First started yesterday afternoon, after working just fine in the morning, it would not save to SENT folder. Now this morning it will also not save to DRAFTS (in tools>account settings>copies & folders>place a copy in) both of those are checked properly. PLUS, I have two email accounts in Thunderbird, and it now keeps popping up that it cannot sign into one of those accounts. It is up-to-date, I have cleared the start-up cache. Don't know what to do next to solve these issues. Thanks NM.
