Engineer Small-Business (50 or fewer emp.) 11/28/2025 "Effortless Calendar Sync Across Platforms" 5/5 What do you like best about OneCal? I really appreciate OneCal for its great user interface and ease of use, making it an efficient and user-friendly tool in our daily operations. The reliable syncing feature is incredibly valuable as it ensures that all calendar entries are consistently up-to-date, eliminating scheduling conflicts and simplifying the management of multiple calendars. Setting up OneCal is straightforward and quick, taking just a few minutes, which is a significant advantage when introducing it to new customers. Once configured, it operates seamlessly in the background, reducing the need for constant supervision. The ability to sync calendars across Google Workspace and Microsoft 365 (Outlook) is particularly useful for us and our clients, as it helps maintain clarity on availability across different companies and shared environments, like room calendars, which are often managed among multiple organizations. OneCal effectively addresses the challenge of managing multiple calendars, providing a streamlined solution that enhances productivity. Furthermore, with its high reliability and ease of setup, it offers a hassle-free and efficient tool that I would confidently recommend with a solid score of 10 out of 10. Review collected by and hosted on G2.com. What do you dislike about OneCal? I find the limit of 50 calendars quite restrictive for some of our use cases, which makes it challenging when needing to manage more. Additionally, the absence of features to directly add or remove calendars from an existing sync session is inconvenient. Currently, if I want to change the calendars involved in a sync, I have to delete and set it up all over again, which is time-consuming and inefficient. Review collected by and hosted on G2.com. What problems is OneCal solving and how is that benefiting you? I use OneCal to sync calendars between Google Workspace and Microsoft 365, avoiding scheduling conflicts and managing multiple calendars effortlessly. Its easy setup and reliable background syncing ensure seamless availability visibility across different companies. Review collected by and hosted on G2.com.
