Missing Random Exchange Folders

Good morning everyone,

I sincerely apologize if this has been posted but I tried to search for an issue similar to this and was unable to find one. If you all have some searching tips for me, I'd greatly appreciate it so I don't clutter this site with repetitive questions! Anyways, I've got a Nexus4 and I seem to be missing random mail folders. All the folders have some kind of mail in them and the messages in these folders are semi-recent. Is there a setting I'm forgetting or is there something I'm not doing correctly? All help is welcome and very much appreciated. Thanks in advance for all of your time! ;)

what email are you using? gmail? in the imap setting there will be an option to display folders. you have to enable it on web for IMAP.
only then it will showup

Open the mail account, tap Menu -> Settings -> Days to Sync. If the setting is, for example, 3 days, you will not see any folders where the most recent mail is 4 days or older.
