I do have XP SP2 on my network but rarely even powered up. What I find 
difficult to understand is your use of the word "deprecate" in the 
context of MS and SHA1. In my experience, SHA1 has pretty much not be 
used for quite a while in favor of SHA2 (SHA-256). Thuderbird (an old 
version?) is on the XP machine, not being used, would update, data on it 
has been irrelevant for a long time. Let me know what you want are 
looking for.

I read into this and other communications that TB is in someway going to 
incorporate security certificates???
