Have searched this problem for a while. If I have missed the solution, pls.excuse me.
I have recently lost the "Junk Mail toolbar" in my outlook 2007.
When I try to enable it via Tools, Trust Center, Add-ins, it gets disabled by Outlook when I click OK.
I have now removed it, with the intention of re-inserting it, via ADD and then pointing to ...mlfoshim.dll but Outlookthen kindly informs that this is not a valid add-in.
What am I doing wrong ?
