EAS Proxy Change Email Server

Hello

Looking to see if this is possible and hoping I'm just missing something...

We us the EAS Proxy Standalone currently configured to all email access to our internal Exchange Server. We are moving to Office 365 and would like to keep using the EAS Proxy to control device access to Office 365 email.

I updated the current configuration of the EAS Proxy to point to Outlook.Office365.com and it doesn't want to "re-point" the users to O365, still is communicating with our internal Exchange Server.

Is there a caching issue that needs to be cleared or is this configuration not going to work and I'm going to be stuck having to reconfigure all mobile phones by deleting and re-adding the profile back?

I hope that makes sense. Just want to update the EASY Proxy without impacting all mobile devices using that EAS Proxy.

 

Thanks

Jeremy
