Your EPF account will remain idle for the period during which you and the employer are not contributing towards your EPF account. As per the act, this period will be treated as a non-contributory period.
Yes, the same account may be activated after two years if you start contributing to your existing account.
Moreover, in principle, an employee shall be covered from day one of his employment; there is no question of probation or regularity, etc., under the EPF & MP Act - 1952.
Surprisingly, your company has a two-year probation period, which is neither in practice nor feasible or ethical, but rather a malpractice. Even if you are in probation, your employer is under obligation to enroll you as a member of EPF; otherwise, it will be a violation of the Act.
If your employer covers you as a member of EPF, then only can you transfer your previous accumulation of PF account given by your last employer (fill Form 13 and process it through your existing employer).
The last option available is to withdraw the accumulation of your PF by filling Form 10C (for Pension Fund if the previous contribution is less than 10 years) and Form 19 (For PF Accumulations).
Hope this clarifies your doubts.
