From: Brown, Larry [mailto:[email protected]] Sent: 15 April 2009 20:30 To: MS-Exchange Admin Issues Subject: RE: Global Address List Changes Yeah...same thing goes for the GAL. If we add a new user or change an existing user, with Cached mode enabled the change doesn't show up until the next morning. Can be a royal pain... ________________________________ From: Sobey, Richard A [mailto:[email protected]] Sent: Wednesday, April 15, 2009 10:01 AM To: MS-Exchange Admin Issues Subject: RE: Global Address List Changes It’s Working As Intended I’m afraid to say. The OAB is only updated server side every 24 hours or so and then the client has to fetch the changes and update its cached copy, which could be another 12-24 hours. That explanation is extremely simple, but the upshot is that you could be waiting up to 48 hours to see changes in the OAB. You can configure Outlook to always use an Online Address Book (my term, not Microsoft’s) even if it’s in Cached Exchange Mode, but when I had a play with that I didn’t have much luck getting it working. I didn’t spend too long on it anyway! Richard From: [email protected] [mailto:[email protected]] On Behalf Of Chris Blair Sent: 15 April 2009 14:47 To: MS-Exchange Admin Issues Subject: Global Address List Changes I am seeing this issue only on Outlook 2007 using Cached access. Outlook is updated with all the latest fixes and Exchange 2007 is also fully updated. Whenever we make any changes to an Exchange object, the changes are not reflected in Outlook until we delete the OAB files and let Outlook rebuild them. For example, today I am deleting an E-Mail contact, and creating a mailbox for the user under our domain. When I look up the user in the GAL, it still lists the person as a mail contact under the external domain, and any email sent to that contact fails. I did try running the commands to update the GAL and OAB on the Exchange server, but still no luck. (Update-GlobalAddressList "Default Global Address List and Get-OfflineAddressBook | Update-OfflineAddressBook) I also setup a 2nd profile on my machine, pointing to the same mailbox, but didn’t check the box for using Cached Mode. The changes to the address list were reflected immediately. I would rather not manually delete the OAB file on each laptop user. So I am hoping for some other fix.
