Script for Teams-Chat backup
Sometimes it is necessary to save the chat history of a Teams-Channel. I wrote a simple script, where you can select the needed Team(s) and outputting the Chat-Content to a html File. If there are any comments, I'm open for suggestions. Here is the Script: #Install-Module -Name SharePointPnPPowerShellOnline $SecurityScope = @("Group.Read.All") Connect-PnPOnline -Scopes $SecurityScope $PnPGraphAccessToken = Get-PnPGraphAccessToken ,$Headers = @{ "Content-Type" = "application/json" Authorization = "Bearer $PnPGraphAccessToken" } $Date = Get-Date -Format "dd.MM.yyyy, HH:mm" $DOCTYPE = "<!DOCTYPE html PUBLIC '-//W3C//DTD XHTML 1.0 Strict//EN' 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd'><html xmlns='http://www.w3.org/1999/xhtml'>" $Style ="<style>table {border-collapse: collapse; width:100%;} table th {text-align:left; background-color: #004C99; color:#fff; padding: 4px 30px 4px 8px;} table td {border: 1px solid #004C99; padding: 4px 8px;} td {background-color: #DDE5FF}</style>" $Head = "<head><title>Backup: Teams-Chat</title></head>" $Body = "<body><div style='width: 100%;'><table><tr><th style='text-align:center'><h1>Backup: Teams-Chat from $Date</h1></th></tr></table>" $Table_body = "<div style='width: 100%;'><table><tr><th>TimeStamp</th><th>User Name</th><th>Message</th></tr>" $Content ="" $Footer = "</body>" $response_teams = Invoke-RestMethod -Uri "https://graph.microsoft.com/beta/groups" -Method Get -Headers $Headers -UseBasicParsing $response_teams.value | Where-Object {$_.groupTypes -eq "Unified"} | Select-Object -Property displayName, ID | Out-GridView -PassThru -Title 'Which Team-Chat do you want to backup?' | ForEach-Object { $Team_ID = $_.ID $Team_displayName = $_.displayName Write-Progress -Activity "Bckup Team Chat Mesasages" -Status "Get Team: $($Team_displayName)" Start-Sleep -Milliseconds 50 $Content += "</br></br><hr><h2>Team: " + $Team_displayName + "</h2>" $response_channels = Invoke-RestMethod -Uri "https://graph.microsoft.com/beta/teams/$Team_ID/channels" -Method Get -Headers $Headers -UseBasicParsing $response_channels.value | Select-Object -Property ID, displayName | ForEach-Object { $Channel_ID = $_.ID $Channel_displayName = $_.displayName Write-Progress -Activity "Bckup Team Chat Mesasages" -Status "Get Channel: $($Channel_displayName)" Start-Sleep -Milliseconds 50 $Content += "<h3>Channel: " + $Channel_displayName + "</h3>" $response_messages = Invoke-RestMethod -Uri "https://graph.microsoft.com/beta/teams/$Team_ID/channels/$Channel_ID/messages" -Method Get -Headers $Headers -UseBasicParsing $response_messages.value | Select-Object -Property ID, createdDateTime, from | ForEach-Object { $Message_ID = $_.ID $Message_TimeStamp = $_.createdDateTime $Message_from = $_.from $response_content = Invoke-RestMethod -Uri "https://graph.microsoft.com/beta/teams/$Team_ID/channels/$Channel_ID/messages/$Message_ID" -Method Get -Headers $Headers -UseBasicParsing Write-Progress -Activity "Bckup Team Chat Mesasages" -Status "Get Team: $($Team_displayName), Gett Message-ID: $($Message_ID), from Channel: $($Channel_displayName)" Start-Sleep -Milliseconds 50 $Content += $Table_body + "<td>" + $Message_TimeStamp + "</td><td style='width: 10%;'>" + $Message_from.user.displayName + "</td><td style='width: 75%;'>" + $response_content.body.content + $response_content.attachments.id + "</td></table></div>" $response_Reply = Invoke-RestMethod -Uri "https://graph.microsoft.com/beta/teams/$Team_ID/channels/$Channel_ID/messages/$Message_ID/replies" -Method Get -Headers $Headers -UseBasicParsing $response_Reply.value | Select-Object -Property ID, createdDateTime, from | ForEach-Object { $Reply_ID = $_.ID $Reply_TimeStamp= $_.createdDateTime $Reply_from = $_.from $response_Reply = Invoke-RestMethod -Uri "https://graph.microsoft.com/beta/teams/$Team_ID/channels/$Channel_ID/messages/$Message_ID/replies/$Reply_ID" -Method Get -Headers $Headers -UseBasicParsing Write-Progress -Activity "Bckup Team Chat Mesasages" -Status "Gett Reply-Message-ID: $($Reply_ID)" Start-Sleep -Milliseconds 50 ForEach-Object { $Content += $Table_body + "<td>" + $Reply_TimeStamp + "</td><td style='width: 10%;'>" + $Reply_from.user.displayName + "</td><td style='width: 75%;'>" + $response_Reply.body.content + $response_Reply.attachments.id + $response_Reply.attachments.name + "</td></table></div>" } } } } } $DOCTYPE + $Style + $Head + $Body + $Content + $Footer | Out-File -FilePath "C:\Backup.html" & "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" "C:\Backup.html"How to automate adding tags to multiple team members at once using PowerShell
I see that there is no way to ease the job of adding a tag to multiple users at the same time without having to look for the user in the edit tag window, so if you have a large list of team members and you want to add the tag to a lot of them or all, it is a little tedious, so exploring the API we can do this, sharing here in case anyone needs this https://get-itips.capazero.net/posts/Add-TagsToUsers

Could someone show me how I would take this script and run it against a list of users? Currently it is only designed to run against the user which is authenticated. I understand the on behalf permissions in Office 365 has to be granted, I just want to know how can I run this against a list of users, perhaps in a text file? function Get-TeamsMeetingsFolder{ param( [Parameter(Position = 1, Mandatory = $true)] [string]$MailboxName, [Parameter(Position = 2, Mandatory = $false)] [string]$AccessToken, [Parameter(Position = 3, Mandatory = $false)] [string]$url, [Parameter(Position = 4, Mandatory = $false)] [switch]$useImpersonation, [Parameter(Position = 5, Mandatory = $false)] [switch]$basicAuth, [Parameter(Position = 6, Mandatory = $false)] [System.Management.Automation.PSCredential]$Credentials, [Parameter(Position =7, Mandatory = $false) ] [Microsoft.Exchange.WebServices.Data.ExchangeService]$service ) Process { if($service -eq $null){ if ($basicAuth.IsPresent) { if (!$Credentials) { $Credentials = Get-Credential } $service = Connect-Exchange -MailboxName $MailboxName -url $url -basicAuth -Credentials $Credentials } else { $service = Connect-EXCExchange -MailboxName $MailboxName -ModernAuth #-AccessToken $AccessToken } $service.HttpHeaders.Add("X-AnchorMailbox", $MailboxName); if ($useImpersonation.IsPresent) { $service.ImpersonatedUserId = new-object Microsoft.Exchange.WebServices.Data.ImpersonatedUserId([Microsoft.Exchange.WebServices.Data.ConnectingIdType]::SmtpAddress, $MailboxName) } } $folderid= new-object Microsoft.Exchange.WebServices.Data.FolderId([Microsoft.Exchange.WebServices.Data.WellKnownFolderName]::Root,$MailboxName) $TeamMeetingsFolderEntryId = new-object Microsoft.Exchange.WebServices.Data.ExtendedPropertyDefinition([System.Guid]::Parse("{07857F3C-AC6C-426B-8A8D-D1F7EA59F3C8}"), "TeamsMeetingsFolderEntryId", [Microsoft.Exchange.WebServices.Data.MapiPropertyType]::Binary); $psPropset= new-object Microsoft.Exchange.WebServices.Data.PropertySet([Microsoft.Exchange.WebServices.Data.BasePropertySet]::FirstClassProperties) $psPropset.Add($TeamMeetingsFolderEntryId) $RootFolder = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$folderid,$psPropset) $FolderIdVal = $null $TeamsMeetingFolder = $null if ($RootFolder.TryGetProperty($TeamMeetingsFolderEntryId,[ref]$FolderIdVal)) { $TeamMeetingFolderId= new-object Microsoft.Exchange.WebServices.Data.FolderId((ConvertId -HexId ([System.BitConverter]::ToString($FolderIdVal).Replace("-","")) -service $service)) $TeamsMeetingFolder = [Microsoft.Exchange.WebServices.Data.Folder]::Bind($service,$TeamMeetingFolderId); } return $TeamsMeetingFolder } }
