Hello all, I hope everyone is doing great.

One of my clients has a company and their staff are using about 10-11 email accounts from their domain. They haven't been able to send emails to "@hotmail.com" or "@outlook.com" adresses for a few months.

I have filled some forms from Microsoft's website but nothing changed. What should I do?

 

From the error code, Mircrosoft tells me this :

 

Mail rejected by Outlook.com for policy reasons. Reasons for rejection may be related to content with spam-like characteristics or IP/domain reputation. If you are not an email/network admin please contact your Email/Internet Service Provider for help.

 

 

Here is the error message that they get :

I appreciate any help for this problem, thank you.

"spam-like characteristics". What is the content of your emails?

[jasonalien]

They are just communicating with their customers and each other with those emails. They are not spamming anyone. They don't need it.

"Please contact your Internet service provider since part of their network is on our block list." Looks like this is your next step.

Maybe someone did use your domain for spamming purposes.

You should check the blocking date so you could track it down.

 

It's not likely for them to block you with no good reason.
