base 64 encoded mail messages garbled

Greetings,

My users recieve an occassional message from a local bank with a link to a message in the bank's secure communication system.  It usually looks like a html formatted message with a table showing the list of messages and each message is a link which takes you to a log in page where you use your credentials to access the bank's portal and read the messages.

Recently the messages have been coming in garbled.  Apparently the issue is caused by "Content-Transfer-Encoding: base64".

The messages appear garbled in Outlook and OWA.  I read that it was just a problem with Outlook, but the messages are also garbled in Thunderbird.

The bank can't or won't change anything.  Office 365 tech support didn't have a solution.

If anyone can think of any other steps I can take to rectify this situation I would greatly appreciate any advice.

Best regards,

Sky

Is it just not decoding the base64 content?  So it's actually showing the YmFzZTY0IGVuY29kZWQgbWVzc2FnZQ== instead of the actual message?

If you decode the base64, what does it decode to?  Is it an image file or PDF?

Also, just to be clear, is it the message you receive via eMail from the bank that is encoded?  Or the link you click on takes you to a web page that shows an encoded message.

Yes.  That is correct.

It looks like this:

When the message looks proper in the inbox it is an html formated mail with a table that shows your list of messages, usually just one.  The columns are sender, subject, date and one of the columns is a link which takes you to the log in page of the secure portal for the bank.  There are some graphics to make the page look nice, not jpeg probably but gif perhaps.  

How would I decode the message after it is recieved?

Thanks very much.
