gear, then the account, and check which type it says. It should show Outlook.com or Exchange, not IMAP. An IMAP setup can sometimes receive fine but fail to send.

If the account is new, make sure you clicked the verification link Microsoft emailed you, since unverified accounts can't send.

If you're still stuck, let us know whether you see any error message or if the mail just sits there, and whether it's an Outlook.com, Gmail, or work account.
