Hi,

I have Microsoft Outlook saying my IP is blocked on a 'local' database on my mac. I don't know where or why it is being blocked.

Could it be maybe saying this message because of a firewall issue? This only started this morning with no previous issue. 

This is the error:

I can't see anything that should be stopping it.

I can put the computer on a different network and it does work and I can send out. The issue is this computer needs to sit on the office network and the IP is static. 

Flushed the DNS, tried Google's DNS but obviously that's not the issue. This is happening on 1 other mac.

They are just POP accounts as well.

Any help would be appreciated.

Thank you.
