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 the update mechanism appears to be broken for you, it could be because of a corruption in your OAB or in your mail profile.
For me, new colleagues are not showing up and the contact pictures aren’t displaying either.
They do for my colleague sitting next to me, so I don’t think it is a server misconfiguration or something like that.
Dear All, I have an issue which is annoying a lot, OAB is not updating GAL on Outlook 2007 in Cache Mode. Exchange 2010 Outlook 2007 - Cache Mode OAB is distributed via Web based and Public folders.
I disable cache mode and it works fine but I don't want to keep it disabled, I also tried by delete the OAB file in C:\Users\username\App Data\Local\Microsoft\Outlook\Offline Address Books and download OAB manually rather then waiting for 24 hours, it's still same.
When you have Cached Exchange Mode enabled, Outlook by will by default cache the main Global Address List as well.For the most part, it only makes sense to move it if the C: drive is full.Outlook 2013 IMAP and EAS (Outlook.com/Hotmail) ost files are moved using the Force PSTPath key.This situation however is extremely rare since the default maintenance time on Exchange is at AM and updates and downloads are usually performed during working hours.Even though Outlook is the last in the chain, it is often the first level where the troubleshooting takes place as usually this is where the request is coming from.
