Outlook pst too large

Hi,
just today, one of our users reported that they  could not send out emails and that the messages were stuck in her outbox.  My thought was to create another profile which would create a new pst since her existing one is nearly 50g due to lots of large 3D files accumalated over past few years.  Wanted to know if this is correct way to go about it.  Once i have the new pst created, i would then add that large pst as an additional data file so she can still view her old emails and attachments.  Since the new pst will start out with the much smaller default size, she can hopefully send out email again.  Sound correct? Any other ideas?  Thanks

That's one way....

Another is to tell the user to delete some items and compact.

Another is to increase the limit:
You need to go to the following location in the Registry;

    Outlook 2003
    HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\PST
    Outlook 2007
    HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Outlook\PST
    Outlook 2010
    HKEY_CURRENT_USER\Software\Microsoft\Office\14.0\Outlook\PST
    Outlook 2013
    HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Outlook\PST

Here you must create and set 2 new DWORD values (note that these values are case sensitive);

    WarnLargeFileSize
    Don’t set this higher than 4090445042 (decimal) or f3cf3cf2 (hexadecimal)
    MaxLargeFileSize
    Don’t set this higher than 4294967295 (decimal) or ffffffff (hexadecimal)

It's good to have that option of increasing the pst limit since her pst is local and she has a 1tb drive but at the same time I don't want her to keep saving those large attachments and growing the pst too much more. She doesn't wanna go the other route of deleting old emails since she thinks she will need them down the road.

If I use archiving will she still be able to easily view those archived emails?

Yes. Archiving creates pst files.. It is similar to what you intended to do, but is built into outlook.

AutoArchiving can work... but your plan is basically doing the same thing.
