Outlook Error 0x8004010F - Downloading Offline Address Book
· ☕ 3 min read
It originally started as a minor problem. One of our employees did not get updates for the offline address book (OAB) from the Exchange server. One person was missing from there and it was just one PC that had this issue. Naturally, we tried updating OAB. Got the error 0x8004010F (The operation failed. An object could not be found). Strangely enough, we then tried to update OAB from other PCs and got the same error. However, all those PC had no problem showing that contact on the list.
