Hi,

We do have a GPO that currently imports a safe sender list into User's junk folder in Outlook. This GPO has been in place for a while, but suddenly the safe sender list are not added to user's email.

safe sender txt file corrupt or file format ?


User Configuration > Adminitrative Templates > Microsoft Office Outlook 2016/Tools | Options.../Preferences/Junk E-mail

Add e-mail recipients to users' Safe Senders Lists : Enabled

Trigger to apply junk email list settings : Enabled

Trust e-mail from contacts : Enabled

Specify path to Safe Senders list (Enabled)
Specify full path and filename...... \\domain\dfs\somewhere\safesenders.list


Any ideas why outlook is not importing the safe sender list?
