Users want to migrate from FastMail to Office 365 even though FastMail predates many of the leading email services. But it still cannot compete with Exchange Online’s advanced features.

A full-featured business account requires more storage space than the basic plan offers, which is only 2GB per user. Additionally, for the price that users pay, they receive only email services.

A business shouldn’t integrate chat applications, cloud storage, or other productivity applications.

Consider Office 365 as an alternative. Aside from supporting several of Microsoft’s other products, it also supports third-party applications for even greater functionality.

Moreover, Office 365 includes some of the most sophisticated security and privacy features available. Among the improvements are improved anti-malware and anti-spam features.

All things considered; Office 365 is far more cost-effective than FastMail.
