Hi - do you know what the effect of using set-imapsettings -enableexactRFC822Size:$True is? I have some IMAP customers who use PINE and/or ALPINE, and Exchange supplies different message sizes to those clients during message retrieval. ALPINE warns the customer of this message size discrepancy when attempting to move items to folders. I am aware that Exchange is not a IMAP server. When i dumped my IMAP config (looking to see if there were settings like fast message retreival, etc), I saw this option set to False, and the name sounds like it may be a setting to correct this issue. Do you have any info on this command? The detailed and full help data do not list the details of the parameter, and I haven't seen it in the documentation on Tech-net.

Any info you maybe able to provide might be helpful. TIA

Exist a lot of good programs on my PC. But the day before yesterday I stumbled upon a bad problem with damaged Exchange info. For luck kept my head and chose one tool for solving, which was successful. It might be good determination for solving this trouble - microsoft exchange email recovery.
