Global Address List is not uploading any new users created in Exchange server 2010

When i create a new user email account on the exchange server 2010. The users do not show up automatically in the GAL even after waiting 24hrs. The only way to get them showing is to force update OAL (Offline Address List ) in exchange server. Is there something thats causing exchange not to update the GAL in outlook for all users. Now today a user came up to me saying new hire email account isnt showing in the gal i did the force offiline Add. List update and also  download address book in outlook but user is still not showing in GAL. Please Help, Thanks!!

You may want to re-create the OAB if this keeps happening.

Before you try that, check OAB folder and check for last modified date. You can also enable expert level setting and check for errors.

We disable Cached Exchange Mode for security reasons (don't want email cached on local HD) and this has the side effect of fixing all those bizarre GAL propagation issues.

We do this domain-wide.  It can also be done at the desktop: Control Panel | Email | E-mail Accounts | Change... | Offline Settings uncheck Use Cached Exchange Mode.
Will SzymkowskiSenior Solution ArchitectCommented:
There is a reason why Microsoft has cached mode enabled by default. Not using cached mode you are creating a connection directly on the Exchange server which increases the load for memory and cpu. I guess this could be a work around but OAB is still broken.

Interesting, I was not aware that this was the reason they enable cached exchange mode by default.  Their documentation states that it's for offline access to email.  Do you have a reference?

We see no performance issues or server memory/cpu spikes as a result.  (CPU/memory among other things are monitored with Nagios and graphed for trend analysis with Cacti.)

For security reasons, we don't have sensitive and protected data stored/cached on local hard drives.  And, we don't have GAL issues either! :)

Although you are correct, this is not the only reason why it is enabled by default. Outlook in online mode requires a consistent connection to Exchange which does require resources on the client and also on Exchange in order to process these connections.

Cached mode is also enabled by default because it provides a better user experience as well.

See link below for additional details.

Every business has different requirements and if yours is security and it is working for in your company then you probably have adequate resources and network to support this.

However i would not be running Online mode on all mailboxes for a company that has thousands of mailboxes.
