    I am back again with problem, which i didn't have for a long time.

    We are running email marketing campaigns locally for our clients and we do send a lot of emails, but in a few years time we didn't have this like bounce from Microsoft:

    I've tried to find solution but still no luck. Any advice?

    Hi stefan,

    First please verify you are not spamming etc. Even if your campaigns are not spamming there could be a problem with a web form that being used to spam etc. You can check this easy enough by skimming your outgoing mail logs for problems. Also, here are our Top 10 Email Marketing Tips

    Once that is done see this link - Hotmail Blacklist
