At my job we tend to give mishloach manos to each other before or after Purim, since we’re not here on Purim. May I participate in this? I know from your previous response that I may only give to 1, 2 or 3 people on Purim. Thank you.
On Purim itself that you have the obligation to give mishloach manos, you are allowed to give some simple presents to a few people, but before or after Purim it is like any other day of the year and you should not give or receive presents.
