Lync 2010 Address Book Sync Workaround

Regarding the silly time it takes for Lync to update the database. Please follow these steps: Exit out of Lync, making sure it’s gone by right clicking it in the task tray and choosing exit

First, execute the following command from the Windows Command Prompt run as an administrator (or manually add the GalDownloadInitialDelay registry key). Setting this value to 0 will force Lync to immediately download the address book.

reg add HKLMSoftwarePoliciesMicrosoftCommunicator /v GalDownloadInitialDelay /t REG_DWORD /d 0 /f
