Public folder address book not updating
Outlook 2011 does not use Exchange Cached mode and directly connects to the Global Address Book (GAL) via LDAP connection.
In this case your global address book will update each time Send/Receive is pressed.
In addition to this there a a few methods by which your Outlook clients get the offline address book.*Note: Unless you are NOT in cached mode.
Outlook 2003 (and older)* clients get their OAB from a public folder, Outlook 2007 (and newer) clients can get their OAB from 'Web-based distribution' (basically form the website on the Exchange (or Exchange CAS) server.
In that case, you can completely reset it by deleting the files making up the OAB or by recreating your mail profile.Rather than waiting 24 hours for Outlook to update the Offline Address Book on its own, you can force an update via the Send/Receive menu button.You can disable the option “Download changes since last Send/Receive” to make sure you get a complete fresh copy of the OAB but this could take longer to download.In general, Outlook will automatically update the Offline Address Book (OAB) for Exchange accounts once every 24 hours.When it didn’t or when you want to make sure you do have the latest OAB available, you could manually trigger an update from within Outlook as well.If this is happening, then you may notice missing, non-existent and/or incorrect entries.Synchronizing your Outlook (cached) address book with the Global Address book may fix these discrepancies.There is not enough free memory to run this program. The error appears whenever clicking or expanding a folder (public folder or mailbox folder) except for the Inbox.When the error occurs, mail in the Outbox also doesn't get sent until Outlook is restarted.Instances of mail that is bounced back to the sender may also be fixed.Please use the steps below to update your Global Address Book.
