Hello Genius Peeps,

My name is Mehul Mehta i am working as a software developer in Nitech stainless Inc.com so my question is

Thought maybe I could turn here for some help! Does anyone know of a Powershell script I could run on our Exchange server for to the following:

1) We would initially want to clear all or current mobile devices from all the users

2) Then re-add their specific mobile device ID that we received from them to the ALLOW list

Is there some sort of .csv and script I can create to make this process fast?

We found the following scripts to remove all from ALLOW and to add to ALLOW

Clear all Allow
Set-CASMailbox -Identity username -ActiveSyncAllowedDeviceIDs $null

Add to Allow
Set-CASMailbox -Identity username -ActiveSyncAllowedDeviceIDs @{add='DeviceId'}

And maybe after running this script if theres also a quick way to show the results were made to the accounts? Using this command? Get-CASMailbox -Identity username | fl activesync*

    Hi @Nitech Inc ,

    Have you ever tried this: 

     Get-CASMailbox | Set-CASMailbox -ActiveSyncAllowedDeviceIDs $null  
      
 Import-Csv C:\list.csv |   
 ForEach{  
 try {  
 Set-CASMailbox -Identity $_.UserName -ActiveSyncAllowedDeviceIDs $_.DeviceId -ErrorAction Stop  
 Write-Output "Successfully Done $_" | Out-File "C:\added.csv" -Append  
 }  
 catch [System.Exception]   
 {  
 Write-Output "$_" | Out-File "c:\error.csv" -Append  
 }  
 Finally  
 {  
 }}

    Since your issue is same with this thread: https://learn.microsoft.com/en-us/answers/questions/359416/exchange-bulk-import-from-csv-file-to-remove-from.html
    I think you could check it and if that doesn't meet your requirement, please let me know.

    Best regards,
    Lou
