PSTs and invisible messages in IMAP folders

Hi Folks,

Client had their email set up with Google Apps and was accessing with IMAP. At some point later they started pulling it all down with POP3.

Last weekend we installed an SBS2011 server with Exchange 2010 and used the import command to bring the mail in. What I find now is that each inbox has a number of subordinate folders of type IMAP.

*** If the user drags a new email from the Inbox into one of these type IMAP folders, the email vanishes. *** I created a new folder which is not type IMAP and dragging into those is no problem.

I exported one of these type IMAP folders to a separate PST and I can see that the folder is still type IMAP. Also, the vanished messages have not reappeared.

So... is there a way to re-type these folders from IMAP to normal? The alternative will be to manually recreate the folder structure for every mailbox which is NOT a task I care to do. Can the messages from today that have vanished in the dragging, be recovered?

Thanks

That is to be expected.. it is only an import folder you cannot really write to it.

This is correct.. with gmail all of the messages are in the 'all mail' folder, I excluded all of the other folders when I set up the import.csv

Thanks for the confirmation. Still need to see if we can find a way to recover those emails.
Eventually rebuilt the mailbox by creating a PST and manually recreating folders and dragging the emails. Unable to recover the missing emails :-(
