Extension of Researcher's contract form remaining RTN funds (MSCA IF)

Dear MSCA Alumni,

Have anyone of you had their employment contract at their host institution extended beyond the end date of the project from remaining funds in the Research, Training and Network budget? I was discussing this with my Department and have always assumed that this would be possible. Now I was very surprised to hear from my Department Manager that my contract cannot be extended beyond the end date of the project. Please share your experiences or direct me to any useful sources of information.

All best wishes
