Hi Lisa,
As you mentioned that multiple user can’t access workbook at the same time, may I know how you are sharing the Excel workbook?
Yes, you are about Microsoft Forms pro, it does not have a functionality of getting data from external sources yet.
If you are SharePoint online user, they you can store your workbook in SharePoint or OneDrive for business library and then share the workbook with other users to co-author.
Please note, to co-author a workbook, user must have:
- Users need an Office 365 subscription.
- One must have the latest version of Excel for Office 365 installed.
- Must sign in to Office with your subscription account.
- You need to use Excel Workbooks in .xlsx, .xlsm, or .xlsb file format. If your file isn’t in this format, open the file and then click File > Save As > Browse > Save as type. Change the format to Excel Workbook (*.xlsx). Please note that co-authoring does not support the Strict Open XML Spreadsheet format.
In addition, I would like to mention that there are few things which are not fully supported yet, such as if a user adds an ActiveX Controls, then other users collaborating the xlsm workbook at the same time might see the following message. To see new changes, you must click Reopen.
Thanks,
Neha
