You use Microsoft Outlook to connect to a Microsoft Exchange Server mailbox. When you start a manual download of the Offline Address Book (OAB) from an HTTP(S) location, the progress bar that appears in the Outlook Send/Receive Progress dialog box seems to freeze or becomes stuck. The download never finishes, and the local OAB files are not updated.
There are a couple of known causes of this problem.
- Wireless devices on the computer have outdated drivers
This issue may occur if old or out-of-date device drivers for wireless peripheral devices are installed. This includes keyboard and mouse drivers.
- Policies for the Background Intelligent Transfer Service (BITS) are configured on your computer
BITS policies allow you to control the download rate for updates. If the policy values are not configured correctly, they could effectively prevent downloads from finishing.
- The Background Intelligent Transfer Service service is not Started
If the Background Intelligent Transfer Service service is not running, then the OAB will not download.
To resolve this issue, use one or more of the following solutions.
- Update device drivers for wireless hardware
Plug in your wireless receiver and then visit the following Microsoft Windows Update website to check for updates:
Install the update that is displayed as Optional Hardware Update and has the following title:
Microsoft HID Non-User Input Data Filter
Or, install the latest IntelliPoint or IntelliType software. To do this, visit the following Microsoft website:
If you are using a third-party keyboard or mouse, visit manufacturer's website and download the latest version of the device driver or the latest update for the device.
- Check your registry for any BITS policies
If you are using a HTTP(s) location from which to download the OAB, the OAB download process is handled by BITS. In this configuration, you will want to determine if you have any BITS policies configured.
BITS policies are found under the following key in the registry:
The following DWORD values may be configured under this key:
If you find EnableBitsMaxBandwith = 1, BITS download throttling is in effect and the other values are used by BITS to manage downloads. Please contact your system administrator to disable BITS download throttling to see if this resolves your OAB download issue.

You can use the following steps to determine if you are using an HTTP(s) location to download the OAB.
- Start Outlook if it is not currently running.
- Hold down the CTRL key, right-click the Outlook icon in the notification area on the right side of the taskbar, and then click Test E-mail AutoConfiguration.
- Click to clear the Use Guessmart check box, and then click to clear the Secure Guessmart Authentication check box.
- Click to select the Use AutoDiscover check box.
- If not already entered, type your email address and password, and then click Test.
- On the Results tab, note the path for OAB URL.
If the OAB URL value begins with HTTP, then you are using an HTTP(s) location to download the OAB. If the OAB URL value is Public Folders, then you are not using an HTTP(s) location to download the OAB.
Note Outlook 2016 and Outlook 2013 only uses an HTTP location to download the OAB.
