I really really really appreciate what you have done!!
And thank you for the prompt response all the time.
If you need someone to give the fix a try, please let me know.
(In case I may not visit this webpage for a while, you can find me by personal email).
Thank you for also providing a workaround before the problem is fixed. I’ve learned something from you for being considerate on this topic.
(If I really need the complete decrypted email with images embedded, I will ask my colleague who has the last Symantec license to forward the decrypted mail to me.
I believe I will not bother him frequently within those weeks.)
