Outlook 2002 cannot send or receive e-mails

I am using Outlook 2002 (10.6515.6735) SP3 on Windows XP operating system. My .PST file has reached a file size of 1,910,992 Kb. I was trying to send an e-mail with a 2GB .jpeg file attahachment and started getting the error "the messaging interface has returned an unknown error. If the problem persists restart outlook" It appears that my .pst file is approaching the 2GB limit but it is not there yet. I have very important emails in the .pst file. Is there a way to resolve this issue?
I read on this forum that Outlook 2003 has a limit of 20GB. Is that true ? If so and I upgrade to Outlook 2003 will my problem be resolved??
 Please help my job is on the line..

Greetings, shubim !

Outlook 2002 has a PST file limit of 2GB.  So you have 1.9 GB now, and you want to send a 2 GB attachment. Outlook 2002 will not let you send such a file this large.

2GB attachment is a hugh file.  JPEG file normally is not that large. Do you mean 2GB or 2MB attachment?

Yes, Outook 2003 will allow your PST file to grow to ~20GB, but you will have to use the Outlook 2003 PST fle format, unicode.  This means that you need to copy the old PST to Outlook 2003 data folder.  Open up the old PST file in Outlook 2003, create an new Outlook 2003 PST file, and drag the emails from old PST to new PST.

Best wishes!
