Can you synchronize those mailboxes ok?

Yes i made the sync for that users but after i'm trying to start the task i have no mailboxes found. for one exchange server i had resolved by renable the user but i think it is not a good solution

So when you re-enabled that user did they show in the New Mailbox list or the Disabled Users Mailbox list?

they appear in new mailboxes only and also with archive completed and with status new

Is your SQL Server also on your EV Server?

Do those mailboxes still have shortcuts to archived items?  If yes, can you recall archived items in Outlook?

It sounds like you zapped all your mailboxes with EVPM, did you run any EVPM scripts?

No, my sql server is running on different physical machine.

Yes and i can recall archived items only oppening them from outlook beacuse i don't have the ev shortcuts in my outlook. after i had re-enabled the users the buttons appear in outlook.

What is EVPM ? i didn't run any script.

Weird scenario and it will be hard to pen down exactly what happened.  I think you best option is to just re-enable your users and move on. 

I would also be sure that your backups are running correctly.

Are you doing this as a production install?  If so, it might be worth have a consultant assist you.

weired scenarios yes, now i was looking why i don't have new items archived and i saw that i don't have mailboxes available . the users appear again in status new and i need to reenabled them but i don't know why

is this a production or lab environment?

What verions of Exchange are you targetting and is that Exchange Server production or lab?

is a lab to production environment :) exchange 2003 production

So do the archives and indexes dissappear? 

Do the shortcuts to previously archived items still show in the Exchange mailbox?

It sounds as though your system is being reset, either on the EV side or the Exchange mailboxes.

i have all data in place. i also can read old archived items. no downtime on EV or Exchange.

i don't understand why mailbox state becomes new for allready enabled users but they still apear under Archives -> Exchange Mailbox

i think something is happening with DirectoryAccess database and that changes the value for ArchivingState..

Agreed with tony on this, typically the only thing that would put a mailbox to a New state after its enabled would be a zap through EVPM.

But remember that the archives and mailboxes are really seperate entities, you can have archvives regardless of whether the mailbox becomes disabled or deleted,

In a test environment i wouldnt be surprised if people delete and recreate mailboxes within exchange as a test and whats being shown as a new mailbox is in fact, a new mailbox, it just happens to be that it hasnt been assigned an archive or enabled yet.

I would be interested in knowing if you have duplicates in the Exchange Mailbox Entry table and whether they have different MbxGUIDs and/or LegacyExchangeDN's

i'm not ussing evpm it is only a fresh install in a envoirment of 6k users with only 4 users enabled. at this time happens for all 4 users and for all exchange servers (task)

it is not a test environment and i'm my using my own email for testing.

i had reenabeld the usrs and export the exchangemailboxentry  where MbxArchivingState=1 to see if something is changing.

I thought you said it was a lab to production environment?
And also are you saying you re-enable the users and they keep getting set back to New and you have to enable them again?

is installed in a production environment

yes i just re-enabled the users in this morning and i'm waitting to see when they are back to new again now

After you enable the mailboxes do you happen to see a message without a sender and with an attachment named Evsetting.txt?

I am not referring to the Welcome Message.

no i get only the Wlcome Message in my inbox

i figgure out that this happens every day at 00:00 AM

So the question is what processes run against Exchange before midnight?  Something is removing the hidden message from Exchange in between the noon and midnight run of automatic synchronization of the Archive task.

Also, what do you use for anti-virus?  I seem to remember a case from a long time ago where AV was actually quarantining the hidden message.

i can't figgure out... i've exported all archived items back in my mailbox.. after that i had delete the ev server and create a new one with settings on default. and i had enabled my account. now at 00:00 my account get status new.

no antivirus installed on the machine :)

It would be the AV for Exchange if it is AV at all.  It isn't going to be on the EV side, something is happening in Exchange that removes the hidden message and it happens before 00:00, that is just when EV synch's the mailbox and no longer finds the hidden message.

i have only sep protection on exchange.. i also have enterprise vault v5 in the same domain for the same exchange exchange server could be a problem ?

YES!  you can't target the same Exchange server with two different EV servers. 

i thought so :) but i don't know in ev 5 how to disable an exchange server i don't have anything like target there only archiving service and retrieval service

i have ev 5 in production :) but for few users ( arround 20 ) but from top management!  I just stopped the services to see if tomorow morning at 00:00 i will have the same situation. is it enough to put all de services in stopped status ?

Yes, stopping the service should keep it from updating the mailboxes. 

one question,

after i had restore my items back to inbox and create a new ev server my items don't get archived back

in dtrace i have :

You need to set the IgnoreEVDates registry key.

Create  the REG_DWORD IgnoreEVDates in HKEY_LOCAL_MACHINE\SOFTWARE\KVS\Enterprise Vault\Agent.  (remember if 64 bit it goes under WOW6432Node)
Set the value of IgnoreEVDates to 3 (decimal), then restart the archiving task.

Tony , you rule! it's 12:46 AM and my users are still available for achiving :) thanks ! but i had disabled all services on EV5.0 what service should i start ?  how can i move data from ev5 to ev10 ?

to be honest, for 20 users, just start the Admin, Directory and Storage service *only* and then just export them out to a PST file
