@aanandkarki, Did you figure out this issue? We're having the exact same one as you.

It seems the meeting was created before migration. However, I am not sure if this will work, but you can try Meeting update Tool :https://support.office.com/en-us/article/Meeting-Update-Tool-for-Skype-for-Business-and-Lync-2b525fe...

Nope I could not find the root cause but as a work around, I have removed the groups from the Meeting requests and cleared the cache and then resolved the name directly from GAL and sent the updated/modified request which fixed the issue.
I think it has something to do with DL membership caching.

Hello @aanandkarki ,
This issue occurs if the Clutter feature is enabled for the user but the Clutter folder is missing in the user’s mailbox.
To work around this issue, turn off Clutter for the user. To do this, use one of the following methods.
Connect to Exchange Online by using PowerShell.
Run the following command:
Get-Mailbox user@contoso.com | Set-Clutter -Enable $false
Thanks,
Manu
