Forcing users to use Online Mode in Outlook

Hey,

I am doing a migration of mail between tenancies on Office365. I want to avoid mass downloads of mails when i reconfigure outlook to new tenancy. The only way i see of doing this is to change all users to online mode and gradually change them back to cached mode. This will avoid bottleneck issues with download bandwidth.

IS there a way to force this change to Outlook via group policy ?

Download and install the ADMX files. You will find the setting under User configuration -> Administrative templates -> Microsoft Outlook -> Account settings -> Exchange -> Cached Exchange Mode -> Use cached exchange mode for new and existing Outlook profiles. Set it to disabled.

OK, then use the ADM files instead :)
Or just deploy the relevant reg keys directly:

HKEY_CURRENT_USER\Software\Policies\Microsoft\office\15.0\outlook\cached mode
 DWORD: enable
 Value: 0

Cheers Vasil,

The tool we use changes all profiles to cached mode by default so therefore whatever we prior to profile switch it will revert to cached mode. Therefore toying with the idea of getting users to restart machines once outlook profile has been configured. This is not an ideal solution. I'm racking my brains to find a solution to this issue. Which essentially is to avoid a bandwidth problem come morning after migration. At this stage we have 250 users with approx 500GB total of data about to come down the pipe Thursday morning !!! Ahhhh ! In heinsight, there is a lot i would have done differently, however we are where we are...... Any further ideas bar implementing online mode after profile has switched ?

If you were on 2013, the 'cache mail' slider would've been handy, as you can preconfigure it to download messages from the last 6 months only for example.

For 2010, you can play with the 'download headers' settings, and in general follow the advice in this article: http://technet.microsoft.com/en-us/library/cc179067(v=office.14).aspx
