Exch2k10 - after migration from Exch2k7 - only one mailbox cannot receive (ext/int) emails but can send

Question

Hi,
after migration (coexistence) from Exch2k7, we have only one user (among 160) who cannot receive emails, doesn´t matter if it´s comming from internal user or external and also doesn´t matter if we are checking that mailbox using MS Outlook or OWA interface;
right now I performed a test to redirect (message mailflow) its mailbox to another and it works; I tried to redirect and also save a copy to himself but no success. After disable that redirection, the issue remains the same.
If we use another mailbox with Ms Outlook to send new mail and set the notification for delivery/read; we receive an alert regarding the 'delivery' only.
Using MessageTracking CMDLET to .CSV file, shows the following - when send externally to this user/mailbox:
SMTP ; RECEIVE
STOREDRIVER ; DELIVER
If we use the CMDLET 'Get-Mailbox -Identity "Exchange2010User" | FL' for this user and to another working fine, there is no differences.
That mailbox resides on a database with more 15 others users and using the CMDLET 'get-queue |where-object {$_.NextHopDomain -like "mbx2"}' show no messages waint for delivery.
>>> Can someone help us to troubleshoot this case? Any help is appreciated.

Answer 1

did you check if you have anything like a retention policy or managed folder mailbox policy set for the problem mailbox ?
Journal Rules ?
Outlook Client/Server Side rules ?
did you check if you are able to locate emails in Recover Deleted Items after you logon to user mailbox ?
