The Address Books have several separate, independent lists of names and e-mail addresses — it’s pretty confusing.
I changed the value to this setting: 1 = The Offline Address Book uses the Download Full Items download mode. I then deleted all of the files as per the article. Has anyone else experienced this issue, or have any idea why it would occur?
If you are not seeing correct contact information in the GAL for someone that has a valid email address (i.e.
someone who just received a CUMC email account, a new student, someone who recently changed their directory information) please use the steps below to synchronize your computer's locally cached version of the GAL.
I saw this related question: Exchange 2010 offline address book does not update but the answer's blog post no longer exists.
If I create a new mailbox, and even if I manually update the OAB and then go into Outlook (in cached mode) and download OAB updates, it still doesn't show the new mailbox in Outlook 2010 until the next day.
