Hello,
I have clearos 6 running as a windows domain controller, and also on the same box zarafa communitie is running.
In windows 7 no problem at all using outlook 2013 connecting whit zarafa plugin and pop3 to archieve mail.
I upgraded to windows 10 but now i can't recieve pop3 mail anymore. It does not seem to accept my password.
what i did.
Installed windows 10 and tuned it by removing apps ect.
Joined the windows box to the clearos 6 windows domain by using the fix whit 2 registry key's.
Reboot system and logged in whit user account.
Installed Office 2013
Configuerd the zarafa plugin and configuerd it (no problem getting it to work)
I configuerd the pop3 account but it would not connect.
the box for password pops up and if i fill in my passowrd i get.
Error : Recieving .... Error (0x800CCC92) the amilserver has rejected your signon. checke username and password. de server reaction was -ERR syntax error.(it was translated form dutch)
i have already tryed the following.
I have reinstalled the system, i have also tryed a clean install on different machine.
I have shutdown the firewall in wondows and windows defender.
no luck recieving POP3 mail.
When i loggout of the domain account and login to a local windows account i can recief pop3 mail normaly whit the same setup.
The user name and password are oke because i can login to zarafa web mail.

Hello Andrew,
I did found out you could telnet into a POP3 mail accout and tryed it, and i could get a connection whitout any problem.
That told me that the problem was not in the windows 10 firewall.
So i kept looking for a solution and luckely i found it.
Turns out it has noting to do whit clearos doamin or the zarafa server
You have to set the ProtectionPolicy in the registry to enable a local backup of the MasterKey instead of requiring a RWDC.
The only thing you need to do is find the following key using regedit
HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb
And add a new DWORD (32bit) subkey whit the following name "ProtectionPolicy" and set the value to 1.
ANd your problem is solved
Took me about 2 weeks to find out why my mail did not work, hopefully i save someone a lot of trouble whit this post :-) -

Hi Frans,
Can you successfully telnet your POP3 account when logged onto your domain profile?
https://technet.microsoft.com/en-us/library/dd789740(v=exchg.80).aspx (scroll down to "Procedure" for telnet instructions)
Alternatively, try installing and configuring a different mail client such as Thunderbird...... either method will help establish if this is an Outlook issue, or something deeper within Windows.

Hello Ben,
Thanks again for your responce.
I have looked at the log files you suggested but no error or sign of a failed login.
I have the feeling that the validation request is not leaving the windows 10 workstation at all.
Something internal is stopping the request.
Pop3 does not work at all, i have also tryed to configuere an outlook account instead of my own mailserver but i get the same error.
As soon as i join the cleasos domain something gets blocked. when i go back to a local accout on the machine POP3 is recieved like normal.
The big question is what is stopping the POP3 validation request from leaving the workstation when i join the clearos windows domain ?
I hoped some one had the same problem and found a solution.
If i find out whats wrong i will post it here, but im affraid it will take some time to find a solution. -

Hello Ben,
Thank you for your responce.
I did add the line to the config file and rebooted the server.
I did not change any thing to the fact that i can not recieve pop3 mail.
I also tryed to config a outlook account and found that it has the same problem.
I have the feeling that authenticating the pop3 password is failing some how.

Frans,
I don't think this is your issue since you don't say anything about issue logging into the domain, however, it's worth a try maybe since it is specific to Windows 10.

In addition to the "server max protocol = NT1" mod in /etc/samba/smb.conf you should also do the registry edits.
After a reboot of the work station (and a restart of Windows networking - smb and nmb services) on the server, see if that works.
