Just can't get enough of IT

This blog is about mostly anything in IT. But the primary focuses are Microsoft Technologies like Exchange, Office 365, Azure and Cloud Security.

When you delete a public folder using a legacy Outlook client, you can easily restore the deleted folder and it's content using the Recover Deleted Items function. 

Due to a fancy trick implemented in Outlook 2013 and Outlook 2016 the recovered folder will not be recovered using it's full name.

This phenomenon has been verified with Exchange On-Premises and Exchange Online on the server side and Outlook 2013/2016 and Outlook 365 ProPlus.

The following example uses public folders in Exchange Online and Outlook 365 ProPlus.

Example

In this example I will delete and recover a public folder named My Public Folder.

Public folder hierarchy before deletion

After deletion of My Public Folder and it's content, I need to select the original parent folder and click the Recover Deleted Items button in the button bar.

Select original parent folder

Recover Deleted Items

The Recover Deleted Items dialogue opens and we select the deleted item for recovery. The dialogue displays the original name of the deleted folder.

Recover Deleted Items (DE)

After recovering the deleted folder the folder is recovered with the first character only.

Recovered public folder with first character only

That's an annoying result in regards to customer self-care when users restore deleted items on their own behalf.

But wait, there is a solution available.

Solution

The solution requires today's primary administrative tool available: PowerShell.

Step 1

Get an overview of public folders currently located in the public folder dumpster

Get-PublicFolder –Identity “\NON_IPM_SUBTREE” –Recurse 

Name             Parent Path
----             -----------
NON_IPM_SUBTREE
[...]
My Public Folder \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-3...
Sub Folder 1     \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-3...
Sub Folder 2     \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-3...
[...]

 

Step 2

Export the list of public folders currently located in the public folder dumpster and find the identity of the deleted public folder you want to recover

Get-PublicFolder –Identity “\NON_IPM_SUBTREE” –Recurse  | fl | Out-File D:\TMP\publicfolderdumpster.txt

publicfolderdumpster.txt excerpt:


RunspaceId                     : 6ce9588e-829b-4592-aedc-85f9a2e2c963
Identity                       : \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-366a-4e0
                                 9-81fe-ea576ec7a6f7\My Public Folder
Name                           : My Public Folder
MailEnabled                    : False
MailRecipientGuid              : 
ParentPath                     : \NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-366a-4e0
                                 9-81fe-ea576ec7a6f7

Step 3

Recover the deleted public folder to the correct parent target folder

Set-PublicFolder –Identity "\NON_IPM_SUBTREE\DUMPSTER_ROOT\DUMPSTER_EXTEND\RESERVED_1\RESERVED_1\65722859-366a-4e09-81fe-ea576ec7a6f7\My Public Folder" –Path “\TestFolders” –Verbose

As a result the public folder is recovered with it's original name.

Notes

There are some other things to consider when recovering deleted modern public folders.

Public folders originally located in the hierarchy root are always recovered to the public folder mailbox holding the primary hierarchy. 

Public folders originally located in the hierarchy root will replace the permissions of child public folders when restored. 

More on these default restore behaviours can be read here.

Nevertheless, enjoy modern public folders.

Exchange Server 2013Exchange Server 2016Description

This script imports multiple PST files located in a single directory into a user mailbox or a user mailbox archive. 

Due to some filename limitations of the New-MailboxImportRequest cmdlet in reagards to the UNC path, the PST filenames are sanitized. Any unsupported (unwanted) character is removed. You can modify the replacement function as needed. This might be necessary as the PST filenames can be used as target folder names during import.

Original filenames:

Filenames before renaming

Renamed filenames:

Filenames after renaming

When using the FilenameAsTargetFolder switch each PST file is imported into a separate target folder.

PST filenames used as target folder

After successfully importing a PST file, the PST can optionally be renamed to .imported. This simplifies a re-run of the script in the case that you a lot of PST files for a user or a large number of files as part of archive solution offboarding process.

NOTE:
This script utilizes the GlobalFunctions PowerShell module for logging. Please prepare your system for the use of the GlobalFunctions module first.

Steps performed:

  1. Sanitize PST filenames
  2. Create new mailbox import request
  3. Monitor status of created import request
    1. When still running, continue monitoring status
    2. When successfully finished, save import request statistics report to log file and continue with next PST
    3. Rename the imported PST file to .imported
    4. When aborted, continue with next PST or exit script

Troubleshooting Outlook connectivity issues with Office 365 is tricky. Administrators can use two valuable tools provided by Microsoft to identify and even fix client related connectivity issues.

1. Outlook Account Test Page

Start with the Outlook account problems test page in the Office 365 portal. You need to log on as the Office 365 user having issues.

SARA Server

The site tests for the following:

  • You cannot create an Outlook profile or you are asked for your password repeatedly when creating one.
  • You cannot connect to your mailbox or receive an error that a mailbox cannot be found.
  • You are getting invalid license errors or messages that Office cannot verify the license.

If no issues are identified after you've logged on to Office 365, move to the next step.

2. Support and Recovery Assistant

The Microsoft Support and Recovery Assistant (SARA) for Office 365 is click to run tool that is installed and executed locally.

Support and Recovery Assistant (SARA)

These two tools fix most of the Outlook connectivity issues you are facing as an Office 365 administrator.
