    Hi everyone,

    we recently installed project server 2010 in our existing exchange 2010 sp1 and sharepoint 2010 environment. We did manage to sync tasks from project server to exchange using this guidelines: http://technet.microsoft.com/en-us/library/ff468700.aspx

    so if i create a task on project server it is replicated through exchange cas and shown in the outlook client,if i change the task in project the change is replicated too. if i change the task in outlook the exchange cas tries to update it on project server but fails and the following Warning is logged in the application event log of the exchange cas:

    I did search for the ExchangeSync.asmx file on the Sharepoint and Project Servers but didnt find it anywhere. 

    thanks for your help,
    regards

    Authorize that account to access the URL (or file) on the Sharepoint
    machine. Or use "Exchange Enterprise Servers" group in the local
    domain to allow access to the resource.

    The 401 status means that whatever the CAS is using for credentials
    isn't acceptable. You should be seeing errors in the IIS log on
    sharepoint.

    Rich,

    thank you for your answer, sorry for my delay!

    i do see 401 Errors in the IIS log too, but unfortunatelly they dont really help me out.

    exchange cas tries to authenticate using its samaccountname (domain\computername$) and always gets: 401 unauthorized.

    any idea?

    thanks!

    I have the sam error (500). The exchangesync.asmx is not exist in the path. I have no solution. I have a green installation, but only sync from project to outlook, but not from outlook to project. Microsoft need beta tester!

    Exists a solution of this problem?
