Read about Outlook personal folders in the hits of http://www.google.com/search?q=outlook+-express+-backup+%22personal+folders%22
There's a personal folder backup tool also, but I've excluded hits about that to keep the picture clear. It really depends on the way her data is backed up if that is relevant at all.
Note the 2Gb max file size of Outlook pst-files as discussed in http://support.microsoft.com/kb/832925. If they grow above that, they might very well become corrupted and unusable. That's one of the best arguments for splitting!
Hope this helps.
Hi, I have a friend of mine wich normally has a large e-mail traffic at his workplace. She would normally trafic some 3MB of e-mail daily (because of the attachments). This way the database of outlook has grown that much that it takes half an hour to compact the folders, and a lot of time to start also.
The solution I thought, was that of dividing the database in to pieces, the older messages should be passed on to another identity, freeing up this way the current identity. If she has to refer to any old message she can then change to the old identity.
Do you have any suggestion? Deleting is not an option
Thank you Toni
