Grrr...this is so frustating...more meeting requests, agenda to follow. Then days later a separate email with agenda attached, instead of attaching the agenda to the original meeting request and sending it as an update.
I always, if not already done, attach agendas to my boss's meeting requests. That way when the reminder pops up, you can print any attachments housed therein, and you don't have to go searching for an email with an attachment.
Surely it's common sense
