I receive odd errors every time I opened my Exchange 2013 EAC when attempting to perform my Exchange 2007 to Exchange 2013 migration.  It occurs on a single computer, and only in IE.  Firefox and Chrome do not exhibit the errors, and IE on the servers do not either.

The computer is Windows 8.1, with IE 11.

In the EAC the error was consistently stated there was error in code "PAPADDING......" , when you click ok; there next error was "expected ; ".

After much frustration, I Uninstalled Amazon 1Button App 1.08 add-on from IE, and it resolved the issue.  Amazon 1-Button App version 2.0 does not exhibit the

So your problem is resolved, then?

Hi Smith,

Thank you for your sharing. Is there any other problems with your environment?

If you encounter a similar problem next time, we can open IE without add-ons (run iexplore -extoff) to narrow down the problem.

I my testing, Run IE without Add-Ons did not work. Compatibility Mode caused other issues.  Alternate browsers worked, but not perfectly.

Only after Uninstalling Amazon 1-Button was the issue resolved.

Yes Ed, I was largely just sharing.  I did ultimately resolve my issue on my own.
