What permissions are required in Microsoft Öffentliche Ordner (Public Folders) to enable two‑way contact sync with Android via sync.blue®?

Grant access via an Azure app registration in Exchange Online with the EWS application permission full_access_as_app (admin consent), ensure the Public Folder is of type Contacts, and assign the app/user permissions to create, edit, and delete items on that folder (e.g., Editor or Publishing Editor) so sync.blue® can perform two‑way contact updates with Android.

How are Android devices connected to sync.blue® to show Public Folder contacts without installing extra apps (CardDAV or LDAP)?

Android devices are not paired directly; instead, a sync.blue® connection is created from Microsoft 365 Exchange Online (Public contacts) to Google Contacts, and the phone’s existing Google account sync then populates those Public Folder contacts into the native Contacts app automatically—no CardDAV or LDAP apps required.

How often can synchronization run, and can one‑way or two‑way schedules be configured per Öffentliche Ordner or connection?

Synchronization can be scheduled per connection to run manually, hourly, daily, weekly, or monthly, and the direction (one‑way or two‑way) is selected per connection; therefore, if different Microsoft Öffentliche Ordner need distinct timings or directions for Android contact sync, create a separate sync.blue® connection for each folder.

Which contact fields and types are synced (people, companies, custom fields), and how does sync.blue® avoid duplicates when updating existing contacts?

sync.blue® syncs both people and company contacts between Microsoft 365 Exchange Public Folders and Android; for people it transfers first name, last name, company, department, position, birthday, phone numbers (business, private, mobile, other), business email, and full addresses by type (business/private with street, house number, ZIP, city, state, country); for companies it transfers company name, email, annual turnover plus the same phone and address fields; support for additional/custom fields varies by connected apps and field mapping is best‑effort and not user‑configurable; to avoid duplicates, existing contacts are matched by email or by the combination of first and last name, then fields are merged/updated with source values taking priority when conflicts occur.

Where is data processed and stored, and what encryption and GDPR controls does sync.blue® provide for Android–Microsoft Öffentliche Ordner sync?

For the Android–Microsoft Öffentliche Ordner sync, data is processed and stored on the sync.blue® cloud in Germany at partner data centers operated by Hetzner (Nuremberg/Falkenstein) and NETWAYS (Nuremberg), per the help center; by default contacts are not persistently stored and are synchronized live, with optional storage only if features such as Address Book/Directory are explicitly enabled; GDPR controls include a downloadable Data Processing Agreement and documented technical and organizational measures; encryption specifics are described in the sync.blue® help center.
