Hi, I am currently getting the following error when doing a Send/Receive on Outlook 2003: Task 'Microsoft Exchange Server Reported Error' (0x8004010F) : 'The operation failed. An object could not be found.' I have managed to work out that the error only happens when doing the "Download Address Book" part of the sync. If I try to sync inbox/sent items/etc individually then I do not get the error but when I select "Download Address Book" I get the error each time. If I leave the window open for around 5 minutes then it will close itself. I have confirmed that the offline address list is fine and has everyone in it. Before the issue came about we have a problem with the OAL where some users would not show up on the list. After re-creating the OAL on Exchange it has sorted that part of the issue but now we are getting the above. It is only happening with Outlook 2003 clients and 2007 and 2010 are working ok. I think it may be something to do with the OAL set up as it has only happened after I created a new one. We are currently running Exchange 2010 SP1 RU5 with 2 Mailbox servers configured in a DAG and 2 CAS/HT server in an array. Any help would be great. Thanks

Fixed. I had to go to "Organization Configuration" - "Mailbox". Right click each mailbox database and select properties. Click Client Settings and add in the Offline Address Book.

Hi Gary, I have had this issue for a few months and I have exhausted all avenues I am aware of to fix this, when a client PC opens their outlook, it asks for a username and password, but this is soley becuae of some sharepoint related error, after the autehentification has failed you can see the reason and outlook reports that "Task sharepoint reported error (0x0004010f) : "The sharePoint List (Companyweb - Tasts) cannot be found Since I dont have any experiance with sharepoint I am at a loss. I see you have fixed it But I am afraid I have no idea where you did that Could you please explain where you did this? Thanks James
