Due to a corporate design guideline, the font used in emails needs to be changed.
This is not a problem.
However, the text and rich text signatures cannot be adjusted to the font.
They are always inserted in the default sans serif font.
Unfortunately this can only be solved by modifying the “CoreEmailClasses“ Lotusscript library and probably the (CalendarProfile) form as well.
You can only do this by creating a customized Mail template.
But be warned: If you have any mail related problem later you will have to revert to the default template because support at first will always blame your custom template for any problem occuring in that context.
You have to modify the code in “UIMemoDocument” class and there “InsertSignature” method.
There are multiple different places to modify depending on the options that you select in Calendarprofile.
And if you select “Rich Text | 3“ as an option for SignatureOption- field in calendarprofile then it will be even more complicated.
As an experienced developer this is feasible but not easy.
