Does anybody know how to rename 'More Addresses' in Account and Contact entities navigation pane?
The usual method would be to change the display options in the address/contact or account relationship, but this is read only in this case.
There is an easier way as well... go to Settings -> Customizations go to the account entity and select "Messages" from the menu left. There you can find "more addresses". open this line and change the display name. Save + publish. Done :-) Hope this helps.
