Reset a conference ID for a user in Skype for Business Online
For information about resetting conference ID in Microsoft Teams, see Reset a conference ID for a user in Microsoft Teams.
A dynamic conference ID is included at the bottom of meeting invitations along with the dial-in phone numbers that can be used by callers to call in to a meeting. When the user dials the phone number, the auto attendant for the meeting will ask the caller to enter this conference ID so they can attend the meeting.
If your conferencing provider is Microsoft, your users' conference IDs are set to Dynamic Only by default. Unfortunately, there's no ability to change it in the Skype for Business Admin Center or using Windows Powershell to become static, as this is now unsupported. Conference IDs are automatically set only for Skype for Business users enabled for Audio Conferencing.
Resetting the conference ID for a user
In the Skype for Business admin center, click Audio conferencing > Users, select a user, and then in the Action pane under Conference ID click Reset.
In the Reset conference ID? window, click Yes. A conference ID will be automatically created and an email sent to the user with the new conference ID. By default, emails are sent to users, but this can be turned off.
After you reset the conference ID, an email with the new conference ID will be sent to the user. This email will be sent to the primary email address, in many cases, their Office 365 mailbox. The email contains the new conference ID, default dial-in phone number(s) and instructions to use the Skype for Business Meeting Update Tool to update existing meetings.
We are frequently updating how you can manage features found in Skype for Business Online, so the steps here might be a little different.
What else should I know?
You can send all of the conferencing information to the user in an email that includes the conference ID and dial-in phone numbers by clicking Send conference info via email for the user in the Action pane. It doesn't send the PIN.
A conference ID will contain 7 digits, and you can't change its length in the Skype for Business admin center or by using Windows PowerShell.
After it has been reset, you can see the new conference ID listed under Conference ID.
The conference ID for a user for audio conferencing can be viewed at the bottom of the Action pane under Audio conferencing when you select the user on the Users page.
After a new conference ID is created, the old conference ID can't be used by callers. You should notify users to reschedule their existing meeting invites to make sure the new conference ID is added to the invitations. The users can use Skype for Business Meeting Tool to update their existing meetings. To see how to download, install, and run the Skype for Business Meeting Update Tool, see:
Want to know how to manage with Windows PowerShell?
When it comes to Windows PowerShell is all about managing users and what users are allowed or not allowed to do. With Windows PowerShell, you can manage Office 365 and Skype for Business Online using a single point of administration that can simplify your daily work, when you have multiple tasks to do. To get started with Windows PowerShell, see these topics:
Windows PowerShell has many advantages in speed, simplicity, and productivity over only using the Office 365 admin center such as when you are making setting changes for many users at one time. Learn about these advantages in the following topics:
