First of all apologies for the negativity of this post but I'm fed up and am looking for some sort of positive feedback to convince me Scalix is still the way to go.
We have been a Scalix Enterprise house for around three years now and in that time have had something of a rough ride both with the product and the people who are meant to be supporting us. We've ben running in production since 9.4 and are now on 11.4 and in that period of time have experienced everything from great support, in the 9.4 days when we had an account that had been accidentally deleted and would restore, to diabolical support, a request for information which we logged with regards to omcontain which took 3 months to get a response, the response was that they have no information but we've chrged your support account anyways. And in the middle we had a reseller for support, who effectively sulked each time we logged a call as we wanted them to investigate and resolve the issue rather than just randomly poke around.
As for the product promises of new features seem to come and go, mostly not materialise and when they do they're a fraction of the promised feature. iCal support comes to mind. Sorry guys but you can't claim iCal support when you have to delete and recreate the profiles in iCal once a month due to incompatibilities between the two and god forbid you should date touch the calendar it screw up your entire email account so it can't be accessed through outlook and crashes and users outlook when they try to book you for a meeting.
Finally NotifyLink. I'm in the process of trialling this at the moment and honestly I'm under impressed. The documentation if you wish to set it up yourself is very poor. The hosted service took nearly two weeks to setup by notifylinks partner, it doesn't sync contacts or tasks, which is 50% of what the integration is meant to do. To top this all off I use a BB 8800 and on that the battery runs down 50% quicker and the email push requires an additional app which doesn't display on the front page or notify you on the screen if you have new emails.
Unfortunately the two choices are exchange and scalix as I see it. Pretty much the only thing keeping with Scalix at the moment is my comfort in the fact I know how good our backup strategy is, something I could never claim of Exchange and the pain and agony I would have to go through to move everyone to Exchange.
