Outlook Web Access Calendar availability gets "You don't have permission to perform this action"

Posted on 2008-10-10

Have any of you seen this or have a solution for it. In OWA users are not able to see the availabiltiy of other users calendars or even their own for that matter. When you go in and create a new appointment then click the availability tab you get "you don't have permission to perform this action". I'm assuming this is some kind of IIS Permissions issue since there are absolutely no problems when any user uses their outlook client for scheduling appointments.
 Thanks in Advance

Is the error occuring for all the users in your environment.

Try using the OWA Web Admin Tool and see if there are any permissions setting set on your Calendar

Although this is a great tool and very informative it does not have any focus on the Calendar and this is the only place that we are experiencing any issues. I appreciate your input but still need help in getting this issue resolved.

Further Findings:
ok i've been digging into this a bit more and it seems the free/busy is part of the Public Folder structure so I've been looking at the permissions on that. Now the following is what is rather odd. If I logon to OWA and click on Public Folders I get a new window displaying the public folders just fine. I'll leave that window open and can continue to get to it as much as I want. Although as soon as I go back and check the availability  tab in a new appointment window the public folders then become a 403.4 - Forbidden error stating "The page must be viewed over a secure channel.

This is one a Front End Server with a certificate and the back end server does not have a cert and none of the require ssl options are selected.

We've figured out that this was a problem with Replication from the top tier server where the Public Folder Hierarchy is stored. It was not being properly replicated down to the other servers. Once the replication was put in place everything started to work. The replication was created for the Free/Busy System folder.
