Assume that you use the Location Information service for Microsoft Skype for Business, and you change the default interval time to update Skype for Business users’ location information. In this situation, the first update occurs based on the old interval time, which is unexpected. For example, the default interval time is four hours, and then, you change it to one hour. In this situation, the Skype for Business clients do not update the location information until four hours after the clients sign in. After that, the update occurs every one hour.
This issue occurs because the timer of the Location Information service starts before the in-band setting of the new location update interval time is processed.
