iPhone, OWA Premium and POP3/IMAP4 issues with Exchange 2010 SP1

After applying E2010 SP1 iPhone users may not be able to view the content of incoming messages in their Inboxes, and when they try to open a message, they get an error that this message has not been downloaded from the server.

Also OWA Premium users may not be able to reply or forward a message. They may see the following error in OWA:

‘An unexpected error occurred and your request couldn’t be handled. Exception type: System.ArgumentException, Exception message: imceaDomain must be a valid domain name.’

And POP3/IMAP4 users may also not be able to retrieve incoming mail.

The issues are caused by non-standard domain names. Verify that there is one domain marked as ‘Default’ and it’s DomainName and Name values are valid domain names, and e.g. don’t have a space within the domain name.
