You can say this all the time but without thinking that it is part of the Sunnah or that it is something recommended to say before a meeting or something similar. It is just praising Allah and seeking refuge from Satan

And Allah knows best

When can I say this duah? “As Salaam ‘Alaykum wa Rahmatullaahi wa Barakaatuh, lnna il-hamdulillaah, Was-Salaatu Was-Salaamu ‘Alaarasoolillaah, Authubillah Minash-Sheatanirrajeem Bissmillahi Rahmani Raheem,”
