Hi

In practise, what is the maximum attachment size for an email when
using Outlook 2003, before Outlooke become unstable?

Background
To keep the .OST files small, we are now archiving emails to that are
more than 1 year old, to .PST archive files and our .OST files are now
down to less than 1GB. We also sometimes run SCANOST.EXE for good
measure. Nonetheless we keep finding that Outlook2003 (running under
WindowsXP) become unstable when files of say 7MB are attached to
emails.

Any thoughts?

With thanks

Attachment size does not have a destabilizing affect on Outlook; that I know
of. OTOH, most E-Mail Service Providers place limits on the size of the
e-mail passing through their servers. Largest I know of is 25 MB; total
email size (attachment + body). Moreover, if your service allows 25 MB, but
your correspondent's service only allows 10 MB (most common size allowed),
you can't send an e-mail larger than 10 MB total size, or your
correspondent's servers will reject it.
 
Running scanost (and scanpst) "just because" can cause more problems
than it solves. Also, While smaller data files (ost or pst) makes
outlook faster, if you leave the archive pst files attached, it can slow
outlook down and make it unstable if have "too many".

I don't think the attachment size is what is making Outlook unstable -
the problem just shows up when you are attaching larger files. Are the
files you are attaching local or on a network share? Outlook can be
sluggish when you attach files from a network share and larger files
require more time to pull across the wire.
