Hi @sudheermadduru,
Do you want to drop the attachments of a single email or multiple emails into your SharePoint library?
Does the received email have a unique subject?
If you want to drop the attachments of a single email into your SharePoint library on every Monday Morning 10 AM, I think the "Recurrence" trigger could achieve your needs, I have made a test on my side and please take a try with the following workaround:
- Add a Recurrence trigger, Interval set to 1 and Frequency set to Week. On these days set to Monday and At these hours set to 10.
- Add a "When a new email arrives" trigger, Has Attachment field and Include Attachments are both set to Yes.
- Add a "Apply to each" action, input parameter set to value dynamic content of the "When a new email arrives" trigger. Within "Apply to each" action, add a "Apply to each 2" action, input parameter set to Attachments dynamic content of the "When a new email arrives" trigger. Within "Apply to each 2" action, add a "Create file" action, specify Site Address and Folder Path. File Name field set to Name dynamic content of the "When a new email arrives" trigger, File Content field set to Content dynamic content of the "When a new email arrives" trigger.

The flow works successfully as below:
Note: The above solution that I provided would only be triggered once on every Monday morning 10 AM, because the Recurrence trigger would only be fired once on every Monday Morning 10 AM.
If you want to drop the attachments of multiple emails into your SharePoint library on every Monday Morning 10 AM using the "Save my email attachments to a Sharepoint document library" built-in template, I afraid that there is no way to achieve your needs currently in Microsoft Flow.
Best regards,
Kris
