What sync schedules and latency can be expected for publishing GAL contact changes to IBM MaaS 360-managed devices?

sync.blue® supports scheduled GAL→IBM MaaS 360 contact syncs at hourly, daily, weekly, or monthly intervals, or manual runs, operating 24x7 (([help.sync.blue](https://help.sync.blue/hc/en-us/articles/13490897221522-At-what-intervals-are-contacts-synced))); updates are processed incrementally on the next scheduled run, so publication latency equals the chosen interval—for example, up to about 60 minutes with an hourly schedule (([help.sync.blue](https://help.sync.blue/hc/en-us/articles/10031338382610-How-can-I-initiate-a-complete-re-synchronization-of-my-contacts?utm_source=openai))); after sync.blue® writes updates, visibility on devices occurs with the next MaaS 360/device sync cycle, which is managed by IBM MaaS 360.

Is any local software needed for GAL–IBM MaaS 360 sync with sync.blue®, and what security and privacy controls are in place?

No local software is needed; sync.blue® runs in the cloud and connects Microsoft Global Address List (GAL) with IBM MaaS 360 without any on‑premise installation. Privacy controls include GDPR‑compliant processing with an available Data Processing Agreement, admin‑controlled Microsoft 365 app registration to govern GAL access, and default pass‑through syncing in which contacts are not stored by sync.blue® unless storage features (such as Address Book, CardDAV or LDAP) are explicitly enabled.

What setup steps and Microsoft 365 admin consent are required to connect the Global Address List (GAL) to IBM MaaS 360 with sync.blue®?

Set up sync.blue® by registering an app in Microsoft Entra ID, adding the Application permission User.Read.All (and OrgContact.Read.All if organization contacts should be included), granting admin consent, and creating a client secret; then in the sync.blue® dashboard create a new connection with source “Microsoft 365 – Azure Directory / Entra ID / Global Address List (GAL)”, authenticate with the app registration (Tenant ID, Client ID, Client Secret), choose IBM MaaS 360 as the destination and typically deliver contacts via CardDAV by deploying a CardDAV account through MaaS360 that points to the sync.blue® CardDAV server (Server: carddav.sync.blue/MY_API_KEY/addressbook; Username/Password: MY_API_KEY), and start the scheduled sync to keep GAL contacts updated on MaaS360-managed devices.

Does sync.blue® support one-way and two-way GAL–IBM MaaS 360 synchronization, and how are updates, conflicts, and duplicates handled?

Yes—sync.blue® supports selectable one-way and two-way GAL–IBM MaaS 360 synchronization; syncs run incrementally on a schedule, update existing contacts, and use matching by email or by first and last name to avoid duplicates; when an identical contact has differing field values, the value from the configured source is applied, while two-way sync propagates changes from either side without deleting contacts; if duplicates persist due to missing identifiers, cleanup must be done in the respective apps.

Which GAL contact types and fields are mapped to IBM MaaS 360 by sync.blue®, and is custom field mapping available?

sync.blue® maps Microsoft Global Address List (GAL) people contacts—and company records where IBM MaaS 360 supports them—into IBM MaaS 360, transferring standard fields such as first name, last name, company, department, job title, date of birth, business email, phone numbers (business, mobile, home, other), and addresses (business/private: street, number, ZIP, city, state, country); company entries include company name, email, phone numbers, and addresses; custom field mapping is not available because mapping is fixed and handled best‑effort per app.
