I'm working on an iOS app that is supposed to read and send mails. For accessing inbox folder I've used the "INBOX". It worked well for Yahoo and AOL but not Gmail. Someone told me to try "[Gmail]" , "[Gmail]/All Mails", "Gmail/[All Mails]". I've tried all of these but none of them is working. And importantly if I write "[Gmail]/Spam" or "[Gmail]/Trash" it works fine. So the point is that I can access mails of all folders except inbox. How can I access gmail's inbox folder?
Solved the issue with
"[Gmail]/All Mail"
