completeley syncronised EmClient for android? No mobile sync makes no sense these days for a busy team. We went with free Thunderbird so far. Please advise
Well having your phone and eM Client connected to the same IMAP or Exchange account will sync them. Easy-peasy!
we need to sync all multi account activity, including categories. This is not possible with a third party android app
If you are using an email provider like GMail or Outlook.com, then your categories or labels should sync with eM Client.
If your Android app does not support that, then you should take it up with them.
We need to sync categories into android, not the other way around
One solution is to use GMail. Any category you assign in eM Client will be synced with the server, and then be passed on to the Android app.
