To anyone who has recognized this question it is because I lost an earlier answer.
1. The Data File I believe is the last one working was : *** Email address is removed for privacy ***(5)
2. Under "Mail Setup - Outlook", "Data Files", there are:
A. UNCHECKED Name: "*** Email address is removed for privacy *** Location: C;\Users\george\AppData\Local\Microsoft\Outlook\george.delmonte.com.pst"
B. CHECKED Name: C:\Users\george\Documents\Outlook Files\Outlook.pst
3. Under "Mail Setup - Outlook", "E-Mail" CHECKED Name: *** Email address is removed for privacy *** Type: IMAP/SMTP (send from this account by default)
4. I guess the identified Data File [(1.) Above] is the last one working because, after it was given a new extension by a virus finder, Outlook would not Send.
5. If I REMOVE the existing CHECKED Data File (2.B. Above) and Open File Location (where the Data File in 1. ABOVE) and select the Data File in 1. Above, will that restore Outlook to correct working order? If not, then WHAT should I do?
Please keep it simple. I'm an old guy and my mind's not as complicated as younger minds.
