Hi

I changed the 'ELCAssistantCalendarTaskRetentionEnabled' value to 0 in regedit so that the schedule does not apply to retention policy. in Exchange 2019 Onpremise

but, Now I want to move the schedule to archive at a different interval from retention policy.

I looked for a method with search-mailbox or several commands, but I decided not to use them.

I installed EWS API, An error occurred while the command was in progress.

///

C:\Windows\system32>$folder = [Microsoft.Exchange.WebService.Data.Folder]::Bind($service,$folderid)

Error: Microsoft.Exchange.WebServices.Data.ServiceRequestException: The request failed. The remote server returned an error: (401) Unauthorized

///

-summary

  1. How to Resolve Errors? (Is it possible in the way I'm proceeding?)
  2. How can I move a mailbox schedule(calendar) to archive? (It is rather good if there is a other better way from the above.)

Thanks

    Hi @ gihyun Park ,

    Do you want to move your calendar to the archive mailbox with different settings than in DPT?

    If this is the case, you can create a new retention tag that is moved to the archive, add it to the retention policy, then add this policy to the mailbox and apply it to the calendar folder.

    In addition, according to my search, the registry ELCAssistantCalendarTaskRetentionEnabled only works in the Exchange 2010 environment and does not work in Exchange 2016: Prevent Calendar items from archiving and deleting (Retention tags) - Microsoft Q&A

    Hello Gihyun,

    Thank you for your question and for reaching out with your question today.

    To resolve the "401 Unauthorized" error while using the EWS API to move a mailbox schedule/calendar to the archive, you need to ensure that the account running the script has the necessary permissions. Here are a few steps you can take to troubleshoot and resolve the issue:

    1. Confirm that the account running the script has the required permissions:
      • Make sure the account has the ApplicationImpersonation role assigned. This role allows the account to access and manipulate mailbox data on behalf of other users. You can assign this role using the Exchange Management Shell with the following command: 
        
     New-ManagementRoleAssignment -Name "ImpersonationRoleAssignment" -Role ApplicationImpersonation -User <AccountName>
      • Ensure that the account has sufficient permissions to access and modify the target mailbox and its calendar items.
    2. Verify the credentials used to connect to Exchange:
      • Double-check the username and password used in the script to connect to Exchange. Ensure they are correct and have the necessary privileges.
    3. Check if the Exchange Web Services (EWS) virtual directory is configured correctly:
      • Confirm that the EWS virtual directory is properly configured in Internet Information Services (IIS). Ensure that authentication methods are correctly set and that the virtual directory is accessible.
    4. Ensure the EWS URL is correct:
      • Verify that the URL used to connect to the Exchange Web Services is accurate. It should be in the format: https://<ExchangeServer>/EWS/Exchange.asmx.

    If the issue persists after performing these steps, it's recommended to review the EWS API documentation, consult with your Exchange administrator, or contact Microsoft support for further assistance.

    Regarding moving a mailbox schedule/calendar to the archive, using the EWS API is one way to achieve it. Alternatively, you can explore other methods such as using PowerShell cmdlets specific to Exchange Online (if applicable) or utilizing third-party tools that provide advanced mailbox management features.

    Remember to thoroughly test any scripts or changes in a non-production environment before implementing them in a live environment.
