Replacing a corrupt mailbox in exchange  - best way to achieve

Hi,

Cutting a long story short we have a user who's iphone is not getting incoming emial via Active synch. We have done thorough invesitgaitons and concluded there is a problem with his mailbox (other users work fine).

The problem did start occuring when he moved many emails out of his main inbox into PST files. AT this point he stoped receiving emails on his iphone.

As others users work fine with iphone we have to conclude it's his mailxbox.

It has been suggested that either we perform an exchange mailbox defrag OR we export all the emails. Delete the mailbox through "exchange tasks" and then create a new one and re-import.

1) I welcome if there are other opinions on which is the best approach
2) does anyone else know of other ways for reparining the mailbox.


Thanks in advnace for any input.

Obvious question, but you have deleted and re-added the user account to the iPhone, right?
try to delete iphone profile and re-create it.
Exmerge seems to be a good option .

Trust me, I have spent two days trying different iphones and this particular account exhibits the same on any iphone or any windows mobile device for that matter. I've had an exxpert assist in this area. Lets please focus on how to fix a mailbox.

Were it me, i would use exmerge to dump the data out of the mailbox and recreate it. Approximately how much data are we talking about (what is the size of the mailbox?) and what version of exchange do you have?

My first suggestion would be as CorruptedLogic stated, do a reset on the phone.  If that is unsuccessful, try on another activesync device.  if all of these are unsuccessful, or you just want to go ahead and recreate the mailbox, make sure you do a few things first.  Export all email using Exmerge for Ex2003 or export-mailbox for Ex2007.  In AD, get any email address aliases that he has added to his account.  Grab the exchangeLegacyDN from ADSIEDIT.  All of this will be important later.

Go ahead and remove the mailbox.  When you create the new mailbox, make sure you create on a seperate store.  Once the mailbox has been stamped by the RUS(Ex2003 only), go ahead and add the smtp proxy addresses back.  You are also going to add a custom proxy address.  The type will be X500 and the value will be the exchangeLegacyDN.  This will allow names caches to work as well as "Replys" to emails from his old mailboxes to reach him.

Import the mail back into his mailbox.

Test.

For those that are interested the actual error in the event log many Multiple times (e.g. we had about 500 entires of this in the space of about 3 minutes) is the following:

Unexpected Exchange mailbox Server error: Server: [SERVER.DOMAIN.local] User: [TEST@COMPDOMAIN.com] HTTP status code: [409]. Verify that the Exchange mailbox Server is working correctly.


Now the solution for this does point to active sync related errors, but all other accounts on active syn work fine and we have really checked it out. The problem only happens on this one mailbox regardless of the device we use.

PLease help!
use Exmerge before doing that you can remove Exchange attributes of the user and re-connect the mailbox and then try to sync after creating new profile if that doesnt work use Exmerge.

Now were talking. This sounds like a good area. The mailbox is about 500MB and it's exchange part of SBS 2003.

I was going to go to bed now but this Exmerge sounds good so I might try now.
Would be a real bonus if I could sort by the morning.

"Unexpected Exchange mailbox Server error: Server: [SERVER.DOMAIN.local] User: [TEST@COMPDOMAIN.com] HTTP status code: [409]. Verify that the Exchange mailbox Server is working correctly. "

That error is usually caused when the default domain email address (user@domain.local) has been removed from the user account properties. It doesn't have to the be the default address.
It is an account specific problem though.

As for your specific question, what I would do is create a new account for the user. Ensure that the new account connects to the ActiveSync correctly etc.
Move the email address, permissions and memberships to the new account.
Move the data to the new account.
Forward the old account to the new account. Hide the old account from the GAL.

That way, any meeting requests, nickname file entires etc continue to work.
The account is NOT deleted.

cmccall, your post sounds great. AS someone who has not done this before, how long do you think ti woudl take me to complete. Bear in mind is's already 1am, I'm tired, but the boss is going to be P***ED (and I've already spen the last two days in fear of my saftey)

I've never done Exmerge (but will google now)

Mestha, again intetesting advice, however will not creating a new account for the user mess up his actual windows login setup? I was hoping to just create a new mailbox (hence exmerge sounded good).

Or is that what you mean anyway

One last thing for cmccal, when you say create it on a different store, I did not think you could have different stores on SBS. Will this be a problem?

Given the error, I don't think it is the mailbox at fault. It looks to me to be account related.

Hmmm, wha tdo you mean by an account related error? I know it seems obvious, but how does one fix an account related error and what sort of thing would cause it?
Assuming I have to follow your easlier suggestion of creating a new account. is that an account with a different username?
The steps you describe, will that maintain all aspects of the users account?

Would we still not have to import the emails into the new account and create a new mail box for the new account.
Do you mind eplaining a bit more to, who you can tell is an obvious -non expert.

Thanks for all help so far!!!

Can I also add, that when we synch the problem account, calendar synchs, ocontact sycn, and have even managed to send email. Just not showing emails from the inbox?

And remember the user reported the issue occuring when he moved emails from his inbox into PST archive folders. So was doing some big email data movement.

does that change anyone's opinion on what the main problem is?

cmccall:,

That links looks promising!!!!!

He's not nice to talk to as he is extermelly impatient, so if anyone has an iphone who can post the steps to take the email out of the synch schedule I would be most greatful.

I know all you gus have gone beyond duty on this ticket already!

Actually Ithink I have found a good picture which will be good enoguh. Thanks, I'll let you know how it goes.
does outlook web access work for this person - does it show mail in his inbox?
you talk about he moved mail to a pst file - is his outlook saving his emails to a personal folder or to mailbox:username.

Author

Commented:
Outlook and OWA work fine. There are no other indications of any  problems with his email account other then the iphone / mobile device not showing emails in the inbox.

When I say move to a PST file, this was for archving. Se he moved from the Exchange mailbox on the server to a local pst file.

OWA all fine.

Can ven send emails from the mobile device, inbox always remains empty.

Author

Commented:
that is, empty on iphone
time and date issue?

Commented:
In what way, you mean the time set wrong on the iphone or something?

I have a moemnt of reaslisation. I remember seeing one of the Archive folders called "Inbox" I remember thinking this was a bit strange but I now suspect the userdragged the entire Inbox out of his exchange folder into an archive PST folder.
Then I guess automatically this has created a new inbox because there had to be one.
And this is screwed up the sycn with the inbox.
Just a theory, but thinking about it it makes sense.

After many hours solved (we hope but so far so good) by creating a new account and moving everything over to this. Did try reconstructing the mailbox first but this did not help. Same problem.
Hopefully there will be no follow up problems.
Thanks for input.

Creation of the new user account is what fixed this.
