The ultimate list of useful links for IT professionalsYou're well in to the evening and the 'simple' site visit you embarked upon has turned in to a monster can of worms. Turning it off and on again repeatedly has failed and you've been watching status bars for the best part of the day with no hope of seeing home any time soon. What you'll take away from this three part series of useful links to free utilities and indispensable articles, may just provide that lifeline in such a situation. Back by popular demand, behold part two of our ultimate list, compiled by IT professionals from across the UK.

If your business closes over the holiday period, and you're 100% confident your data won't be changing while you're away, it's quite likely that you'd rather be eating, drinking and being merry than disappearing off to needlessly change a USB hard drive. A little-known feature of BackupAssist may just ensure your home remains harmonious this festive period. The scheduling calendar makes it simple to prevent a backup from running on a specific day(s), and here's how you use it.

Scientifically proven to solve precisely 99.3% of all technical problems faced by modern civilisation, your ability to "turn it off and on again" is perhaps the most powerful weapon you have in your arsenal as a seasoned IT professional. It's important to be realistic however, and, at some point it is I'm afraid, quite likely you'll be required to go beyond the call of duty. Of course you should always try pumping the on/off button of affected hardware hysterically to be absolutely certain the geek magic has transferred but failing that you should ready yourself for tough times ahead. Yes, you may well need to 'Google', to diagnose symptoms and worse still, troubleshoot with your brain. In extreme cases, you should be warned, it's not unheard of that the more demanding customers may ask that you plan to prevent the problem from happening again. Pooled from thousands of IT professionals around the globe, the following software utlities, web services and how-to guides will help you be prepared should the unthinkable strike.

Our installation guide for MDaemon users details how to get MailStore up and running using a combination of two archiving jobs (journalling and mailbox). That works really well if you want to archive everyone's mail, but sometimes I'm asked about archiving for a handful of users only. Fortunately MDaemon uses a highly customisable content filter to journal mail which means it's flexible enough to make this possible...here's how I suggest you go about it...

UPDATE: 10/12/13 Google released Android 4.4.2 today and I can confirm that this now fixes the Exchange sync issue on my Nexus 5. See below for more details... A couple of us in the office have just taken delivery of some shiny new Nexus 5's - fantastic devices we're really happy with but we've unfortunately both come across what looks to be a known issue setting up the ActiveSync connection to synchronise them with MDaemon Messaging Server. MDaemon has an integrated ActiveSync server but this issue with the devices will also apply to those of you who use Microsoft Exchange.

BackupAssist announcementIn the latest version of BackupAssist (7.3.1), there was a change to the activation process I'd like to make you aware of as it's understandably catching a few customers out. In the latest version there was a change implemented to help ensure that as a customer you're on the 'local' build of the software, complete with support links that point back to our technical team here in the UK.

BackupAssist Technical Support InsightWe often get support queries where the PC clock has been the cause of an issue but never have I seen a few minutes of drift make such a difference. This one isn't actually specific to BackupAssist but it did rear its head with a customer who happened to be storing their backups on a local NAS. The backup job in question was a 'file protection' one, so the simple backup of files to a local network share as a destination. The job had run fine for many days without errors but suddenly overnight the job would fail with an error like the one below:-

Create a disposable email address using MDaemonI recently stumbled across this post about Outlook.com accounts which talks about being able to give out a temporary valid email address, without having to reveal your main account - something you can also do in MDaemon Messaging Server. The 'sub-addressing' feature in MDaemon has been around for years but it's one of those that's often overlooked because it's a little buried in the account options section.
