I have read where the NGSC has the capability to sync only one Personal OneDrive but multiple Business OneDrives. I have mine set up to sync my Business OneDrive and it works great. When I attempt to sync another Business OneDrive by using the Sync button on the web it causes my OneDrive to crash and I have to set up my business OneDrive again. Anyone experienced this or have any suggestions?

so there are 3 different things:1) Access to SharePoint Online and Admin Centerwe have had the Registry Key in the path, and now this works different.Look here for this Blog post: Next Generation Sync Client | Registry key vs Admin-Center 2) The Shared with me issue:Look for this Blog post: OneDrive for Business | Local Sync of ‘Shared with me’ files 3) The Next Generation Sync client and multiple tenantsSo you may syncOne OneDrive (Personal)One or more OneDrive for BusinessOne or more Share with me (with the restiction: Must be in a folder) so for the second tenant, as described: Add account (you must have the credentials). Then you may select which folder you want to have sync to your local machine. For Groups or teamsites you have to go to the group via Web-Browser (Edge, Chrom) , go to the library, press the sync button and choose the NGSC client and not Groove!!. If somebody have shared you to a folder, the same behavior.

Try going to the settings of your onedrive and using the add account. Sign in with your second onedrive for business account. Afterwards you should be able to sync SharePoint DLs from either accounts. I havent used the sync button on the web. But I know the above way works.

That does work...thanks. Not necessarily the solution I was looking for. I I have access to folders in Someone else's onedrive via a share can I not use the NGSC to sync those?

Yes. You should be able to. Go to the share through the web and you can use the sync button. With two different domains you will basically end up seeing 4 areas in file explorer. 2 x for onedrive (each domain). 2 x for SharePoint Libraries, shared folders (for each domain). Now it may be an issue with the browser. Ive been using Edge and it works fine. Also I am on client 17.3.6816.0313 (from the creators update). Though i had it working on some older clients as well (previous version without creators update). One of the biggest issues i face myself (and with several others) is the perpetual sync arrows on the icon that appears until a restart of the client. Or the uncertainty from the constant "processing changes" that crops up from time to time.

DeletedIf I understand well, you are asking to sync, with NGSC, the folders that have been shared with you. This is a definitely supported scenario.Go to "Shared with me" in the ODfB web UI, click on the shared folder and then, when you are inside the folder, on the sync button in the action bar.Be aware that you can't sync single files, though, but only folders. Also, be sure that the option to sync with the new client has been selected in settings.Hope it helps...

No diagnostic available from here : No OS, NO Version of the NGSC available.
So to check it on those 2 devices, use SARA (Microsoft Support and Recovery Assistant for Office 365) to check these devices..
Another method: New device, set it up with one of these accounts

If Checks do not find anything, open a ticket with Microsoft
