Office 365 Exchange Online server blacklisted
At 10:20AM 24 Nov AEST I'm seeing reports that Office 365 Exchange Online server mail-me1aus01hn0228.outbound.protection.outlook.com is appearing on different blacklist sources http://mxtoolbox.com...
This is where being an Exchange admin gets frustrating. On our own servers, we'd investigate, remediate and apply for the listing to be removed. With Exchange Online, Microsoft will do the same ... eventually. It just takes them longer.
On the upside I never need eseutil.
So we wait.

Microsoft confirmed the issue is resolved.
I don`t see messages send through the high risk delivery pool anymore.

Mxtoolbox.com is still reporting that Exchange Online server as being blacklisted on 6 different services.
- Ok, but the issue was all email send to Hotmail, Gmail etc was send via the High Risk Delivery Pool and that issue was solved. Yes this pool of servers is still on the blacklist, but this is not the server pool which is used to send. Have a look at this article for more information about the server pool:
