Last week in part 1 we looked at the background on PowerShell, explored terminology and some basic commands.

17th October, 2014

Background As we know Microsoft is firmly banking on PowerShell to be THE way to manage all of their operating systems and services, and with good reason.

Factors affecting Migration velocity

26th September, 2014

After a lot of experience in the field I’ve tried to bring together a bunch of items to consider when embarking on a Microsoft transformation. This blog is really directed at the Migration side of such a project, however many items are shared with coexistence.   The list may seem quite large, but in actual […]

Exchange Cascaded Folder Permission

19th September, 2014

If you have ever done delegation in Lotus Notes and were then migrated to Outlook you would have noticed one big difference…  cascaded permissions!!!  We have asked Microsoft why Outlook permissions behave so differently to NTLM permissions but we haven’t had an answer.  At the recent MEC a number of people were asking the same […]

Restoring a Disconnected Mailbox

5th September, 2014

 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

29th August, 2014

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 […]

Migrate from Lotus Notes

1st August, 2014

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 […]

Domino Directory Cataloger (dircat) does not replicate updates

11th July, 2014

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 […]
