ActiveSync does not sync past emails

If you connect your mobile device using ActiveSync, only current appointments and emails will by synchronised. This is a function of the design and concept of ActiveSync and is not related to our services. Normally, past emails are only synced by ActiveSync for a few days.

With mailbox, you can currently sync your emails from the last 18 months.

In addition, we have determined that the service does not always interact properly with some mobile devices and versions. If you would like to sync past emails, enter a time period of up to 1 month in your mobile device. Longer periods of time can cause problems in some mobile devices.

Use the CardDAV, CalDAV, and IMAP protocols to sync all of your data.
