stock ICS ROMs don't get me exchange calendar

---

For the very first time I tried a stock ICS ROM, it showed exchange calendar
but since the next one no ROM gets exchange calendar while exchange contacts work well on every ROM.

Since the second ROM I flashed , once I somehow managed to get it right struggling with calendar app but I don't know how I exactly did that and still the problem was that it had not recognized the calendar after initial addition of an account.

The server is not the problem because Sense4 ICS ROMs and GiB ROMs have no problem getting exchange calendars.
Any idea about this problem?
