Received duplicate emails to Outlook.com account.

Original Title: duplicate emails received for outlook account

Hi,

I've been receiving duplicate emails recently. I have 2 alias account and 1 main account. Both alias account allows both sending and receiving of email.

I thought it was due to the alias that i'm receiving duplicate email, but like i said, i have 3 email in total but i only received 2 email (including the duplicate one).

I searched online for help, but of course none had helped me with it. I've saw one article which said to make one of the account as send only. However, as all 3 emails have different usage purpose, i hope to receive all the email in 1 account. And also, like i said, instead of receiving 3 emails in total, i only received 2.

I'm really troubled by it. Any help would be appreciated. Thanks !
