Office 2013 Error when connecting to O365 cloud

The office pro plus 2013  outlook client 15.0.04701.1000 32 bit version is displaying an error when troubleshooting to O365 cloud. " The Microsoft exchange administrator has made a change that requires you quit and restart outlook" - we see this error and think there is an issue with the backend mail db being moved as some tech notes display this for exchange 2013. The outlook 2013 client can open the mail db if you do it manually. We tried to upgrade to the latest fp for this did not resolve it, the only work around is to downgrade to Office 2010 sp2 - enclosed is the technote on the difference type of connection using 2013 vs 2010 way (RPC over HTTP) - its something to do with the connection and the endpoint.

Messaging Application Programming Interface (MAPI) over HTTP is a new transport protocol implemented in Microsoft Exchange Server 2013 Service Pack 1 (SP1). MAPI over HTTP improves the reliability and stability of the Outlook and Exchange connections by moving the transport layer to the industry-standard HTTP model. This allows a higher level of visibility of transport errors and enhanced recoverability. Additional functionality includes support for an explicit pause-and-resume function. This enables supported clients to change networks or resume from hibernation while maintaining the same server context.

Implementing MAPI over HTTP does not mean that it is the only protocol that can be used for Outlook to access Exchange. Outlook clients that are not MAPI over HTTP capable can still use Outlook Anywhere (RPC over HTTP) to access Exchange through a MAPI-enabled Client Access server.

The question is does anyone have this same issue starting this past 3 weeks with O365? If so what is the fix in the registry as I can only find technotes for this such scenario on exchange 2013 on premise setup.

I need outlook 2013 to connect and not have to downgrade to outlook 2010?

The error you are posting, normally seen when you move a mailbox. I suggest you to contact Office 365 support. What happened when you are trying to connect via OWA.

It has to do with the latest version of outlook 2013 - downgrading to outlook 2010 solves this issue
