I am receiving the following errors on a few machines (all running XP & Outlook 2007).
"Task 'Microsoft Exchange' reported error (0x80040115) : 'The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.' "
"Microsoft Office Outlook cannot download your offline address book. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
Points of note:
1.) This happens when I go to Send/Receive->Download Address Book -> OK
2.) This also happens to one user when trying to schedule a meeting (sending the request).
3.) After rebuilding one Outlook profile, the address book updated the first time (we could see one additional contact that wasn't there before the rebuild), but the error still reoccurred after the initial rebuild.
4.) One of my users CAN NOT work in cached mode because it will not download new information from the Exchange server. It will say "This folder was last updated on (date)(time)."
However when I take the user out of cached mode, Outlook functions normally. This is also the SAME user that I did the Outlook Profile rebuild on.
I feel that all the issues are related to some kind of common connection problem between the users' Outlook and the Exchange server. Please let me know if additional information will be useful in resolving this issue.
