Hi, we have 2 exchange 2007 mailbox servers and one that with only hub transport and client access roles. User use the CAS roled server for OWA and active sync externally. Everything works fine, and I am now experimenting with Outlook Anywhere, using Outlook 2010. Configuring the connection goes ok, mails work and I am also able to see my own calendar. Problem is, that i can not see other users shared calendars. As default, everyone is able to see free / busy information of each others calendars, just by adding calendar in outlook 2010 (right click calendars-> add calendar -> from address book...), but when connected with Outlook anywhere, it opens the calendar, says "updating..." but fails saying "no connection". Now if I add my username to the target calendars permissions, with "reviewer" privilages or "above", it works. But adding "Default" and/or "anynomous" users "reviewer" did not grant access to the calendar. Then again, if I add my username to a group, then set the group as "reviewer", it works. How ever, we do not want to grant everyone "reviewer" rights, we would just like to "extend" the default "free / busy" information to be shows over Outlook anywhere. Is there a way to do this? Am i missing something?

Within the domain, you can hold the Ctrl key, click the Outlook icon in the system tray, select Test E-mail Autoconfiguration, clear the Guessmart checkboxes, enter your e-mail address and password, and you'll see the URLs that are being presented for everything, including the web services pieces.Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

The Default permission is "Free/Busy time", so it is strange that you can open the shared calendar folder in the way you mentioned. Anyhow, we can check the free/busy information in the way below: Compose a new meeting request; Add attendees; Switch to Schedulig Assistant box. Here we can see the free/busy information like the picture shown below: If the issue continues, you might encounter availability or autodiscover service related issue. you may do what Ed and James suggested. and please also test the free/busy information in LAN when connect via TCP/IP. It would help us isolate the fault. Thanks. Fiona Liao TechNet Community Support
