    [@DH] Five times?? What, did someone lose their pictures once and that was the procedure put into place to prevent it from happening again? That’s like a first grade punishment, “Write on the blackboard five times, ‘I will not lose my pictures.'”

    And having to move a 15gb mailbox that way was worse than punishment; that was torture. You might have done better with a 56k modem.

    I have seen a few mailboxes nearly 50GB they were actually at a mining company security department. They are required to back up the images they take a minimum of 5 times (Desktop, Laptop, External HDD, Email, Offsite Email).

    But I guess it is not as bad transferring 15gb Exchange Mailbox over a 10Mbit Satellite link (shared by no less than 100 at a time) due to all external media being banned eg CD/DVD, USB devices all banned. It took me over a week to move it due the link being turned off every night local time and only being able to transfer in their daytime (4 hour difference)

    [@Coyote] Yes, that still applies. It’s not a problem, it is an optimization that helps keep the file from becoming extremely fragmented. Also, compacting a database in real time would severely affect performance.

    You can manually compact any PST or OST at any time within Outlook by right-clicking on the topmost item in the folder tree (above Inbox, usually ‘Personal Folders’ or ‘Outlook’), and clicking ‘Data File Properties…’/’Advanced…’/’Compact Now’.

    Or they never compacted the OST.

    That’s an MS Exchange offline store of an Exchange account. If it does represent the size of the mailbox, I’d like to meet the Exchange admin that permits that (let alone the boss who funds the storage for that).

    I bet the mailbox would be bigger if the user know it could be made so. The default maximum size for a PST or OST in Outlook 2010 and 2013 is 50 GB without changing the registry.

    Performance is probably terrible. From http://support.microsoft.com/kb/2695805/en-us :

    When you use Outlook 2010, the following .ost size guidelines generally apply:

    • Up to 5 gigabytes (GB): This file size should provide a good user experience on most hardware.

    • Between 5 and 10 GB: This file size is typically hardware dependent. Therefore, if you have a fast hard disk and lots of RAM, your experience will be better. However, slower hard disk drives, such as drives that are typically found on portable computers or early-generation solid-state drives (SSDs), experience some application pauses when the drives respond.

    • More than 10 GB: When the .ost file reaches this size, short pauses begin to occur on most hardware.

    • Very large (25 GB or larger): An .ost file of this size increases the frequency of short pauses, especially while you are downloading new email messages.

    And 1/2 those attachments are probably attached to forwarded, re:, cc:, and Bcc:’s of the original email.

    I just wonder if outlook still have the problem of if you delete an email it doesn’t actually remove it from the pst/ost file so you wind up with gigs of unrecoverable space.
