    Let’s leave the “ why would you? ” to one side for the moment but is it actually possible or supported to defrag a continuous replication target database?  Well not surprisingly er ‘No’.  An offline defrag creates a new database with a new signature (“When defragmentation is complete, the original...
  • Blog Post: Why so much fluff?

    When you use the Exchange 2007 Mailbox Storage Calculator on the face of it you seem to get a lot of fluff added to your storage design.  ..fluff upon fluff.

  • Blog Post: 3 Data Centres and a File Share Witness

    What’s the guidance if you’ve got 3 data centres, you're stretching Exchange 2007 mailbox CCR nodes between two of them and the link speed and latencies are similar between all 3.  Should you put the File Share Witness (FSW) in the 3rd data centre? In my opinion yes I would recommend putting the...

  • Blog Post: 24 hour operation, several thousand mailboxes, high concurrency, heavy profiles – how do you tune Online Maintenance?

    For companies who have to support a lot of ‘heavy usage’ clients connecting to their Exchange 2007 platform 24 hours a day, tuning online maintenance is going to be important.. You have to be quite careful about staggering online maintenance to minimise its impact on performance and it can be a bit of...

  • Blog Post: Archive v Big Mailboxes
