hi diane, firstly thanks for your work with scripts and mfcmapi etc, it has helped me out previously with imap to exchange migrations.

however, this time, i have a weird issue. i have 9 mailboxes with thousands of folders from gmail. ive connected via imap, and exported to a pst.for each account.

i was then going to use your script to change the PR_CONTAINER_CLASS attribute prior to importing to exchange, but i thought id check one pst file first with mfcmapi manually.

the property PR_CONTAINER_CLASS does not exist at all in any of the folders. im in the middle of the migration and the customer is getting a bit twitchy - any chance you can tell me what i should do?

the mailbox in question im looking at with mfc mapi was connected to gmail via outlook 2007. is it because of 2007 that this has occurred? thanks in advance for your help.

the two files attached are the mfcmapi display for a folder in that mailbox. slipstick1 is the left hand side, slipstick2 is the right hand side of the window. (screen wasnt wide enough to do screenshot of whole width at once)

well, just an update to this - it looks like it doesnt matter, outlook seems to assume by default that it is a mail folder. id still love to know why the property doesnt exist though!
