Exmerge PST size limit and date settings

Posted on 2012-09-03
Last Modified: 2012-09-04
I have some automated journalling mailboxes on a SBS2003 filling up. The final archiving works well (creates a new PST every 2 weeks on a dedicated drive) though I need a copy of all messages archived available for various reasons.

I'm planning to use Exmerge to archive the contents to a .PST, since they can hold 20GB. We produce less than 10GB email a year.

I cant find a way to extract one month old messages, only hard set date-limits and the documentation says the PST exmerge creates is ANSI-based and max 2GB.

For the dates I guess I can batch the .ini for every run .. sigh.. :-)

The PST size limit kills it all though...

Are there any other options?

I'd like to keep one month old messages in the mailbox and archive older messages to the PST.

    Exchange 2003 Mailbox to PST

    Key Features
    Export mailboxes from Exchange 2003 to PST files
    No size limits, can create PST for mailboxes over 2GB in size
    Standard PST format for files generated
    Easy to install with an intuvitive graphic user interface

    Or the other option could be to user Outlook to Export data above 2GB with Outlook 2007 and 2010.

    thanks for playing guys,

    I've turned on journalling and all mail are sent to mbox1. This box is available for inspection. I autoforward all mail from mbox1 to mbox2, keeping a copy in mbox1. Every 2 weeks mbox2 is archived on a dedicated drive. Mbox2 is never a problem.

    This leaves mbox1 filling up since it's max 2GB. Every week I'd like to archive mail older than 1 month into a PST, and that one max 20GB PST beeing open in Outlook.

    Of course Outlook has an (IMO not trustworthy)  autoarchiving feature, this requires some user to start Outlook, not good.

    The "Exchange 2003 Mailbox to PST" looks like a GUI around Exmerge (exact same input) and has the same hardcoded dates, not relative dates like "1 month old".

    Agree on the 20GB and Outlook issues with onpening such a Big PST :)

    Hope you were on Exchange 2007 or 2010 ... it would have been easy with scripting and scheduling :)

    Interesting points made by the other members and you will also want to consider the following;
    1.      ExMerge only supports the ANSI PST Format which has a 2GB limit
    o      ExMerge will not warn you if a PST goes over 2GB, it will just corrupt the PST and you won’t know it until you try to open it
    o      ANSI PST's actually start to degrade at about 1.8GB so I would not go over that limit in order to ensure the data is recoverable
    2.      Here is an article on how to script the creation of overflow PST's if you reach the 2GB limit and the updated script my Michael here

    Will just make copies of archived .PSTs for manual perusal, if needed. Thanks for input guys.
