Nine – Email & Calendar for Android

What is Nine?

Nine is an Android application that lets you access Microsoft Exchange‑based email, calendar, contacts and tasks from your mobile device. Developed by NextIntelligence.ai, the app focuses on delivering a consistent experience for users who rely on Exchange services for work or personal communication.

Main features

• Exchange ActiveSync support – Connect directly to Exchange servers without an intermediate cloud service.
• Integrated calendar and contacts – Sync events and address book entries alongside your email.
• Rich‑text composition – Create formatted messages using a built‑in editor.
• Security options – Supports SSL/TLS connections and can work with client certificates.
• Conversation view – Group related messages for easier reading.
• Search – Combine local and server‑side search to find messages quickly.

How it works

After installing Nine, you add an Exchange account by entering your email address and password. The app communicates directly with your organization’s Exchange server using ActiveSync, pulling mail, calendar events, contacts and tasks to your device. All data is stored locally; Nine does not host user data on its own servers.

Practical uses

• Stay on top of work email while traveling.
• Manage meetings and appointments from the same app you read messages.
• Access corporate address lists without switching apps.

Installation information

The app is available as a free download. After installation, you will need to configure at least one Exchange account to start using its features. A trial period is offered, after which a license can be purchased if you wish to continue using the full set of capabilities.

Things to know before installing

• Requires an active Microsoft Exchange account that supports ActiveSync.
• All synchronized data is kept on the device; consider device security settings if you handle sensitive information.
• The free version includes a limited trial; continued use beyond the trial requires a paid license.

Who may find Nine useful?

Professionals who rely on Exchange for email and scheduling, small‑business owners managing multiple accounts, and anyone who prefers a single app for email, calendar and contacts on Android.
