I have recently switched to emClient and I am not sure it was the best choice. I can send and receive emails just fine, the interface is nice but emClient seems to be unable to synchronize my contacts from Outlook.com.
I have 12 Contacts in there which seem to be random picks from my entire list of around 200 contacts. Adding/removing the account didn’t help, the repair function also didn’t work. At this point I am at a complete loss.
