Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,
I just want to add that this is just a Read Only feature that was embedded on the picture by the program that created it and it is not easy to remove just by selecting Save As.
After or before editing(which ever works for you),
Click File
Select Save As
Click On Tools drop-down chevron
Select Properties
Uncheck the read-only check box and click OK
Confirm Attribute Change comes up, Apply Changes
Click OK
Click Save
Hope it helps.
