Thank you richbuff and FLOOD for the replies, I will do the above when I get some time and let you know how I go. Regards.

I have an issue which I am unable to solve. When I have KTS active and start Thunderbird it generates multiple popstate-1(and 2, 3 4 etc).dat and msgFilterRules-1(2, 3,4 etc).dat folders. It will often download messages multiple times. I also cannot send emails when KTS is active When I turn off protection I do not get the problems. Any advice on how to prevent this would be greatly appreciated. Details KTS version 20.0.14.1085 € Thunderbird 60.9.1 (32-bit) OS Name Microsoft Windows 10 Pro Version 10.0.17763 Build 17763 System Model Surface Pro System Type x64-based PC Regards Mark
