Email problems?

[#1]

Anyone else having problems with Email access?
Thunderbird can't connect (Authentication failure) and Webmail gets me a
"Sorry, this page is currently not available!" page.

[#2]

no problems with webmail here.

[#3]

Thunderbird working again (Via POP) but webmail still giving "this page is currently not available!".

[#4]

Any joy with webmail? I tested this from the office and from home last night but couldn't replicate the error.

[#5]

Just checked, all OK now.
I only use webmail if Thunderbird fails, so I haven't checked it since yesterday.
