Here we also talk about some good points of MS Outlook which is defeating Mozilla Thunderbird day by day.

Why does MS Outlook attract Thunderbird users?

Mozilla Thunderbird's free-for-all has been a boon to the public since its inception but with the modern age, email service has been replaced by many advanced features that are offered in Outlook.

MS Outlook is an application of the Microsoft Office package suite that can be used in more than 30 languages.

It includes many advanced features like Time Zone, Meeting Arrangement, Sticky Notes, Appointment, etc.

Apart from running on the local system, the Outlook application can also be used on Windows and Android phones.

It also provides the facility of Exchange Server to protect the data from unauthorized access.

Apart from this, there are also some other points that are the reason for importing Mozilla Thunderbird email into PST.
