in Exchange I came across an issue at a client where for reasons as yet unknown about 15 users across various servers/databases in a single DAG suddenly had their mailboxes disconnected and a new one created. Now the mailboxes had different GUIDs of course, but they had the same LegacyExchangeDN and the users were now […]
Exchange Copy-MailboxFolderPermission
Are you sometimes asked by VIPs to get Folder Permissions sorted out in Outlook when they get a replacement PA? Of course this can be done by the VIP themselves, but what if they have > 100 folders? Outlook permissions don’t inherit down, so it isn’t enough to just set the permission at the top […]
Exchange Replication over a Split Network
Let’s start off by explaining what I mean by Exchange replication over a split network. I am talking about a DAG split over two Data Centres (and AD Sites) with separate links for replication and for user/MAPI traffic. Although let’s also quickly add that Microsoft now recommends that you only do this when you have […]
Active Directory Authentication – Part 2
In part 1, we talked about authentication via NTLM and how the domain controllers that are used to authenticate you are the ones near the service that is being consumed. Now let us move onto Kerberos. Just like last time I need to point at a TechNet Article, How DNS Support for Active Directory Works. […]
Active Directory Authentication – Part 1
Today we are deviating away from the more Messaging related threads and we will be looking at authentication. The reason for writing this article is that I am often asked to troubleshoot authentication issues and to my surprise there are not many simple explanations about how authentication works. Also I find time and again that […]
Migrate from Lotus Notes
It’s a stampede… In my humble opinion I believe that IBM could have saved themselves from the juggernaut of Notes to Exchange Migrations. More accurately stated, it is in fact “Domino to Exchange” and “Notes to Outlook” migrations. Why is that relevant? The fact of the matter is that user’s actually don’t care about mail […]
Permissons and Delegations – Lotus Notes vs Outlook
Lotus Notes ACL & Delegation versus Outlook Permissions & Delegation – Part 1 By Conrad Murray Introduction Delegate Access is most commonly used between a manager and assistant, where the assistant (delegate) is responsible for processing the manager’s incoming meeting requests or email messages and coordinating the manager’s schedule. Delegate Access can be used […]
Optimizing Autodiscover
The Outlook/Exchange autodiscover process has been well documented by Microsoft (http://msdn.microsoft.com/en-us/library/office/jj900169(v=exchg.150).aspx) The basic steps are Find Service Connection Points (SCP) in AD check those records where keywords attribute contains site= matching the user’s AD Site check those records where keywords attribute contains no site= at all check those records where keywords attribute contains site= but none match […]
Domino Directory Cataloger (dircat) does not replicate updates
In a large organisation I found that a domino directory catalog consolidating about 5 large domino directories did not have all documents replicating and was completely out of sync…. There are a variety of reason why directory catalogues are used. For most organisations it is simply to have a consolidated directory from multiple domino directories to […]
TEN good reasons to keep a Hybrid Exchange Server
Numerous companies are now looking at the cloud for their mail system. Office 365 migrations are happening everywhere, but there are good reasons why you should consider keeping at least one Exchange Server on premise, i.e. Hybrid mode. The first three reasons come into play when migrating either cross forest (e.g. from a Resource forest) or when […]
Avoiding and converting winmail.dat Files
Avoiding winmail.dat files in Domino It’s happened to most Notes users at one time or another: someone who uses Outlook sends you an e-mail, and instead of getting a nicely formatted message with an attachment, you end up with some plain text and a big file at the end called either “Winmail.dat” or “ATT0001.dat” […]
Configuring TLS between Domino and Exchange
Introduction In the modern messaging world Transport Layer Security has become the norm and given the ease at which Microsoft Exchange is able to achieve this out of the box, organisations quite rightly demand this when they are on Coexistence mode between IBM Domino and Microsoft Exchange. Up to Domino 8.5.x Domino does not actually […]
