The same problema here. The mail server will not recognise my password. This on both mobile phones and Mozilla Thunderbird. Works OK on webmail
Same issue here on Gmail app on my talk21 account. Will wait it out but pretty frustrating that this isn't the first time this has happened.
Normally the problem of not being access my emails via my email client lasts possibly a day.
However this latest one has lasted since 12 December, so hopefully I wont have to wait too long for the system to reset itself?
There seems to a little progress, I can send and receive emails via Thunderbird client.
I can send emails via eM Client but not receive any even though I can receive them on Thunderbird and Web based BTYahoo.
It is now five days since I received any emails via eM Client.
