I need to be able to access the same Exchange mailbox (hosted on Exchange 2003) on separate PCs - some running XP with Outlook 2003, others Vista 32sp1 with Outlook 2007 - and potentially a Mac with OSX 10.5.6 running Entourage 08.
Is there a view on whether this can/can't be done? Any known issues / gotchas to be aware of? I'm thinking specifically here about the way flags and colour coding of categories and messages are handled differently between the two Outlook versions..
The different Outlook clients are likely to have the mailbox open simultaneously.
