Global address list not updating
And since this website’s main focus is on Outlook, it makes sense to start with Outlook as well ;-).The command for the manual update procedure can be found here: Outlook will automatically download updates only unless the size of the changes is larger than 12.5% (one-eighth) of the total OAB size.In that case the whole OAB is being downloaded again.
Either leave the configuration alone, and just let Outlook users see the Default Global Address List; or else, take the time to study, plan, and test before you implement custom Address Lists.
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.
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.
