The subscription mails that i am receiving from Power BI is only partial i.e. image of the total report and places like tables where there requires a scroll cannot be used and we have to again open the report on the power bi portal to read the same.
Once you’re subscribed, Power BI will regularly send screenshots of that report page directly to your inbox whenever the data changes. The image in your inbox will show up exactly as it does in Power BI, and include a link to the report where you can drill into any interesting findings.
So scolling in the email report is not supported.
