Attempted operation is prohibited because it exceeds the list view threshold

Hello Mahesh,

Thanks for posting to the Migrator for Notes to SharePoint (MNSP) forum. I understand you are experiencing a "The attempted operation is prohibited because it exceeds the list view threshold." error when migrating with Migrator for Notes to SharePoint (MNSP). I have a few questions to better assist you:

1.) What is the exact version of MNSP you are currently using (Help | About)?

2.) Are you migrating to an on-premise SharePoint server, or SharePoint Online?

3.) Are you migrating to a new list, or does the list contain existing data?

Regards,

Hello Mahesh,

Just to confirm, does the SharePoint list already contain existing data, or is MNSP migrating to a new (empty) list?

Hi Trevor, 

SharePoint list contains existing data .For Empty list I don't have an Issue .

We have 13783 records and almost 90 columns .

Let me know if yo need more details to investigate the issue .

Mahesh

Hello Mahesh,

Thanks for the update and additional information. To clarify, are you stating that there are 13783 list items with 90 columns in the existing SharePoint list?

How many records are in the Notes application that you are trying to migrate to this existing SharePoint list?

You mentioned that you created an index using the Title column, I am not sure that this would be sufficient to workaround this SharePoint list view threshold. The following Microsoft KB article provides steps to create an index to workaround this issue and provides a list of suggested indexing column types at the bottom of the page:

https://support.microsoft.com/en-us/office/add-an-index-to-a-list-or-library-column-f3f00554-b7dc-44d1-a2ed-d477eac463b0

This Microsoft KB article also provides additional information about managing large SharePoint lists and libraries:

https://support.microsoft.com/en-us/office/manage-large-lists-and-libraries-b8588dae-9387-48c2-9248-c24122f07c59

However, in the end, you may find it better to create a new list in SharePoint Online for the Notes data, as adding to an already large list is likely to get more complicated as the list continues to grow.
