The SMTP address of the deleted user has been added to the user, and sending mail is unreachable as an alternate SMTP address

Problem Description:

So, there are 2 old users, [email protected] and [email protected].

Now delete Wangdong This user, add an SMTP address to Wang's user: [email protected], then I use the Outlook client to create a new message, enter [email protected], Outlook client automatically resolves me to a Chinese name "Wang Dong", I can not modify, click to send the message, return the letter error: imceaex-_o=first+20organization_ou=exchange+20administrative+ 20group+20+28fydibohf23s[email protected]abc.com

Remote Server returned ' 550 5.1.1 RESOLVER. Adr. Exrecipnotfound; Not found '

The problem is that the Outlook client automatically matches the wangdong to [email protected], which is recognized as

[email protected] This deleted old user.

And when OWA sends to [email protected], it can be served normally.

Problem Analysis:

owa can work correctly, think gal The new e-mail address has been successfully updated.

Then there may be 2 possible reasons:

1. The OAB is not updated or Outlook is local The problem with the cache.

2, Exchange function settings (deleted [email protected] This user's mailbox has been saved in exchange for a period of time, easy to recover mailboxes, deleted recovery, etc.)

Processing method:

1. Manually update the OAB

Refer to Microsoft Knowledge Base https://support.microsoft.com/en-us/kb/2784785

2. Completely delete deleted user mailboxes saved by Exchange

Get-mailboxdatabase | Get-mailboxstatistics | Where {$_. Disconnectreason-ne $null} | FL Displayname,mailboxguid,database,disconnectreason

The above command gets the user mailbox information that is still retained after the local Exchange server is deleted

The database and Mailboxguid are then obtained according to the previous command to execute the following command to remove

Remove-storemailbox-database mbd01-identity "2ab32ce3-fae1-4402-9489-c67e3ae173d3"-MailboxState Disabled

The above command will completely remove the data file of the mailbox, please operate with caution, the operation is irreversible
