Would/Should you block linkedin to your Exchange Server? No comments yet

Apparently Linkedin now have a feature that allows users to provide their corporate passwords to a third party so the users can then send invites to other people in their office.  I really don’t see how this can Be A Good Thing 😉 – Paul Cunningham has a post on ExchangeServerPro on this feature and links to Adam Fowler’s post on how to block LinkedIn to Exchange. This is interesting as we’ve also seen this issue with Verizon doing something that we expect is screenscraping to provide email information to phones. Admittedly this was a while back but we have found it hitting the Exchange server so it will be interesting to see if this successfully blocks the server.

In a meantime, maybe it’s time to not only educate LinkedIn that this is a really bad idea but also your corporate users.

For what it’s worth the solution is to do the following:-

There are a few settings to check. First, under the Set-OrganizationConfig area, you’ll need to check that EwsApplicationAccessPolicy is set to ‘EnforceBlockList’. If it’s not, it’s going to be “EnforceAllowList” and you’re probably OK, as it’s using a whitelist for access to only what’s listed rather than a blacklist, to only block what’s listed.

Next, you need to add LinkedIn into the BlockList. This is done with the command “Set-OrganizationConfig -EwsBlockList LinkedInEWS

Fixed:Corrupt contacts in outlook but they appear ok on phone. No comments yet

Had a weird problem this morning with a user that had issues with incorrect data appearing in their outlook contacts. When you looked at the contacts in Outlook 2007, the Full Name was typically somebody else, yet the email address and name displayed in Outlook would be correct. Occasionally things like company name would appear incorrect. Looking at the phone, the data looked correct however the phone typically does not seem to use all of the fields that outlook2007 displays.
When I looked at the contacts within OWA the data looked ok. In OWA I changed the middle name on one of the corrupted contacts (although it looked correct in OWA) and then switched back to Outlook – the contact was now showing the middle name as expected, but the rest of the data was also coming across correctly. I took out the middle name within OWA and sure enough Outlook removed the middle name too and the contact was now correct.
The next stage was just to open the contact in OWA and hit save and close. This fixed the contact in Outlook too. I have no idea why this issue occured, and thankfully there are not *too* many contacts to open (only 170 in total) but just opening and then doing a Save and Close fixes the issue.
It will be interesting to see if this issue reoccurs.

Exchange 2007 services fail to start on DC (SBS server) No comments yet

I’ve had an issue with a new SBS2008 server, running Exchange service pack3 rollup 2 where the information store service does not start after a reboot, especially annoying after the server is rebooting with a scheduled maintenance task. Apparently this issue was fixed in service pack 1, roll up 5 but I’m still getting it 2 service packs and 2 rollups later.

Microsoft have a “fast publish” knowledge base article 940845  and the first solution is to start the services manually – really helpful!  Thankfully there are other solutions that involve changing the dependencies of the services to ensure Exchange does not try to start before AD has finished.

One word of warning – using the Microsoft KB to determine the latest service pack or rollup for Exchange 2007 returns Service Pack 3, rollup 1 from http://support.microsoft.com/kb/937052. However Rollup 2 has been available since Dec 14th 2010. I’ve put a note on the original kb article but the better way to determine the latest rollup is probably to search for Exchange 2007 service pack 3 rollup

Update Knowledge base 940845 now has a fixit file you can download that will change the dependencies for you along with instructions on how to fix it manually. The article no longer has references to this issue being fixed in previous rollups – probably because this was obviously not the case.

Cost for bulk uploading to Microsoft’s Exchange Hosted Archive No comments yet

As part of our investigations into hosting mail online using Microsoft Exchange Hosted services I have spent several hours on the phone with several companies to obtain prices and quotes. A couple of companies are out of the running as they didn’t bother to return my calls and although Microsoft were helpful, they just did not get it.
One of their offerings is email archiving. Every email sent and received, both internally and internally is copied to the archive service which is then searchable for ediscovery or just in case you can’t find that one email you know you received way back when. The only downside with this is the old email currently sitting on the exchange server that would not be searchable. However according to the Buy Microsoft Exchange hosted Services, “”You may bring historical data into the archive for a one-time charge, which is priced per GB”
As you can purchase the standard archive service from Microsoft and the same page contains prices for this service, it makes sense that Microsoft would be able to provide costs for this data import. About 2 hours on the phone later I realised that Microsoft unfortunately do not have a clue and nobody was able to give me a straight answer or even a ballpark figure. I was bounced around to several departments until eventually someone said that this service is purchased through the reseller channel. This doesn’t really make sense as the BPOS service itself can basically be purchased direct so why not the data import?
Our reseller is Ingram Micro, but their price list is only available to people with an account – useless for a tech like me who is trying to get some data together. However, CDW came to the rescue and this service is available by purchasing the “Microsoft Exchange Hosted Archive Historical Data Load at a cost of $60 per user (not per GB as in the original Microsoft documentation). The part number is 74P-00053. If you have an Enterprise Select agreement the part number is 74P-0059 but the price is still the same.

I’m not sure why Microsoft can’t give this price in the original web page and say to contact your normal reseller for more information.
Once the order has been placed there are more hoops to go through to get the data sent to Microsoft. The data can apparently be ftp’d to Microsoft – I’m hoping this is actually secure ftp – but as most users are going to have many Mb’s or Gb’s of data the normal scenario is to put the data onto a USB drive. I was pleased and also surprised to see they support Truecrypt. For more details of the process, continue to read the rest of the entry.

Fixed – ‘gtLV’ is null or not an object when replying to an email from OWA No comments yet

I was getting the “‘gtLV’ is null or not an object” message when I replied to an email using our Microsoft Online Hosted Exchange email account. Ironically enough, the problem would always occur when I replied to a new email from a Microsoft support engineer. The email would go through but I would get the ” ‘gtLV’ is null or not an object” error message popup on the screen. If I replied to the email again the problem would not occur. A very similar message can be seen in the Microsoft Exchange Server forums where I also posted the provided solution.

After many emails to the very patient support tech at Microsoft (as I would reply and then send an email to let him know if the reply worked or not) we escalated the ticket and I got back the following resolution.

1. type regedit on command prompt or run
2. go to: HKCU\Software\Microsoft\Internet Explorer\Main
3. create TabProcGrowth (string or dword) and set the value to 0

This solution worked for me.  From what I can see at the ie8blog this has the side effect of reducing the protectedmode protection and I think the browser tabs use the same process rather than running in seperate processes.  This is a slight downside, but I doubt many users will care – they’re more than happy to have OWA working.

Office 2010 almost here… No comments yet

I’m running the Office2010 beta at home (mainly for Outlook and OneNote2010)  and would highly recommend it when it is finally released. If you are running Exchange2010 then there are even more reasons why you should be running Outlook2010. (Note that a lot of the extra features such as mailtips and access to the archive mailbox are already available with the outlook web access app). If you purchase and activate Office 2007 between now and Sept 30 2010, you will be able to upgrade to 2010 via a free download. You will need a LiveID, the receipt and to register your purchase. More details available at the Office2010 Technology guarantee website.

Exchange2010 training from Microsoft No comments yet

It’s a busy week at the office this week as I’m at a 3 day event on Exchange2010 training as part of Microsoft’s Ignite sessions. You do need to be a Microsoft Partner to register for the Exchange 2010 training (if there are any further events going on – I’m not sure) but if you are going to be using or supporting Exchange2010 then I highly recommend it. So far it seems to be very similar to the Exchange admin training courses you would normally attend, but at a fraction of the cost. It’s a level 300 course so pretty technical – by about 4pm on the first day my mind was starting to get a bit confused – there was a lot of theory today and you certainly need to have some familiarity with previous versions of exchange.

The neat thing was that we’ve just recently moved to Exchange2010 in-house, so I was able to check some of the features that I didn’t already know about on our live client (outlook or outlook web app) as we progressed through the training.

We’re using Windows2008 machines running Hyper-V with 8gb of memory which means some creative juggling of memory and sometimes the machines are slow, but it really is the only way to do the training. Some points we have 4 machines running – this would have been almost impossible before virtualization was around to reduce the hardware requirements for enterprise lab environments. This course is also the first one I’ve been to that has some users in the local office and some using gotomeeting to attend the training over the internet. So far I think the arrangement has worked well for the internet users although I feel sorry for the person in Washington who has to start work at 6am due to the time zones. I was surprised that they were not using LiveMeeting to host the training (as this is a Microsoft event) but apparently the screenupdates were not been fast enough for the remote users.

I’ll be posting a few links on my twitter account – helsbyhome, and my absoblogginlutely delicious account  as the course progresses. Mostly these are links for extra tools, utilities or downloads to assist in the management and implementation of Exchange2010.

Sorry for the weather in Columbus, Ohio – we’ve migrated to Exchange 2010 No comments yet

My company would like to apologise for the weather (ie tons of snow) that Columbus, Ohio is currently experiencing. We believe it is entirely our fault as we have started our migration from Lotus Notes to Exchange 2010 – something I believe would only ever happen if Hell froze over. Therefore we are totally to blame for the weather.  Thankfully there is no way we are going back to Notes, so it looks like this weather is here to stay.

Security warning pops up when using Outlook2007 and Exchange 2007 No comments yet

After a recent migration of mail to Exchange2007, we’ve just started getting users logging tickets where a security window pops up saying “The name of the security certificate is invalid or does not match the name of the site”. This can happen even when the client is not at their desk. It took a few seconds to work out what was causing it – the clue was that the window had an icon in the taskbar for outlook. Searching in Google found Microsoft’s KB article 940726 with the resolution to the fix which involves changing various internal url attributes.
The instructions are fairly straightforward but I wanted to see what the values were set to before making the change. As I’m not very familiar with powershell it took me a while to work out what I needed.
For the command

Set-ClientAccessServer -Identity Servername -AutodiscoverServiceInternalUri https://name.contoso.com/autodiscover/autodiscover.xml

you want to run the command

Get-ClientAccessServer -Identity Servername | fl
The pipe fl provides all the values in a list – if you don’t include this part of the code you will end up with one line containing the name of the server – a value that you hopefully know already!
I really need to get cracking on my powershell skills – I still prefer good old fashioned dos batch programming but now that we’ve started to roll out powershell across all machines, powershell skills will be in demand more and more.
