Selfhosted Family Email and Calendar

Hello friends! My first attempt at a selfhosting project is up and running. My goal was to make a private email and calendar system for my family. As it is private, as in we only email each other, I don’t have to worry about delivery blocks or spam. The system needs to support 12 users. Turned out it was easier than I though it would be! Here is my stack: Thinkpad T480 with 64G ram and 1tb ssd Windows Server 2022 eval MailEnable Standard Edition which is free software from Australia www.mailenable.com/standard_edition.asp Thunderbird Mobile www.thunderbird.net/en-US/mobile/ Right now we are using the native android calendar app but I would love suggestions for a better calendar app. Happy Hosting!
