Global address book not updating when running in cached mode asp net onrowupdating
GAL Objects are directly viewable in the Exchange Management Console/Shell and OWA and Microsoft Outlook BUT ONLY IN ONLINE MODE – The GAL will only present objects that have AD Attributes beginning with ms EXCH* (and some others) populated that it uses to filter on.If these attributes are present, then the AD Objects that are Mail-Enabled or Mailbox-Enabled will appear in the GAL – and ultimately the Offline Address Book.See: Exchange 2010 Offline Address Book replication/distribution schedule?
Support for Outlook 2000 was dropped with Exchange 2007, Exchange 2010 only supports Outlook 2003 (post SP2). In the diagram below you can see this server is performing public folder AND web based distribution, this is probably because you ticked this box when you installed the product.
Like the answer in the linked question, I know that the mailbox role needs to get a copy to the client access role, but both of these roles exist on the same server in this instance (there's also only one server at this Exchange org).
So, the real question is, how can I manually force updates to get the OAB on the server and the OAB on the client to show a new mailbox immediately (or within an hour) instead of saying to users "they'll show up in the GAL tomorrow"?
(This could take several minutes) Step 2: Uncheck the box next to Download changes since last Send/Receive.
When changes occur within the main Global Address Book (GAL) on the Office 365, computers running Outlook 20/2016 may not automatically receive the updates.
