- Tap on the Sandwich menu on the upper left.
- Tap on the account name of the account you’ve used up until now (e.g. Gmail).
- Select Davx5 Address Book.
That’s it! The Android address book app will now display your Posteo contacts.

- Tap on the Sandwich menu in the upper left.
- Open Settings.
- Tap on Default account for new addresses.
- Select Davx5 Address book.
That’s it! Your Posteo address book is now the default address book on your Android smartphone.
How to create entries in the Posteo calendar
You have used a local calendar, a Gmail calendar or a calendar from another provider up until now? The Android calendar app remembers which calendar you last used to save when creating an entry.
Simply select your Posteo calendar as the destination when creating an entry in the Android calendar app. All future entries will automatically be saved at Posteo. To do so, follow these steps:
- Open the Android calendar app and click on the plus symbol to add an entry.
- Open the calendar selection underneath the title of the entry.

Tips & troubleshooting
The following tips can help identify the cause of problems on your smartphone and to solve them. Should they not help you, please contact Posteo support at firstname.lastname@example.org.
Problems when setting up or synchronising
Under certain circumstances Davx5 can not connect with the Posteo server. In such cases you will receive an error prompt when setting up or synchronising. Problems with Davx5 can be fixed by doing the following:
- Deactivate the wireless network. Verify if synchronisation can be made via your mobile internet provider.
- Deactivate anti-virus software if applicable as a test.
- Deactivate active VPN connections if applicable.
- Verify that your password has been entered in correctly.
Import your current contacts to Posteo
Address book entries of various accounts are saved separately on Android devices. Because of this, contacts that are already saved on the phone or contacts that have been synchronised with the telephone are not transferred via Davx5 to your Posteo address book.
How to import existing contacts to Posteo:
With our migration server you can import address books from many providers with a few clicks to Posteo (e.g. Gmail, web.de, Gmx, iCloud). A guide for importing address books can be found here.
Contacts that are saved locally on your telephone can be exported as a .vcf file with the help of the Android contacts app. Afterwards, you can import this file via Posteo webmail to your Posteo address book. A guide for importing can be found here.
Problems with displaying contact pictures in Davx5
It’s possible that Davx5 will not synchronise contact pictures even though these can be seen in Posteo webmail.
In this case it helps to edit the affected contact in Posteo webmail by making a small change and then saving. It’s enough, for example, to add a note or to temporarily change the email address of the contact. After saving Davx5 should update the contact picture with the next synchronisation.
