SFB disconnection after 90 minutes

[Wan Zhung Bong]

Hi,

We have federated users (e.g. @123.com) joining a SFB session hosted by our user (e.g. @aaa.com).

In this meeting, the federated users are having discussions in the SFB session when there is no one from our side are in the meeting. After 90 minutes, the session is disconnected. 

Is there any limitation that after SFB Online detected that there isn't any hosted user in the skype session, therefore, it disconnect the session after 90 minutes?

Thanks.

For on-premises Lync and Skype the AnonymouseUserGracePeriod (A conference without an authenticated user) is default to 90 minutes under the CSUserServicesCOnfiguration (https://docs.microsoft.com/en-us/powershell/module/skype/set-csuserservicesconfiguration?view=skype-...).

This can be changed for on-premises, example to 8 hours:

Get-CsUserServicesConfiguration | Set-CsUserServicesConfiguration -AnonymousUserGracePeriod "08:00:00"

Unfortunately this parameter is not exposed in Skype for Business Online.

Thanks for the information, by any chance is there any workaround that we can circumvent?

Thanks.

No workaround in SFBO without having an authenticated user join the meeting (this could just be one of the federated users using a leader PIN).

We ran into this issue lately as well. Interesting that you can't extend that in the Online version. Hopefully that get's looked at more closely with the transition to teams.
