To sync with an Exchange-server please add the Exchange-account to your system settings. Therefore please open the Android system settings → Accounts and sync → Add account → Microsoft Exchange/Active Sync and type in your log-in data and proceed. Please make sure, that the sync of calendars is activated.
Alternatively you can sync the data locally:
If you want to sync with Outlook over an USB-cable/WLAN/Bluetooth, you will need a sync-software like the one that comes with your device or an external one like for example "MyPhoneExplorer".
Please make also sure, that your phone is not on battery saving mode. In some cases, you will also need to check the Outlook App and make sure that the calendar sync is also activated in the count settings there. Otherwise Outlook may back the sync on the device. Finally, keep also in mind that Outlook Sync is limited. Outlook allows a maximum of 10 phones (devices) to sync between.Please remember, that BC doesn't have its own sync abilities and uses only those provided by Android. Therefore it cannot be responsible for any sync issues you may have on the device. If you have general problems with the sync on your device, please refer to this help article.
