Global address list is not updating
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.
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?
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).
In this guide, the relevant timings are explained and instructions are given in how you can directly force an update and resync, which can be very handy when troubleshooting or when you work in an Exchange environment which sees a lot of user mailbox mutations.
This means that in the worst possible scenario, an update to the Address Book won’t become available to the user until 48 hours after the change.
I created a new OAB with both distribution methods this morning.
I ran the commands you recommended and tried it about 4 hours after that. As another way to troubleshoot the problem, I created a new profile for Outlook.
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 I have tried deleting the OAB files, but when I download the address book, it still has the outdated version.If the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.In that case, you can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.
