The other day I was on the way to a potluck with some new friends and I was running late (somehow I always underestimate how long cooking really takes). On my way over I remembered that the location had changed earlier that week and I didn’t actually know where I was going. Checking my email I found that I had deleted the part of the thread with the critical information and only had the emails about what everyone was bringing.
Admittedly that wasn’t very bright of me, but thankfully I had email server search on my phone. From my inbox I used Menu -> Tools -> Search Server and then searched for “potluck” in all folders. It found the email for me and I was able to get to the right place without having to call anyone and admit my mistake. Check it out – it’s a helpful feature, especially when you don’t know where you are going
