Quick update before the Christmas break. We are right now in the process of releasing GW7 Interim Release 1. It's a public patch, fully tested and it is a precursor to SP2. It will appear on the GW patches page later today. Now, if rolling out patches takes your company a while, or your problem is not listed in the readme then I should warn you that we plan to follow with SP2 some time in the first quarter of next year - bear that in mind. And no, I am not going to give you a date - it has backfired on me every single time :)
Also, available for download are a MAPI beta and the GW7 Migration Utilitity for MS Exchange. The MAPI beta contains a load of fixes and enhancements for our MAPI provider. So if you are experiencing problems with utilities that use MAPI to send mails through GW then go and give this a try.
The Exchange Migration Utility is the result of months of work for our team and offers vast, vast performance increases over the old version. If you are planning a migration soon then make sure you give it a try - it's free after all. They are all available from here. Make sure you select the beta link at the top for the 2 beta updates.
