As I was examining the limitation of Outlook 2010's conversation view that strictly groups by subject line, I thought, since I cannot change the mechanism, could I change the subject line of received emails so I could manually split things into multiple conversations as the occasion warrants?
My experiment began thusly:
- Open mail item.
- Edit subject line.
Select Save -- result:
"Your changes cannot be saved because you don't have permission to modify some or all of the items in this folder. Do you want to save a copy of this item in the default folder for the item?"
Answer "Yes" -- result:
Microsoft Outlook has encountered a problem and needs to close.
This error is 100% reproducible. Is there a workaround for this error? And where the heck is the "default folder for the item" ?
