I am not saying that IceWrap is a bad service by any means. However, as business requirements evolve, organizations need the right options or risk falling behind. Office 365 provides exactly what organizations want, but getting there on time without dataloss is quite a challenge.
If you are still uncertain about whether to continue, I have compiled a list of reasons directly from your peers that made them choose M365 over IceWrap.
Why Microsoft 365 is Way Better than IceWarp Server?
There may be many users who want to migrate IceWarp to an Office 365 account for such reasons-
- Microsoft 365 is a subscription-based email service that combines a comprehensive suite of applications with cloud services. On the other hand, IceWarp is better suited for small businesses, enterprises, or firms.
- Furthermore, Office 365 is available for Windows and Mac users, offering desktop-based applications. However, IceWarp is available in the cloud and has a desktop application for Windows users only.
- MS Office also provides updated versions from time to time to stay updated with the modern Outlook applications.
- Even O365 is a better cloud storage than IceWarp due to its collaboration features. It provides options to share mailboxes, calendars, and contacts, as well as edit documents in real-time through collaborative tools.
