Moved an existing 2003 mailbox to 2007 and all new emails goes to Deleted Items. Works correctly as 2003 but not as 2007. It started out as a 2007 Room mailbox that migrated back to 2003 then back to 2007 as a User mailbox. Is there a setting I need to change?

Hi, This is because the mailbox moved from Exchange 2003 to Exchange 2007 became marked with Autoaccept instead of Autoupdate. Now please run set-mailbox -identity "user mailbox" -Automateprocessing autoupdate in EMS After that, please check this issue. Thanks Allen

Hi Allen, Iam having this same issue.I tried running your command in EMS and it tells me that "-Automateprocessing" is not a valid parameter. Thanks! Myke

Hi, Please try set-mailboxcalendarsettings -identity "user mailbox" -automateprocessing:autoupdate Thanks Allen

Allen, IhadUnregistered resource mailbox from Ex 03Then moved toex 07. Then I converted the mailbox to type room by running set-mailboxcalendarsettings -identity "user mailbox" -type room. After that I made it to Auto Accept set-mailboxcalendarsettings -identity "user mailbox" -automateprocessing:autoaccept What I have noticed is any update that I do on existing meetings it dosen't get Auto Accept reply. If i create new meeting request then I get acceptance. Also I get acceptance if I change this new meeting. But old meeting doesn't get reply nor it updates the calendar of he resource. What am I missing? Thanks Hemal Doshi

I've recently had 2 instances where a user's mailbox has had it's automateprocessing value set to autoaccept somehow. The issue surfaced because the users reported no new emails. Upon further inspection, I found that the messages were getting immediately deleted. These people have been with us for several years and are heavy email/blackberry users - so I know it is a recent thing. (One started this past Thursday, one this morning).I have a ticket open with microsoft, but no info yet. These mailboxes were migrated from E2003, but were never set as room/resource mailboxes. Any ideas what might be flipping them over? From the Exchange shell, it doesn't allow you to set this property unless you've already converted the mailbox to a room type. We're using a Blackberry server, BackupExec 12, and Symantec Enterprise Vault, so there are quite a few hooks into Exchange.The only recent change was a tighter restriction on message size on the previous Tuesday...thoughts?Rafael

I'm having the exact same issue. Starting just a few days ago, we have seen 4 user mailboxes do this, 1 of which did it twice the same day. The EMS command is easy enough to run to fix it, but I need to know why this is happening and how to prevent it from happening again. We also use a BES (although only 1 of the affected users is a BlackBerry user) and Backup Exec 12.5. These users have been on this Exchange 2007 server for almost a full year.We use WSUS, and sometimes forget to approve updates, but this seem to happen shortly after mass-approving updates. I know it could be a coincedence, but do you know if this happened after applying any Outlook specific patches?-DerekSr System Engineer
