Hello, All!

We are starting migration from Exchange 2010 to Exchange 2013.

We've already installed 3 Exchange 2013 Servers and configured them also.

One problem that I'm facing now and it's: Do I need to configure External URL for ActiveSync on Exchange 2013?

As far as I know, that External URL of ActiveSync is being used, only when Mobile Phone is configured for a first time.

And after that the only URL that is used it's Internal one.

Am I right? Where I can find accurate information about External and Internal URL's usage?

BR,

Pavel
