Good evening, 

I have a Macbook Air from 2011 and have moved from Outlook to Mail as I had to continue duplicating the mail identity and Outlook was not working properly. However my 'Message Sources' folder continues growing to a point that I hardly have 1 GB of space left. Would anybody be able to advise if I can delete the 'Message Sources' folder without affecting my emails (or Word, Excel or any Microsoft programme that I continue using) given that I will not be using Outlook any longer in this computer and I will be using Mail?


Many thanks

Ignacio

My Outlook 2011 running under MacOS X 10.7 is constantly filling up the folders under Data Records -> Message Sources with what looks like the same message source files over and over again, at least once a minute. It keeps on as long as the Outlook application is running, day and night, and regardless of any real incoming e-mails.

One of the files is 7.5 MB and this one quickly fills up all available hard disk space. My Message Sources folder now contains a whopping 167GB...

Any ideas on how to stop this? Please help!

Best Regards,
Markus
So, I replace an user's mac and i moved his Folders, message sources, and messages, from the old main identity to the new one on his new mac; but i forgot the move the "message attachments" folder. Now he sees all his emails, but none of them have attachments.
So, it has been 2 days and he noticed this and has been archiving new emails with attachments.
My question is: When i move the folder "message attachments"(from his old mac that i have) into his main identity and replace the current one and rebuild it, it will get rid of the attachments for those 2 days.
How can i merge those two folders together so when i rebuilt it, it has the old attachments and the new emails with its attachments as well.
is this doable?

I've seen some related posts but none seem to directly address why this happening or how to fix. In my Outlook for Mac 2011, my 'message sources' folder is a whopping 65 gig. It's killing my MAC Air. My email inbox only has 30 messages in it. I have dragged emails to an offline folder but, even then, the file wouldn't be more than a gigabyte.

So, can anyone please advise how to reduce this folder size?

Many thanks

Every day I get a warning message that yet another 1% of my hard drive is gone. Since I am not saving any big files like pictures or music on it, primarily only Office files, I couldn't figure out where the space was getting eaten up from.  I used WhatSize to investigate, and the hog turns out to be Outlook. 33.5 GB is for message sources.  What is "message sources"?  How can I keep this from multiplying so fast?  I only have 5% left on my hard drive.  The 2nd biggest thing on my hard drive is Application Support at 15.2 GB, so it seems that Outlook is clearly the hog.  How can I control this ravenous beast?

P.S. There's also 2.31 GB for Outlook 2004 identities.  When I got this computer, I transferred the user to here, and my old computer had Outlook 2004.  Can I get rid of that?
