"fetch new data" greyed out in iPhone Exchange mail settings

The the Fetch New Data section in my iPhone is all greyed out.
Would "cached mode" for Exchange 2010 be the blame for this? Or would it be a local iphone setting?

Cached-mode shouldn't be affecting your mobile mail. Check to see if device restrictions are enabled under Settings>General>Restrictions.

if they are, the setting that would grey-out "fetch new data" is the "allow changes>Accounts>On or Off

Ok thanks. Yeah I figured Cached mode wouldn't be affecting that...that's only for Outlook client, right? and is a user/computer GPO?
Matt MinorTechnical Systems AnalystCommented:
Correct - Cached mode is basically a buffer for clients when communicating between the Exchange server and Outlook client. It is designed to provide a more "seamless" experience for the user.

Cached mode can be set via GPO yes, but it can also be enabled locally should the need/desire arise.

Ok thnks and do you btw know if cached mode affects things like Outlook features such as adding senders as Junk or safe or blocked, in Outlook or OWA
Matt MinorTechnical Systems AnalystCommented:
No it would not have any relationship to those settings. The only thing (not the ONLY thing, but the only frequent/most-noticeable thing...)that cached-mode will cause issues with is mail-sync and global-address-list synchronization. Changes don't become live immediately as there is that "buffer" I mentioned earlier, so sometimes it creates a bit of a troubleshooting problem for unsuspecting users. Other than that, the rules/safe-senders etc would not be impacted by caching.

Ok well I check and Restrictions is set to off wondering what else I can check.
There's a MobileIron MDM thing I wonder if that's on there and is messing those settings
Matt MinorTechnical Systems AnalystCommented:
Ah most likely. Check with your corporate mobile device administrator for MDM policies.

Awesome man thanks so much. It looks like it was just a power issue on the phone, something about power saving mode.
