My idea (Thunderbird on multiple devices) has nothing to do with Apple devices. All mine use Windows 10, and I want to share Thunderbird to all of them.
Out of curiosity, does your tablet use an ARM CPU? Thunderbird doesn't currently have an ARM build, which would be a blocker to having it on that device. However, if all your devices are using Windows 10 with a standard Intel or AMD CPU, there's no reason you can't install Thunderbird on all of them.
(And when we add Firefox Sync later this year, you'll be able to keep all your profiles and preferences in sync)
I was looking for this subject. I want to synchronize a Windows comp. as a basic (!) and (yes) with a Mac to have the same information. The emails are the same, not sure about deleting on one and so on the other, but the calendars (appointments, tasks etc.). They need to be the same. I imported "profile" from windows to the Mac, but that's not enough! Is the a protocol to work this out?? 🤔
I would like this functionality too — however, if Thunderbird is run on multiple devices using the same POP mail account, and mail is deleted from the server after retrieval (due to storage limits), new incoming messages will only appear on the device which retrieved them.To address this problem you would need to run a Thunderbird proxy on your local router or file server which retrieves incoming mail on demand by the client device and stores it in a central location on your LAN, so all of your devices with the same mail user profile would be in sync.We would love to have a feature like that, but do not want to store user profiles in the cloud.
I have been using Thunderbird Portable for multiple devices by keeping it on removable media, but there are issues with this. First, all the devices must use the same operating system. Second, the removable media should be very fast, otherwise TB gets annoyingly slow. Third, I have had problems with index errors. The main time I see errors is when I am using the Portable TB version on a different computer. So far, the Properties -> Repair function has enabled me to recover almost all of the time. I have gotten in the habit of making frequent backups, and I have had to use a backup to recover from corrupted files when moving to a different PC. My process now is to take extra steps when moving my portable TB to a different PC: First, use the Windows Properties Check tool on the media; next Compact Folders (I like that the Files Menu has a "Compact Folders" item that lets me select a main folder and all subfolders get compacted); next perform Properties -> Repair at least on folders and subfolders that have been recently active. I do this when moving from PC 1 to PC 2, and then again when returning from PC 2 back to PC 1, and this has been reliable. I would like to have a "Repair Folders" item as this would be a big time saver.
