Plesk failing to create email account

[WesleyG]

This is a brand new server, which we have 17 others with the exact same setup and versions, with:
Windows Server 2008 R2
Plesk 11.5
Smartermail (local)
MailEnable is NOT installed (and verified through Plesk upgrade system)

When I try to create a domain I get the following:
Invalid class string (COM Error 800401F3)
at Can't CreateInstance(MEAOPO.PostOffice)
at (DispatchHelper::CreateInstance line 40)
at execute console command --add-domain(vconsoleapp::start line 97)
at execute "C:\Program Files (x86)\Parallels\Plesk\admin\bin\mailmng.exe" --add-domain "--domain-name=secure6.win.xxx.com" "--disk-quota=-1" "--total-disk-quota=-1"(vconsoleapp::run line 107)
Execute file name: C:\Program Files (x86)\Parallels\Plesk\admin\bin\mailmng.exe

I have verified that the domain does not exist in Smartermail

I have also verified that Smartermail is properly setup in Plesk components

Ideas???

I see other forum posts saying make sure domain doesn't exist, so not sure where to go from here.

Thanks!

All figured out. IPs were listed in Plesk, but they were not in smartermail. Add to smartermail, and good to go.
