Maximum number of mail folders ? Outlook 03

[soozle]

Has anyone come across a maximum number for folders in a users mailbox. A user has approx 160 folders just under the mailbox folder on the same level as his inbox and he's having one or two odd problems. I'm thinking it may be to do with the sheer number of folders and not the actual size of them (1.3GB in total)
TIA

I ran into something similar. A user created the alphabet folder list, 24 floder and subfolder within them. We had to have her truncate letters A-C, D-G etc…. Her issues went away, never learned about any limit though. There are performance issues in .pst and the .ost if it grows past 1 gig

thanks - nice to know I'm not alone. I'll have to try and talk him into a restructure.

I found this on microsoft.com
"The .ost file can contain as many root folders as you desire and each folder can contain a maximum of 16 kilobyte (KB) subfolders. The .ost has a 16 KB folder structure by default, and this cannot be upgraded to allow large tables. The total file size of an .ost cannot exceed 2 gigabyte (GB). " But I'm not sure what it means by "a 16KB folder structure" or "a maximum of 16KB subfolders"
can anyone put this in English?
TIA
