Have them fail to take Egypt in 1517? If Egypt can some how stay separate and remain a thorn in the Ottoman's side, Europe might have it easier.
That's a mixed bag. Egypt contributed tribute and grain, but most of its resources remained at home. On the other hand, the absorption of the Mameluke Sultanate converted the empire into a traditional Islamic state and gave it a broader orientation, whereas before its energies were directed into Europe.
A surviving Mameluke state would also stabilize the east by acting as a balance, possibly avoiding the massive slugfest between the Ottomans and Safavids.
In other words, "I don't know".
