I am having the same problem and have nearly exhausted all evenues. What is interesting is the BT tech support are saying there is no such block - I am also in Australia.
The most recent thing I have tried in conjunction with the tech support is changing the encryption from SLL to Auto. I have to be honest and say that I'm not confident it will work.
One thing I have found is that I can download emails to my mobile device via 4G but not wifi which supports the regional block theory.
-Good luck, if you find a fix please let us know!
The password reset is requested to sync the password with the BT Mail and your Client servers. So, that is a primary requirement. And, that it is an online password reset which you try on a device yourself and not a Service Desk password reset as that will not work. Once, that is fixed ( I mean the password sync ), you are okay to try the email settings.
In my case I did do the password reset as requested and it did not have any effect. I do not believe this issue is an Authentication problem, though without access to logs and some packet sniffing it is hard to tell. If it is a comms issue the changing of a password could only serve to confuse the picture mid diagnosis. Hence the comment. Password sync issues clearly could be remedied by propogation of a new password but this does not appear to be one.
This isn't a password issue, hence not anything to do with primary requirement. Why would a new password be required when not on the UK?
As has been said, it has sometimes worked for people, then not - others have no problems, and some have no access it seems.
An email password will be required anywhere to access your email. It is a suggestion that you reset the password online to make sure that the password is in sync. As far as the email clients are concerned, if you can help yourself, no worries. It is a suggestion for folks you cannot help themselves and need assistance.
As the saying goes, never help people who can help themselves
Naturally a password is required for access, but I can't see why it needs a reset - and to be in sync with what?
It is normal that Authentication servers are federated in large deployments such as this. It is possible under some failures for them to become out of sync depending on the federation approach. This presumably is why they often recommend a reset, but as I said this does not appear to be a password sync issue and so changing the password would be counter productive as it introduces another variable into the equation.
Who often recommends a reset?
How do the passwords become out of sync? What's this federation?
