It could be because of the program’s discontinuation or having a security problem or other issues.

The client is compatible with all the most well-known protocols for email and websites in addition to POP3, SMTP, IMAP, Exchange, Office 365, Apple iCloud, and much more.The program is no longer available for download. Thanks for the hard work that you’ve clearly put into making this program which is a huge thank you to all of the team. I’ve used the older T-bird for many years, and when I bought an upgraded laptop, I was looking for an email client more compatible with my needs of today. The simple but effective user interface can boost the efficiency of your work. Additionally, you are able to export all your data in different formats or make backups and restore them. The program is now compatible with PGP and lets you import or create your PGP keys to send signed and encrypted email messages. In addition, for the cost that is 25.00 EUR, you will get an unlimited license. I am a happy customer of eM Client, which I have been using for a long time and I am happy with it. I use private calendars in iCloud and a calendar for work using Exchange which is why eM Client is almost the only application that can do this.
