## Review summary

Users broadly value the app for syncing Outlook calendars and contacts with Android and appreciate its ease of use and wireless syncing. However, reliability varies: frequent connection problems, inconsistent bidirectional sync, and deletions reappearing in later cycles undermine trust. Recurring events aren’t well supported, and the PC companion software is viewed as costly and buggy. Overall, it delivers meaningful functionality for some users, but consistency and cross-device reliability remain major concerns.

### Pros

- Core Outlook-Android Sync solves the long-standing need to sync Outlook calendars and contacts with Android.
- Easy to set up and use, with many users reporting it simply works for their needs.
- Wireless syncing over Wi‑Fi is faster and, in some cases, adds features compared to USB.
- Widely considered helpful and essential for work by multiple users.

### Cons

- Frequent connectivity issues and unreliable syncing, including stalls or inability to connect to the PC or Wi‑Fi.
- Inconsistent bidirectional syncing, with reports of one-way transfers or unreliable two-way sync.
- Deletions and duplicates reappear in later sync cycles, indicating poor handling of removed items.
- Lack of support for recurring events (cannot delete or manage recurring events properly).
- PC companion software is seen as expensive and buggy, with crashes or instability.
