Hi @Dakin, Jennifer
As far as I know, the Meeting URL never expires and expires only in relation to any PSTN dial-in numbers, CVI coordinates, and/or underlying conferencing policies and settings. Even if the meeting invitation time has passed, you can still join the meeting through the previous link.
To extend a recurring meeting without losing your records, you can only update the original meeting time in Teams or Outlook calendar. The two are synchronous and only one needs to be updated.
Update meeting time steps from Teams:
Go to Teams calendar> right-click and select Edit > Update Meeting Time> Send Update.
To update meeting time steps from Outlook:
Outlook Calendar > right-click and select Open Series> Update Meeting Time > Send Update.
