Hello again. The last few days have given me lots of new things to do, so apologies if you are being inundated with blog posts!
So today I went to enable a new Exchange 2013 Hybrid configuration. I used the Start Menu launcher for ‘Exchange Administrative Centre’, which to be honest I don’t usually do. This took me to https://localhost/ecp/?ExchClientVer=15. I then went to Hybrid and enabled the Hybrid Configuration. I logged into Office 365 and was greeted by this friendly message of doom:
This error is quite easily solved; do not use localhost as the server name when you access the ECP. Use your client access namespace instead. For example, if my CAS name was mail.misstech.co.uk, I would browse to https://mail.misstech.co.uk/ecp/?ExchClientVer=15.
Just be sure to put outlook.office365.com and your CAS name into your Intranet Zone too or you’ll then get an error about Cookies!
Thanks for reading!
Thank you so much! Your instructions were exactly what I needed, this was really helpful 🙂
