QNAP TS-873 on firmware version QTS 5.2.3.3006 with installed app “Notification Center” 1.8.0.2982.
I’m trying to set up mail notifications and getting an error “SMTP service account: [mail address] already exists” when trying to add it in “Service Account and Device Pairing”.
But in the Notification Center, this address is not registered yet.
I suspect that the mail address I’m trying to use was configured in the old QNAP SMTP settings (Firmware 4.x ?) but now in Firmware 5.x I can’t remove it anymore.
Does anyone have an idea how to remove this old config?
