Mobile App Android: Addressbook integration

As I use emClient on the desktop I’ve switched from another Android Mail App (Nine) as well on my Android Mobile.
Addresses /Contacts are synced to the Phone (Exchange/CardDav), but they do not seem to be available to other Android Apps like WhatsApp.
Do I miss a setting?

If your Exchange / CardDAV contacts are not available in What’s app and are already synced to your mobile phone", “then you haven’t allowed permission to your phone contacts in What’s app” as is not enabled by default in What’s app.

You can Google how to do that or go to the What’s app website for documentation.

If your Exchange / CardDAV contacts are not available in your eM Client mobile app, then I would use the QR Export code option from eM Client for desktop to add them automatically.

https://www.emclient.com/webdocumentation/en/10.0/emclient/default.htm#QR%20Export/QR%20Export.htm.

To export on the desktop via QR Code, go to “Menu / Tools / QR Export” & follow the prompts.

Or on the desktop, go to “Menu / Settings (Preferences)” and “click the QR Export button in the toolbar” of the Settings window will give you the options to export.

Select all the Settings, Accounts & any other options you want on the QR Export screen. Then click “Export”, and when the QR Code appears “open the eM Client mobile app” and choose the option to scan the QR Code as per the QR Code instructions

Thanks for your explications @cyberzork
I checked WhatsApp permissions - it has access to contacts. Furthermore with my former email client it worked as well.
I’ve installed the accounts on my phone exactly as you described using the QR code.
As the contacts aren’t available in any app than emClient (not in phone etc).
I think, that the emClient contacts are not availabe as Android address book - aren’t they?

If your Desktop contacts in eM Client are not in your Android phone address book contacts, then you will need to either export them from your Mail account contacts in eM Client or Local contacts in eM Client to a vCard (.vcf) file, and then import / add them to your Android phone address book contacts.

You can export Desktop mail account contacts or Local contacts in eM Client contacts via “Menu / File / Export” in whatever format you need. Then copy that to your mobile phone and import the contacts.
