Hi,
We use Exchange 2010 Mailserver and MS Outlook 2010/2013 mail clients. I'm quite confused about configuring junk mail filtering, so can somebody give me few simple answers.
If i'm not wrong basically it goes like that:
Filtering can be made on server/mailbox level, when it can be configured using Exchange powershell. The other way is MS Outlook Junk filtering and it can be configured using GPO.
My first question is, are those two ways completely separated or not? I have found articles which are conflicting in my opinion. For example this speaks how to configure Outlook junk filtering using powershell which should not be possible. Or does Outlook mean OWA in this example? http://beccabits.com/2011/10/07/how-to-bulk-modify-safe-senders-list-in-outlook-with-exchange-management-shell/
Second question is if i configure MS Outlook Safe Senders list i can see changes using Exchange powershell which means that mailbox junk filtering can be configured through MS Outlook. Is this correct?
Third question concerns MS Outlook safe senders list which i try to load from txt-file using GPO. Problem is that it works only some users. Checked the situation using process monitor and looks like Outlook reads only junkmailimportlists reqkey and not the other keys, for example junkmailsafesendersfile. Reqkeys have been loaded from GPO correct anyway. I have tried to fix this and sometimes the only way looks to be updating junkmail settings through OWA and sometimes update-safelist from powershell. I have tried to update all users safelist using powershell but it doesn't work. How to fix this? We have thousands of users and fixing one by one is not the solution
Thanks in advance
Tried a little more now. Looks like only updating Junk mail list trough OWA helps the situation, when Outlook SafeSenders list do not update using GPO. After using OWA, Outlook GPO works.
Using OWA is not the solution as i said before but is it possible to do the same thing by for example adding some address to every users mailbox safe senders list using powershell? That updates users safelist like OWA do or am i wrong?
