I have only the last 15 - 20 mails on the server, because I use POP and can not change to IMAP. I thought, it doesn´t matter, if they are marked as read or not.
I have tried, to clear the app data in the android apps section without luck.
Only the newest mails are interesting for me on the phone and on the smartwatch. (If read -> delete. If I need it a second time, I can use a different mail program and receive the mails again or can open the strato webmail or go to the main-pc with all the millions of archieved mails of the last years. The pc is only receiving mails, if a wlan-ping to my phone is positive. In that case, the stato server is mostly empty and my mobile phone mail program too. I like it when it is clear.)
Unfortunately the app does not support POP, but for the last mails, I thought, I can use imap too.
After receiving and deleting all mails from the pop3.strato.de, the imap.strato.de should also be empty.
Please excuse my bad english.
