Based on what you’ve shared in your follow‑up, this may be related to a Teams Free meeting chat and recording sync issue within that recurring meeting series, rather than a OneDrive storage problem.
The message “Sorry, chat is unavailable until you join the meeting” is often a sign that the meeting chat for that particular occurrence hasn’t fully transitioned into its normal post‑meeting state. When that happens, the chat and any associated recording may not become available as expected.
For Teams Free (personal accounts), meeting recordings are typically stored in Microsoft’s cloud for a limited period (usually up to 30 days) and aren’t saved to a OneDrive > Recordings folder, so not seeing anything there would be consistent with this setup.
If you haven’t already, it may be worth trying a few simple checks, such as signing out of Teams on all devices, clearing the Teams cache, and then checking again a bit later in case the chat or recording is still syncing. In some situations, if a recording upload doesn’t complete successfully, Teams will normally show a recording message in the meeting chat allowing the organizer to retry or download it. If there’s no recording entry in the chat and it’s also missing from your Teams data export, user‑side recovery options can be quite limited.
At that point, Microsoft support would be the best next step to confirm whether anything is still available on the backend. When contacting them, it can help to mention the affected meeting dates, confirm that this was a recurring Teams Free meeting, and include the exact error message you’re seeing. For future meetings, creating a new meeting series and doing a short test recording first may also help avoid a repeat of this issue.
I know this isn’t the outcome you were hoping for, but I hope the explanation helps clarify what may have happened here. If you decide to reach out to Microsoft support, they’ll be best positioned to confirm whether anything is still available on the backend. Please feel free to follow up if you have any questions along the way.
