Older Exchange calendar disappear in Android Calendar, but not in Apple Calendar

• Open system settings


• Goto Users and accounts


• Click on the exchange account


• Click on Account settings


• Click on the settings button next to the account name

Now you see all settings for this account.

• Scroll down


• Click on "past items synchronisation"


• Change this to all past items


• Click the back button till you're out of the settings

NB: I translated "past items synchronisation", so the actual English name for this might be different, but I think it's clear what I mean. If you have the correct naming, then please comment here.
