This meeting may have expired, or it's possible you're using a bad URL

Issue: Unable to join meeting. 

Error message:
We're having trouble getting you into the meeting. 

This meeting may have expired, or it's possible you're using a bad URL. If the latter, try calling into the meeting using the phone number on the invite, or ask the organizer to drag you into the meeting from the Contacts list.
Problem Statement:
Skype for Business or Lync meeting is by default expire after 14 days. Schedule reoccurring meeting if you want to use more than 15 days. Normal meetings gets expire after 15 days hence reschedule new meeting if your meeting is expired.  If reoccurring meeting get expired, it may happen because user may create a conference, but gets the old conference URL. Not sure how it happen L  

For workaround refer:

You can check meeting configuration using below command let: Get-CsMeetingConfiguration  

If your meeting is older than 14 days and not reoccurring meeting then your meeting may expired.

Schedule new and use. If reoccurring meeting getting expired then follow below steps:
These steps basically reset your meeting conference ID and meeting URL.  

1.     Log on to Dialin simple URL. E.g. and login.

2.     On Dialin page, under assigned conference information:

Click on “Reset my Assigned Conference information

           3.     Click on “Yes” to reset your conference information.

4.     Now you will see new conference ID and meeting URL. Later you can schedule meeting and see if your reoccurring conference meeting is expiring.


Thanks you.
