We have just started with Office 365 Hosted Exchange.


messages from other domains as well s our own domain (@siatgroup.com.au) are not getting to my mailbox (Junk mail folders are empty and junk settings are set not to delete).  We need this addressed urgently as it is affecting internal as well as external work flows.


I.E a message today from davidh@siatgroup.com.au to jade@siatgroup.com.au had not arrived after 2hrs and no delivery failure message was received either.
