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.
I might have a problem with my Offline Address Book in Outlook.
I created a new OAB with both distribution methods this morning.I created an alternative OAB, connected it to the Default GAL, made that OAB the defualt OAB, and tried to download it through Outlook. The first thing I would do is switch to either web only or mixed (web and public folder).Then once set, run get-offlineaddresbook | update-offlineaddressbook Wait 20 minutes or so for it to update, then check in the Application log to see if there are any generation errors.We have another server in the wings waiting to be deployed, but we need to address the problem in the meantime. If it does not, then it is the generation or distribution process that is failing. OWA reflects the information correctly, but Outlook does not. I have tried deleting the OAB files, but when I download the address book, it still has the outdated version.I'm wondering if anyone has anyone has any tips that could help me address this issue. Are you using web or public folder distribution for the OAB? If you are on Outlook 2010, any reason you are still using public folder distribution?Instances of mail that is bounced back to the sender may also be fixed.
