A meeting was created from a shared calendar, and then forwarded to a couple distribution groups with about 40 members total, as well as a few individuals. These members then forwarded this meeting to very large distribution groups. In the original invite, it now shows each recipient individually alongside each distribution group. The owner of this meeting needs to make a change and send an update, but now that it shows the recipients as individuals instead of in distribution groups, they receive a "too many recipients" message. Short of creating a new meeting, are there any options here?
