Can't upload multiple files to SharePoint Server 2007 document library anymore

Hi @Tevon ,

Unfortunately, SharePoint server 2007 is no longer supported. Based on your description, I found this article for your reference.

Workaround In the Document Library, under Library Tools click on Datasheet View, then click on Standard View. The Upload Multiple Documents command should now be enabled. This will enable the command only for the Internet Explorer session. If you close Internet Explorer the next time you access the site from that same computer you will need to click on Datasheet View and Standard View again. Resolution The farm administrator needs to change the Web Application's General Setting Enable additional actions and Online Status for members to Yes. Open the Central Administration page Click on Manage web applications Select the web application you would like to configure From the ribbon select General Settings. In the section titled Person Name Actions and Presence Settings change the setting Enable additional actions and Online Status for members to Yes. Click OK to apply changes. Clear the Temporary Internet Files on the client workstations, close all Internet Explorer windows, open a new Internet Explorer window, access the document library again and look for the Upload Multiple Documents command under the Documents tab in the ribbon.

Hope this is helpful.
