There's a quiet frustration in this user's question, and it's one we understand deeply. When you copy a worksheet in Excel, you expect a faithful duplicate, print area included. Instead, this person gets a copy that quietly shifts its print boundaries, losing rows between 58 and 63. The fact that it only happens in one Microsoft 365 account, while another account handles the same steps correctly, points to something specific and personal, not a universal Excel quirk. Our take is simple: this is not a mystery without a solution, and it's not a reason to abandon the tool. It's a signal that your environment, not your skill, needs attention.
What stands out here is the precision of the report. The user isn't guessing. They've isolated the variable to their own account, tested the same workflow elsewhere, and confirmed the discrepancy. That's the right instinct. The print area difference, five rows in this case, is too consistent to be random. It smells like a stored setting, likely tied to the workbook's page setup metadata or a default print range that follows the account's profile. When you copy a sheet, Excel carries over certain layout properties, and if your account has a lingering custom setting, like a defined print area name or a page break override, it can reapply itself during the copy. The other account doesn't have that baggage, so it copies clean.
The practical takeaway for anyone reading this is to stop treating the copy function as a black box. Before you copy, check the original sheet's Page Setup, specifically the Print Area box under the Page Layout tab. Clear it if you don't need it, then recopy. Also, look at the View tab for Page Break Preview. Sometimes manual page breaks, even ones you didn't intend to set, persist invisibly and influence what prints. If those are clean, the next suspect is the account-level default. Try resetting Excel's advanced settings to their baseline, or run a repair on your Office installation. None of this is glamorous, but it's effective.
The user's suspicion that they changed something by accident is probably right, but that's not a failure. It's a clue. The fix won't come from blaming yourself or the software. It will come from methodically isolating which setting travels with the account. And here's the concrete point: if you replicate their test and see the same drift, don't just accept it. Open the copied sheet, go to Page Layout, and check if a print area is defined. If it is, clear it and set your own. That single step will tell you more than any forum thread. Your data deserves a copy that respects your boundaries, and with a little digging, you can make sure it does.
