The news will hit campaigners in Somerby, Tilton, Old Dalby, and Wymeswold, all home to reportedly well-used branches listed to downgrade to a skeleton service.
However, officials also told Leicestershire County Council branches due to shut outrig
ht could be subsidised and post offices run from library vans were an option.
This means branches in Stonesby and Barkby, listed for outright closure, could retain some service.
County councillor Simon Galton, whose division includes Tilton Post Office, attended the crunch talks with Post Office Ltd.
He said: "The whole thing has been turned on its head. The good news is it's possible for Leicestershire County Council to get financial information on the threatened branches by signing a non-disclosure agreement with Post Office Ltd, which would allow us to make a proper decision.
"The bad news is there is nothing that can be done to actually stop the timetable in terms of the closures, and the one category of post offices they will absolutely not consider for subsidy are the ones proposed for outreach, including Somerby, Old Dalby, Tilton and Wymeswold. They've taken the view that what they are proposing is satisfactory for each community and that's that."
He added the only way outreach-planned branches could be reinstated would be if a case could later be put together proving the skeleton service was inefficient for local demand.
Leicestershire County Council is now expected to sign the non-disclosure form with Post Office Ltd and examine the case for providing some services in the branches listed for closure outright.
Nearly all of the threatened local branches are due to close or downgrade at the end of the month.
The news came after a Conservative Party attempt to halt the national wave of post office cuts was also narrowly defeated in Parliament.
But the Government was left embarrassed after 19 Labour MPs voted for the Conservative plan in a show of support for their threatened constituency branches.
Nationally 2,500 branches are set to shut or switch to outreach.
