Throttling limit is exceeded by the operation

Getting the error "Throttling limit is exceeded by the operation" when opening the document link of CRM online entity which is integrated with "SharePoint online".

My document library mapped here in CRM online contains all items more than 5000, but at top level it is having 100 + folders.

It seems that the error bcoz of threshold limit of list which is 5000.

Is there any workaround for this.

Any help is appreciated.

Thanks,

Raj
