Thanks Stuart

Sarah Lahn

I have successfully transferred all my 36 GB mails data into Outlook 2019. Simple GUI and fast conversion process. The best thing is that the software keeps original folder structure even after conversion.

Julie Bergan

Needed to convert my Thunderbird mail to a format that would work with outlook 2019. Did exactly what I needed and faster than I even thought.

Kane Brown

Whenever we have exit interviews, we clone their email account on Thunderbird and convert it all over to Outlook mail. That way it’s searchable and we can pull relevant emails for the next person in the position. This software (in business version) allows for us to do this from multiple workstations and very easily if we are aware of the host and destination account names. All done in a few clicks from the program interface.

Sam Tsui

I love that the spacing, text symbols, bolded and italicized words were all kept within emails in the correct spots, along with pictures, quotations and other formatting. The original markup of the messages goes largely unchanged. Also, many emails may be converted at once to the Outlook format.

Justin Caruso

It helped us manage many mails in lesser time. With this we don’t miss any important mails from our company manager or from the CEO.

Gabby barrett

The best thing about this software solution is the ‘filter’ option. Since in a big organization we receive more than 1000 mails daily so reading all of them wastes a lot of time so by using this, we, in the organization can read all the mails that are relevant to us only. It also helps us to manage the emails in the folder so we can access them easily.
