I used to have most of my users on PST files for local email archiving, however, I'm now getting a lot of staff using iOS and Android devices quite heavily for work (sales).
How can I store their emails? I'm looking for any suggestions, all welcome, even if they come with some caveats.
Now, I know there are more (much more) than a few Exchange archiving software options out there, that's one route, but are there any apps for local archiving on their devices?
I know an app would be pretty, but I have no legal requirement to keep the email - I'm really just trying to facillitate the needs of a small (but very vocal) group. It needs to be in a format that could, if needed, outlive the device if/when it's retired.
For ref, I'm running one Exchange server on a Windows Server 2008 R2 machine to serve about 19 email users.
