So at the office a lot of us are using IOS devices to run our exchange activesync email. We notice under 8.02 the "Mail Days to Sync" maxes out at one month. This used to have a "No Limit" option. I talked with the chief engineer a few minutes ago regarding our email server in case there is a limit being enforced but there isn't. I talked with one of our end users who was running an IOS 7.x email client on their iPad and that was still getting email as old as June of last year. So if you have an IOS device and update to 8.x just watch out - you might lost your ability to retain as much email as you need. Particularly difficult for one user who flew on a plane to Florida to deal with a family members funeral and some of the emails she needs are beyond one month old and not in her contacts and she didn't bring her pc. I suggested an alternate solution for her but this is kind of a problem.
