Hi
We have a new Exchange 2013 installed in our environment, everything was straight forward and worked from the start.
At least we thought so, after starting using the new environment we saw that out of office didn't work
When you try to change the out of office (Outside our network) we get the message that Exchange server is unavailable and we need to try later.
Have tried to find information about this online, and changed all url's to the external url.
This without any luck.
Is there anyone of you that uses exchange 2013 with out of office from external networks?
Appreciate all help that we can get.
