Blocking some e-mails

Hi, having suddenly problems with e-mails not being received to my hotmail account, (but strange to my g-mail alternative account no problem). It is like they are blocked. Read somewhere it could be my antivirus settings, but where and how do I check this ? Having AVG Secure VPN and AVG Internet Security. Or is this related to the mail program it self ?

Hello Mia,

We're glad to look into this and help you.
To check whether your AVG Internet Security is causing this issue, please disable it temporarily and check if you're able to send/receive emails.
Refer to this article to temporarily disable your AVG Internet Security.
Also, you can disable/turn off your AVG Secure VPN and check if the issue persists.
Thanks in advance. Keep us updated.
