Recently we upgraded Exchange 2010 RTM to Exchange 2010 SP1 and since after the reboot users started to complain that their IPhone are unable to download emails. The emails get listed in phone but when one tries to open them gets the following error.
This message has not been downloaded from the server
I checked the exchange server and event id 4999 was logged repeatedly in Application log
Watson report about to be sent for process id: 1234, with parameters: E12, c-RTL-AMD64, 14.01.0218.011, AirSync, MSExchange ActiveSync, Microsoft.Exchange.Data.Storage.InboundConversionOptions.CheckImceaDomain, UnexpectedCondition:ArgumentException, 4321, 14.01.0218.015.
The most noticable part in this even is the work CheckmceaDomain, The point the issue is towards the default domain or accepted domains in exchange.I researched further with this error to find that there some issue with the Accepted Domains on the server. It’s a good time to inform that this exchange Server was part of a domain which started with SBS 2011 server because of which the Accepted domain has been defined with the name “Windows SBS External Domain”. Refer the screenshot below
Exchange 2010 SP1 has some issues with the Spaces in the name of Accepted domain, in this case “Windows SBS External Domain”. To resolve the issue we executed following CmdLet on Exchange Management Shell
1) List the Accepted Domain on Exchange Server
2) Copy the Identity of the Accepted domain whose name has Spaces in this case “Windows SBS External Domain” and change its name to without spaces using the following CmdLet
3) Reboot the server.
Hope this solution helps you to get over the issue in hand, Feel free to report new issues on our forum
