Global address list not updating exchange 2016 cached mode

Another way to make sure that you get a fresh copy of the OAB is by renaming the oab-files to when Outlook is closed.

They are stored in the following location: which itself holds subfolders with named after Account GUIDs.

In that case, it is recommended to recreate your mail profile.

Frequently users report recipients missing from the GAL. Scenario:– Recipients are not hidden from Exchange Address Lists– Recipients do show up in the “All Users” Address List– Recipients do show up when Outlook’s not in Cached Mode– Recipients resolve in Outlook Web Access Some recipients may not be included in the Offline Address Book when it is generated, for a number of reasons.

Outlook is helping you complete other activities and does not allow the address book update to interfere.

My computer slows down when Outlook shows the "Updating Address Book" status. In computers with slow hard disk drives, such as portable computers, or running Outlook in a Virtual machine, the process of updating the address book can slow down the computer if the hard disk is fragmented.

In general, Outlook will automatically update the Offline Address Book (OAB) for Exchange accounts once every 24 hours.

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.

The Download offline address book check box in the Send/Receive Settings - "Group_name" dialog box does not affect the 24-hour download process.

In fact, Outlook cached mode will continue to download the offline address book every 24 hours regardless of whether the option is enabled.

To improve offline address book download performance, try defragmenting your hard disk.
