Why does the calendar delete old entries?

[WPCentral Question]

My windows Nokia lumina 520 calendar deletes old calendar entries. When I look back a couple of months it's all blank, even recurring items like birthdays. How do I stop this?

[h=4]Syncing Microsoft accounts and Microsoft Exchange accounts[/h] To see the calendar for a Microsoft account or a Microsoft Exchange account (typically used at work) on your phone, just set up the account. The calendars will automatically show up along with your contacts and email, and your phone will sync the following events (these settings can't be changed):

• Two weeks of past single-instance (non-recurring) events.

Yes, I've noticed this happening to. They seem to be visible if I look at them online, but not on my phone. I now have to look at email reminders to remember certain events when I'm out.

Has anyone been able to shed anymore light on this issue as it's still occurring on my account.
