I've noticed that SfB Conference IDs remain live long after the scheduled meeting. I don't just mean by a few minutes, I can go back to old invitations from last month and still click on the link to go back into the conference. All the uploaded material is still there. Worse still, we have PSTN dial in conferencing enabled with toll free numbers so any invite particpant can go back to the old invite, dial into the conference ID (not PIN is required because the original meeting has already been had) and meet gratis.

 

Anyone else noticed this? Any way to forcethose old Conference IDs to be stop working? Or revert back to the pre meeting condition where the meeting organiser is required to start the call before people can join?

It depends on the meeting type, as the confnerence is valid for different periods of time wherether it's ad-hoc or scheduled once or is recoccuring.

 

You can find specific details in the following blog article:

Thank you Jeff. A very helpful post.

 

Your link prompted me to refine my own search which lead to a couple more articles. These may also help anyone else trying to figure out the vagaries of conference expiration.

Depending on which article you believe, conference IDs stay active for anything between 8 hours and 365 days. Anyone sending out toll-free numbers for their conferences need to be very careful.

I'm finding hard to understand, or perhaops hard to believe how the expiration of dynamic conference IDs work.

 

I have a business requirement for a conference bridge that is constantly available for our operational support team, when there's a major incident everyone piles into a call that matches the name of the major incident room and work until it's finished. So my need is really for a static conferenceID and meeting join link.

 

In Outlook if I create an all day meeting, recurring everyday for ever, I can add Skype details. By the details described here this should last for ever ! Gvien I can't test this, anyone else know ?

 

Also, I can create another all day, recurring everyday, Skype Meeting and get a new ConferenceID. So they both last forever.

 

This doesn't sound like reasonable use of one users license, so what are the limitations ?

 

The service description at https://technet.microsoft.com/en-us/library/mt634523.aspx states that meetings will end if the attendee list doesn't change for 24 hours. What does end mean ? Can I just dial in again the next day ? The Conference ID hasn't changed in the meeting booking.

 

 

Not sure I can fully answer your question but this is the most up to date article I can find on limits

 

https://technet.microsoft.com/en-us/library/skype-for-business-online-limits.aspx#bkmk_MeetingRetent...

 

However as an Office 365 E3 customer I can tell you its not all correct. I can go back to a one time confernece link from 52 days ago and it still works . The content has gone but the conference ID live. According to the link above it should have stopped working after 14 days. I have another conference ID from 75 days ago which doesn't work so the truth is that ID stop working somewhere between 52 and 75 days (for E3 customers using a one time conference link).

 

 

 

 

Were you able to find an answer to this? I'm in the same boat as you were. Our operations team needs a static conference ID/link to use 'forever'. From what I've found, the documentation lists that recurring meetings with no end-date in SFB Online expire n+14 days after the meeting was last joined. This seems like too short of a period. Furthermore, as another suggested, I have meetings on my calendar older than the documented expiration date which I can still join.

@Steven Collier Hi Steven - sorry to resurrect a very old thread but I’m also interested in this although for Teams meetings rather than Skype.

 

Did you ever get an official answer?

 

Thanks

Richard

I've searched for 'Teams limits' in documentation and can't find anything similar to the S4B doc that states how/when expiration works.

 

Anyone else find anything?

 

Thanks
