Outlook 2010 error message - pst file has reached maximum size

Posted on 2012-08-15

I'm running PC with Windows XP.  

I used to run Outlook XP (2002).  I upgraded to Outlook 2010.  

I now get the following error message when I launch Outlook:  "Cannot turn off the reminder.  You may be reminded again.  The outllok data file C:/Documents and Settings\[my name]\Local Settings\Application Data\Microsoft\Outlook\[my name] Folder.pst has reached the maximum size.  To reduce the amount of data in this file, permanently delete some items that you no longer need.  YOU COULD ALSO CONSIDER USING THE NEW OUTLOOK DATA FILE (.PST) INTRODUCED WITH OUTLOOK 2003 THAT PROVIDES GREATER CAPACITY FOR STORING ITEMS AND FOLDERS."

How do I use the "new Outlook data file" to get me out of this mess?

    pst files have a default size limitation.  once a pst is broke its typically not recoverable.  you can mount it and look at it but no longer use it.

    I've had problems before with the file size limit problem (but found workarounds with archiving, starting new pst file, etc...).  

    In this situation, I'm not sure what will get Outlook running again.  Any suggestions?

    Oh, I should have added that I'm willing to lose everything in all of the pst files I've got.  I don't need 'em.

    are you unable to open outlook at all? if you don't care about the PST files, use control panel -> mail to remove the profile, and recreate a new profile. set up your email address/server etc, and it will open outlook with only your mailbox and no PST files.

    you can always also use the scanpst repair tool to fix the pst file. if you can open the pst file, you can delete some messages, and even move some folders to a new PST file, so you split the file size.

    If you don't need the emails from that pst file you can delete the file and try to open Outlook again. It should recreate the file with no emails.

    Also, when you delete emails, the size may not reduce. You need to compact your pst file do see a difference. Here is how to do it: How to compact PST and OST files to eliminate deleted item space in Outlook.
    Be aware than it's a good practice to keep your pst file under 2Go.

    if youre willing to get rid of everything delete the mail profile from inside control panel and completely recreate the mail account.  that will be the easiest thing to do.

    I created a new PST file and moved some folders to the new PST folder to split the file size.  Worked great...didn't know you could do that.

    Lots of other good suggestions too...thanks to everyone who posted solutions!
