Hi there we have a few accounts and all of them have x400 addresses. now we'd like to remove them from the users. what i've already done: i removed the x400 entry on the "default e-mail address policy" but on all user accounts the x400 still resists. question: how can i remove the x400 address for all the user accounts? maybe there is something to do with EMS? thanks for your input, uerueluem

In EMS, you can use a powershell script like this: foreach ($mbx in (get-mailbox -resutlsize unlimited){ $addrs = $mbx.emailaddresses |? {$_.prefixstring -ne "x400"} set-mailbox $mbx -emailaddresses $addrs -whatif } Run that, and if the results look right, remove the -whatif switch from the set-mailbox and re-run it to do the updates.[string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

I have changed the script a littlebit because it wasn't working as is. Now it looks like that: foreach ($mbx in get-mailbox){ $addrs = $mbx.emailaddresses |? {$_.prefixstring -ne "x400"} set-mailbox $mbx -emailaddresses $addrs } but even if I changed the script, it wont remove the x400 records from my Users :-( thanks to mjolinor

i also found another way to do it, but as the script also the program ADModify does not remove the x400 addresses. :( http://msexchangetips.blogspot.com/ --> Exchange: Bulk Remove X.400 Address Using Admodify

Mjolinor missed a “)” in the first line foreach ($mbx in (get-mailbox -resutlsize unlimited)){James Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

I also misspelled -resultsize :( [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

How's the result after using the modified script from mjolinor? I have tested it in the labJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com

The following Script worked successfully foreach ($mbx in (get-mailbox )){ $addrs = $mbx.emailaddresses |? {$_.prefixstring -ne "x400"} set-mailbox $mbx -emailaddresses $addrs -whatif } #to execute the script, remove the "-whatif", otherwise it's just a test

The following Script worked successfully foreach ($mbx in (get-mailbox )){ $addrs = $mbx.emailaddresses |? {$_.prefixstring -ne "x400"} set-mailbox $mbx -emailaddresses $addrs -whatif } #to execute the script, remove the "-whatif", otherwise it's just a test works for x500 thx very much

Can this be done using this method for Distribution Groups?

Figured it out for Distribution Groups; To test use this command in EMS; foreach ($mbx in (Get-DistributionGroup -resultsize unlimited)){ $addrs = $mbx.emailaddresses |? {$_.prefixstring -ne "x400"} Set-DistributionGroup $mbx -emailaddresses $addrs -whatif } Then to remove X400 addresses use this command in EMS; foreach ($mbx in (Get-DistributionGroup -resultsize unlimited)){ $addrs = $mbx.emailaddresses |? {$_.prefixstring -ne "x400"} Set-DistributionGroup $mbx -emailaddresses $addrs }
