This script searches for OOF rules created by users using the Outlook rule-tab in the OOF assistant and deletes exisiting OOF rules.
In preparation to configure compliant Out-Of-Office (OFF) settings for users, any existing OOF rule needs to be deleted. The script will use either an exisiting Exchange Server EWS library or the Managed EWS library installed using the default file path.
This is the first of two scripts for the complete solution. Find the second script here.
The script access the mailbox rules using Exchange Web Services. Therefore the account executing the script either needs to have ApplicationImpersonation rights or full access to the user mailbox.
# EXAMPLE 1 # Find any existing OOF rule and write results to log file Remove-OOFRule # EXAMPLE 2 # Find and delete any existing OOF rules in all user mailboxes and write delete actions to log file Remove-OOFRule -Delete # EXAMPLE 3 # Find and delete any existing OOF rules for user SomeUser@varunagroup.de and write delete actions to log file Remove-OOFRule -Mailbox SomeUser@varunagroup.de -Delete

This script removes Active Directory objects for HealthMailboxes or SystemMailboxes in the Microsoft Exchange System Objects (MESO) container that do not have a homeMDB attribute set.
It is highly recommended to run the script with -WhatIf parameter to check objects first.
Information about accounts deleted or supposed to be deleted are written to a log file.
# EXAMPLE # Perform a WhatIf run in preparation to removing SystemMailboxes having an empty database attribute .\Remove-OrphanedMailboxAccounts.ps1 -SystemMailbox -WhatIf # EXAMPLE # Remove HealthMailbox(es) having an empty database attribute .\Remove-OrphanedMailboxAccounts.ps1 -HealthMailbox

Migrating legacy public folders (Exchange Server 2010 or older) to modern public folders (Exchange 2013 or newer / Office 365) requires a cleanup of public folders.
There are quite a lot of blog posts and tutorials available describing the general process of migrating legacy public folders to modern public folders.
First you have to identify all public folders having a backslash "\" as part of the public folder name.
Get-PublicFolderDatabase | ForEach {Get-PublicFolderStatistics -Server $_.Server | Where {$_.Name -like "*\*"}}
Just rename those public folders to a name without a backslash.
Another issue might prevent a successful public folder migration: Access Controll Lists (ACL)
This will be the case in public folder hierarchies that go back to the early days of Exchange and have never cleaned up properly during past Exchange migrations.
The cleanup any orphaned Active Directory accounts, run the following PowerShell script.
Get-PublicFolder "\" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | ?{$_.User -like "NT User:S-1-*"} | %{Remove-PublicFolderClientPermission -Identity $_.Identity -User $_.User -Access $_.AccessRights -Confirm:$false}
To cleanup just a single public folder, run the following PowerShell script.
Get-PublicFolder "\My Folder" -Recurse -ResultSize Unlimited | Get-PublicFolderClientPermission | ?{$_.User -like "NT User:S-1-*"} | %{Remove-PublicFolderClientPermission -Identity $_.Identity -User $_.User -Access $_.AccessRights -Confirm:$false}
It should be noted that most of the tutorials have been written using an Exchange Server lab environment with just a few legacy public folders. Therefore, some readers tend to beleive that you only need one modern public folder mailbox. That is not true. In a large legacy public folder infrastructure you will end up with a multiple public folder mailboxes. And the number of mailboxes required to serve the public folder hierarchy.
A larger public folder migration batch using 66 public folder mailboxes looks like this:
Get-MigrationUser -BatchID PFMigration | Get-MigrationUserStatistics | ft -AutoSize Identity Batch Status Items Synced Items Skipped -------- ----- ------ ------------ ------------- PFMailbox1 PFMigration Synced 91993 16 PFMailbox2 PFMigration Synced 103239 0 PFMailbox46 PFMigration Synced 35034 0 PFMailbox56 PFMigration Synced 22554 0 PFMailbox57 PFMigration Synced 20740 0 PFMailbox58 PFMigration Synced 20122 0 PFMailbox59 PFMigration Synced 7209 0 PFMailbox60 PFMigration Synced 104727 0 PFMailbox61 PFMigration Synced 23278 0 PFMailbox62 PFMigration Synced 9760 0 PFMailbox63 PFMigration Synced 9277 0 PFMailbox65 PFMigration Synced 5870 0 PFMailbox64 PFMigration Synced 5639 0 PFMailbox66 PFMigration Synced 21261 0 PFMailbox50 PFMigration Synced 27889 0 PFMailbox52 PFMigration Synced 14063 0 PFMailbox47 PFMigration Synced 29476 0 PFMailbox54 PFMigration Synced 24283 0 PFMailbox55 PFMigration Synced 4646 0 PFMailbox51 PFMigration Synced 59943 0 PFMailbox53 PFMigration Synced 30052 0 PFMailbox49 PFMigration Synced 22746 0 PFMailbox48 PFMigration Synced 16941 0 PFMailbox18 PFMigration Synced 34307 0 PFMailbox19 PFMigration Synced 4523 0 PFMailbox11 PFMigration Synced 100409 0 PFMailbox6 PFMigration Synced 116655 0 PFMailbox4 PFMigration Synced 55240 5 PFMailbox12 PFMigration Synced 37790 0 PFMailbox3 PFMigration Synced 113842 2 PFMailbox22 PFMigration Synced 46416 0 PFMailbox23 PFMigration Synced 37387 0 PFMailbox13 PFMigration Synced 231845 1 PFMailbox7 PFMigration Synced 82859 0 PFMailbox20 PFMigration Synced 65818 0 PFMailbox21 PFMigration Synced 32270 0 PFMailbox9 PFMigration Synced 46609 0 PFMailbox14 PFMigration Synced 30637 0 PFMailbox38 PFMigration Synced 246428 1 PFMailbox43 PFMigration Synced 101837 0 PFMailbox45 PFMigration Synced 157571 0 PFMailbox44 PFMigration Synced 61763 0 PFMailbox40 PFMigration Synced 70637 1 PFMailbox41 PFMigration Synced 143042 0 PFMailbox42 PFMigration Synced 81254 0 PFMailbox39 PFMigration Synced 68876 2 PFMailbox15 PFMigration Synced 58221 0 PFMailbox27 PFMigration Synced 28065 0 PFMailbox24 PFMigration Synced 31869 1 PFMailbox5 PFMigration Synced 64125 0 PFMailbox30 PFMigration Synced 72938 1 PFMailbox33 PFMigration Synced 32545 1 PFMailbox31 PFMigration Synced 93782 0 PFMailbox32 PFMigration Synced 28743 0 PFMailbox25 PFMigration Synced 100794 0 PFMailbox26 PFMigration Synced 35412 0 PFMailbox28 PFMigration Synced 27003 0 PFMailbox29 PFMigration Synced 80510 0 PFMailbox17 PFMigration Synced 97952 1 PFMailbox8 PFMigration Synced 18601 0 PFMailbox34 PFMigration Synced 87150 0 PFMailbox35 PFMigration Synced 31531 0 PFMailbox36 PFMigration Synced 37979 0 PFMailbox37 PFMigration Synced 95770 0 PFMailbox10 PFMigration Synced 14193 0 PFMailbox16 PFMigration Synced 64323 1

This script removes the proxy address(es) for a selected protocol from mail enabled public folders.
Any proxy address with a given protocol is removed from the proxy addresses list.
The script can fix the alias of mail enabled public folders as well. The code used is based opon a blog post by Shay Levy.
# EXAMPLE 1 # Check mail enabled public folders for proxy addresses having "MS:" as a protocol type. # Do not remove and update addresses, but log found addresses to RemovedAddresses.txt .\Clean-MailEnabledPublicFolders.ps1 -ProtocolToRemove "MS:*" # EXAMPLE 2 # Check mail enabled public folders for proxy addresses having "MS:" as a protocol type. # Remove and update addresses and log found addresses to RemovedAddresses.txt .\Clean-MailEnabledPublicFolders.ps1 -ProtocolToRemove "MS:*" -UpdateAddresses
This Powershell script has been optimized using the ISESteroids™ add-on. Learn more about ISESteroids™ here.
This script deletes user from the NoSpamProxy NoSpamProxyAddressSynchronization database table [Usermanagement].[User] table that have not been removed by the NoSpamProxy Active Directory synchronization job.
The script was developed due to a process flaw in how Active Directory accounts are handled as part of a leaver process. So this script does not fix a software bug, but a process glitch.
Due to the Active Directory account process the accounts still exist in Active Directory and are synchronized to the NoSpamProxyAddressSynchronization database.
When executed without the -Delete parameter all identified users are wirtten the log file only.
# EXAMPLE 1 # Check for Active Directory existance of all users stored in NoSpamProxy database. Do NOT delete any users from the database. .\Remove-NspUsers.ps1 # EXAMPLE 2 # Delete users from NoSpamProxy database hosted on SQL instance MYNSPSERVER\SQLEXPRESS that do NOT exist in Active Directory. .\Remove-NspUsers.ps1 -Delete -SqlServerInstance MYNSPSERVER\SQLEXPRESS
When you delete a mailbox or an Active Directory account, the soft-deleted or disconnected mailbox won't show up in the list of disconnected mailboxes immediately. The mailbox status is updated as part of a mailbox store maintenance task.
When you query a mailbox database for disconnected mailboxes you will find a mailbox having the DisconnectReason and DisconnectDate attribute empty.
# Query the mailbox using the original user display name Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisplayName -eq "LASTNAME, FIRSTNAME" } | fl DisconnectReason,DisconnectDate,MailboxGuid,Database # Use wildcards if the correct display name is unknown Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisplayName -like "*LASTNAME*" } | fl DisconnectReason,DisconnectDate,MailboxGuid,Database DisconnectReason : DisconnectDate : MailboxGuid : a04a8aab-c360-406b-a194-8c290d56668b Database : MBXDB34
You can find disonnected mailboxes by
The following PowerShell cmdlet updates the mailbox state of a single mailbox using the MailboxGuid as an identifier.
Update-StoreMailboxState -Database MBXDB34 -Identity a04a8aab-c360-406b-a194-8c290d56668b
After updating the mailbox state the DisconnectReason and DisconnectDate attributes are properly set.
Get-MailboxDatabase | Get-MailboxStatistics | Where { $_.DisplayName -eq "LASTNAME, FIRSTNAME" } | fl DisconnectReason,DisconnectDate,MailboxGuid,Database DisconnectReason : Disabled DisconnectDate : 01.01.2017 15:02:59 MailboxGuid : a04a8aab-c360-406b-a194-8c290d56668b Database : MBXDB34
The disconnected mailbox is now visible in Exchange Administrative Center (EAC) and can be reconnected using EAC or Exchange Management Shell.
By default a disconnected mailbox is supposed to be connected it's original account having a matching LegacyExchangeDN attribute. Connecting the mailbox to a different Active Directory account requires the use of the AllowLegacyDNMismatch parameter.
# Connect a mailbox to the original AD account having a matching LegacyExchangeDN Connect-Mailbox -Database MBXDB34 -Identity "Doe, John" # Connect a mailbox to a different AD account Connect-Mailbox -Database MBXDB34 -Identity "Doe, John" -User "Jane Doe" -AllowLegacyDNMismatch
Examples for room and shared mailboxes are described in the Connect-Mailbox documentation.
This script exports all mailbox folder permissions for mailboxes of the type UserMailbox. This is useful for documentation purposes prior to migration.
The permissions are exported to a local CSV file.
The script is intended to run from within an active Exchange 2013/2016 Management Shell session.
Gather mailbox folder permission data for a large number of mailboxes takes some time.
# Export mailbox permissions to export.csv .\Get-MailboxPermissionsReport-ps1 -CsvFileName export.csv
