Dear Danielle McKinstry
Good day! Thank you for posting in Microsoft Community. We are happy to help you.
First, for your concerns about the In channels section and In site library section in SharePoint Document Library connected to Teams.
We'd like to share with you following information:
In Teams, we can have Public Channels and Private Channels. Users added into the Teams become members in all Public Channels by default. While we can only choose members from the Teams to be member of Private Channels.
The difference between the In channels section and In site library section are following:
In channels section contains all channels folders including Public Channels and Private Channels. Note: if a user is not added as a member of Private Channel, he won't be able to see the Private Channel folder in the In channels section.
In site library sections contains all Public Channels folders but not Private Channels folders. And it also contains all folders/files created from the SharePoint site, for example, folders/files created with "+New" from ribbon will show in In site library section.
So all members in the Teams can access the In channels section, but only member who is in the private channel can see Private Channel folder.
This change in SharePoint document library is used to distinguish folders that are related to channels in Teams and folders that are created from SharePoint site itself.
Second, you mentioned when you try to resync the document libraries from One Drive, you will got the error message, to help us narrow down the behavior and have a further investigate, we want to confirm some information with you:
- Did click the message to check if the file is in the OneDrive folder?
- Please try to create a new OneDrive folder then sync the file to the new folder to check the behavior.
- May I know does all files have this sync behavior or only the specific one have?
- Does other users in this Team have the same sync query when they sync the document libraries from One Drive?
- How did you sync the library? Go to the library and then click Sync button or other way?
We’re looking forward to your reply and will continue to help you all the time! If there are any misunderstanding or unclear, you can post back in your free time.
Your understanding and patience will be highly appreciated. I hope that you are keeping safe and well!
Sincerely,
