Hi, hoping for some advice from some tech savvy people......
Last week I sent an email to someone. It's showing in my sent items and I know they've definitely read it (they took action as a result).
Sent the same person another email yesterday and i got a notification that it was undeliverable. Clicked on 'send again'.
It's still not showing in my sent items folder so it looks like it will be undeliverable again (think it took about 24hrs for me to be notified last time).
I've sent test emails to other friends and they have received and the email is showing in my sent items.
Not sure if it makes a difference but it's a 'live.com' email address I've got and sending to someone with a gmail account (in case that makes a difference with what "undeliverable" means!
TIA
