I’ve recently been looking into scenarios where organizations need to move mailboxes from Microsoft 365 to IMAP based email servers, and I noticed this is still a common requirement in many migrations. In most cases, the challenge is not just moving emails, but making sure everything like folder structure, old emails, and user data stays intact without creating too much disruption for users. From what I’ve seen, doing this manually can get very complex, especially when there are multiple mailboxes or large data volumes involved. That’s where migration tools usually come into the picture. Most tools simplify things by handling: 1. Secure connection to Microsoft 365 accounts 2. Bulk mailbox migration 3. Preserving folder hierarchy 4. Reducing downtime during the move 5. Avoiding duplicate data issues One thing I’ve noticed is that running a small pilot migration first always helps. It gives a clear idea of how the actual migration will behave before moving all users. Has anyone here worked on Office 365 to IMAP migration at scale? Would be good to know what approaches or tools worked best in your case and what challenges you faced during the process.Need to Restore PST Files to Office 365 Mailboxes - What's the Best Approach
Hey everyone, I have a task coming up where I need to restore several PST files back into Office 365 mailboxes. Haven't done this before at this scale and honestly not sure where to begin. I've looked at Microsoft's native import service through Purview but I have a few concerns: Some of the PST files are quite large — not sure how well it handles that I need to restore only specific folders for some users, not the entire PST I'm worried about data consistency after the restore Would prefer something that doesn't require too many admin roles or complex setup For those who have done PST to Office 365 restores — what approach worked best for you? Any tools, tips, or things to watch out for that you wish you knew before starting?Office 365 Mailbox Export to PST - Third Party Tools: What’s Your Experience?
Exporting Office 365 mailboxes to PST is still a common requirement in many Microsoft 365 environments, especially for backup, compliance, and migration scenarios. While Microsoft offers native options like Purview eDiscovery and Outlook export, many administrators also consider third-party tools when dealing with large mailboxes or bulk export requirements. In real-world scenarios, factors like speed, ease of use, permission handling, and consistency of exported data often influence the choice of tool. Some teams prefer native methods for compliance control, while others explore third-party solutions to simplify large-scale or repeated export tasks. For those working with Microsoft 365, what has your experience been with third-party PST export tools? Have they helped in your environment, or do you still rely mainly on Microsoft’s native options?Seamless Microsoft 365 Migration with Apps4Rent

need exchange se for hybrid environment
We have a hybrid Office 365 environment with an Exchange Server 2016 that no longer performs any role. It does not host any mailboxes and is not used as an SMTP relay. We would like to keep an Exchange installation solely for administrative purposes through the GUI. Questions: 1. Can we keep Exchange Server 2016 installed? 2. If we need to install Exchange Server Subscription Edition (SE), do we need licenses for this installation, considering that all our Office 365 licenses are Business licenses? Thank you.SharePoint Reporting using PnP PowerShell through Azure Automation
This article explains how to configure an Azure Automation runbook to execute PnP PowerShell and retrieve SharePoint site collection data across a Microsoft 365 tenant. This method is especially useful for tracking weekly changes within a SharePoint environment, such as during preparation for large initiatives like tenant-to-tenant migrations, and allows administrators to run scripts on a schedule without interactive sign-in. The solution uses Azure Automation, a managed cloud service that runs scripts in a headless environment. Runbooks behave like standard PowerShell scripts but execute non-interactively, meaning without prompts and output is available only after completion through job logs and output streams. 1. Create an Azure Automation Runbook To get started, you’ll need an Azure subscription to create the resources required for Azure Automation. While the Azure Portal interface may change over time, the underlying steps remain the same – follow the steps outlined below. a. Go to the Azure Portal and login with your Azure credentials b. Create a new Azure Automation Account using the Create a resource button and searching for Automation c. Fill out the details for the Azure Automation Account as desired and click Review + Create at the bottom left followed by clicking on Create on the review screen d. Once the resource has been created, click on Go to resource to open the Azure Automation resource 2. Configure the Azure Automation Account Now your Azure Automation Account has been created, proceed with the next paragraphs to configure it for using PnP PowerShell a. Add the PnP PowerShell module to the Azure Automation Account 1. Navigate to Modules which is located on the left side menu of the function app under the Shared Resources header. 2. Click on Add a module at the top of the screen IMPORTANT Currently, the only stable version of PnP PowerShell compatible with Azure Automation 7.2 runbooks is 2.12.0, as newer releases are not yet supported. Since the Browse from Gallery option only allows installation of the latest version, you must use the Upload from File option to upload a supported version instead. 3. Open up a PowerShell 7 console and execute the following command to download PnP PowerShell 2.12.0 Save-Module -Name PnP.PowerShell -RequiredVersion 2.12.0 -Path C:\temp 4. Using Windows File Explorer, go to the folder where you downloaded the PnP PowerShell package. You should see a folder called PnP.PowerShell in there. Right click on it and choose the option Compress to ZIP file. 5. Select Browse for file, Runtime version 7.2 (recommended) and click on the folder icon next to PowerShell module file and select the zipped up PnP.PowerShell.zip file generated in the previous step. 6. Click on Import to start the download and importing process. It could take up to 10 minutes for the import to complete. You can check the import status by changing the Module type filter to Custom. 7. Once it's done, it will show the status Available 3. Using Managed Identity for authentication The recommended approach is to use a managed identity in Azure to allow your Automation runbook to connect to Microsoft Graph and SharePoint Online via PnP PowerShell. This method lets you grant permissions directly to the runbook’s identity, eliminating the need for client secrets or certificates that could otherwise be exposed or misused. a. Enabling managed identity for an Azure Automation Runbook In your Azure Automation account, in the left menu, go to Identity under Account Settings Ensure you are on the System assigned tab and flip the switch for Status to On, if not already done Click the Save button and confirm your action in the dialog box that will be shown A new entry will now automatically be created in Entra ID for this app having the same name as your Automation account. This can be verified by going into Entra ID -> Enterprise Applications (under Manage). You may have to remove the default filters for your app to show. b. Assigning permissions to the managed identity Next, we shall use Graph PowerShell to assign permissions to the managed identity associated with the Automation account. 1. Using a CLI of your choice, run the following command. This will connect your PowerShell session to Microsoft Graph with AppRoleAssignment.ReadWrite.All permissions to read and modify app role assignments across your tenant. Connect-MgGraph -Scopes "AppRoleAssignment.ReadWrite.All" 2. Run the following commands to grant Sites.FullControl to the Graph API $GraphApp = Get-MgServicePrincipal -Filter "AppId eq '00000003-0000-0000-c000-000000000000'" $TargetResoruce = Get-MgServicePrincipal -filter "displayname eq 'pnppowershelldocumentationsample'" $Role = $GraphApp.AppRoles | Where-Object {$_.Value -eq "Sites.FullControl.All"} $AppRoleAssignment = @{} $AppRoleAssignment.Add("PrincipalId",$TargetResoruce.Id) $AppRoleAssignment.Add("ResourceId",$GraphApp.Id) $AppRoleAssignment.Add("AppRoleId",$Role.Id) $RoleAssignment = New-MgServicePrincipalAppRoleAssignment -ServicePrincipalId $TargetResoruce.Id -BodyParameter $AppRoleAssignment Note: AppId 00000003-0000-0000-c000-000000000000 is the standard identifier for the Graph API in Azure 3. Run the following commands to grant Sites.FullControl to the SharePoint Online API $SpApp = Get-MgServicePrincipal -Filter "AppId eq '00000003-0000-0ff1-ce00-000000000000'" $TargetResoruce = Get-MgServicePrincipal -filter "displayname eq 'pnppowershelldocumentationsample'" $Role = $SpApp.AppRoles | Where-Object Value -eq "Sites.FullControl.All" $AppRoleAssignment = @{} $AppRoleAssignment.Add("PrincipalId",$TargetResoruce.Id) $AppRoleAssignment.Add("ResourceId",$SpApp.Id) $AppRoleAssignment.Add("AppRoleId",$Role.Id) $RoleAssignment = New-MgServicePrincipalAppRoleAssignment -ServicePrincipalId $TargetResoruce.Id -BodyParameter $AppRoleAssignment Note: AppId 00000003-0000-0ff1-ce00-000000000000 is the standard identifier for the SharePoint Online API in Azure 4. Once permissions are granted, verify them in Entra ID (Entra ID -> Enterprise Applications (under Manage) -> Look up the app associated with your automation account (you may need to remove filters) -> Permissions (under Security) -> Verify permissions exist (as shown below) IMPORTANT API permission updates may take 10 minutes or more to propagate across Microsoft 365. During this time, scripts executed immediately against SharePoint can fail. If that happens, allow additional time for propagation and then retry the operation. 4. Create a Runbook We're now ready to create a Runbook in which your PnP PowerShell script will run. a. In the Azure Portal, in the left menu, click on Runbooks under Process Automation b. Click on Create a runbook at the top of the screen c. Give the Runbook a name, select the Runbook type PowerShell and for the Runtime version choose 7.2 (recommended) and click on Create at the bottom left. d. On the Edit PowerShell Runbook page, enter your PnP PowerShell code in the large white area, i.e. 5. Connect-PnPOnline 'https://tenant.sharepoint.com' -ManagedIdentity 7. Get-PnPWeb Once done, click on Save at the top of the screen and then on Test pane to test your Runbook. e. Click on Start to start testing the Runbook. It might take a few minutes for the Runbook to start. Once it's done, you will see the output of your PnP PowerShell script in the large black output section. 5. Generate a Tenant-Wide SharePoint Sites Report Next, we will execute a script to collect information for each SharePoint site in your tenant. The data will be exported to a CSV file and then uploaded to a designated folder within a SharePoint document library. This script uses the Get-PnPTenantSite cmdlet to gather the data. a. Open up the Runbook you had created and bring up the edit PowerShell page. Enter the following PnP PowerShell code in the large white area. You will need to update the values specific to your tenant. # Site info $adminUrl = "https://tenant-admin.sharepoint.com" $targetSiteUrl = "https://tenant.sharepoint.com/sites/M365Migration" $LibraryName = "Shared Documents" $TargetFolder = "Exports" # Timestamped file $TimeStamp = Get-Date -Format "yyyyMMdd_HHmm" $FileName = "ActiveSites_$TimeStamp.csv" # Create a safe temp folder in the runbook $TempFolder = $env:TEMP $TempPath = Join-Path -Path $TempFolder -ChildPath $FileName # Make sure the folder exists if (-not (Test-Path $TempFolder)) { New-Item -Path $TempFolder -ItemType Directory | Out-Null } # Connect to SharePoint Connect-PnPOnline $adminUrl -ManagedIdentity Write-Output "Connected to PnP" $sites = Get-PnPTenantSite -Detailed $sites | Select-Object ` Title, Url, Template, StorageUsageCurrent, StorageQuota, Owner, LockState, SharingCapability, TimeCreated, LastContentModifiedDate | Export-Csv -Path $TempPath -NoTypeInformation -Encoding UTF8 Write-Output "CSV created at $TempPath" Connect-PnPOnline $targetSiteUrl -ManagedIdentity # Upload the csv file Add-PnPFile -Path $TempPath -Folder "$LibraryName\$TargetFolder" Write-Output "File uploaded successfully to $LibraryName\$TargetFolder" # Close out Disconnect-PnPOnline Remove-Item $TempPath -Force b. Click on Save at the top of the screen and then on Test pane to test your Runbook c. Click on Start to start testing the Runbook d. After the run completes, check the specified document library for the CSV export and verify that a new report has been created successfully e. Close the code pane and click on Publish to publish this version of your runbook 6. Automate task to run on weekly schedule Next, we will explore how to automate this process to run weekly without requiring any user interaction. a. Create a schedule 1. In the Azure Portal, navigate to the Azure Automation account 2. Click on Schedules under Shared Resources 3. Click on Add a schedule 4. Enter name, description and start date. Select recurring to specify a schedule for job to run 5. Select week under recurrence and specify day of the week. Set an expiration date. Finally, click on Create. b. Link runbook to schedule 1. Open the runbook that you set up previously for your PnP PowerShell script 2. Click on Link to schedule 3. Select the schedule, parameters and run settings, and then click on OK 4. Verify schedule in the Runbook schedules page COMPLETE The script will now run automatically each week according to the defined schedule. At the specified date and time, a new report will be generated and uploaded to the document library without any manual steps. This means the process of collecting SharePoint site data across your tenant is now fully automated and requires no user interaction.New investments to accelerate your migration to Microsoft 365
Microsoft continues to power the digital transformation of customers with cutting edge, AI-enhanced productivity and collaboration tools. That's why we're excited to announce new investments to make it easier than ever to migrate your data to Microsoft 365 so you can take full advantage of these capabilities. Introducing the Slack to Teams Migration Tool When organizations explore adopting Microsoft 365, one of the first questions they ask is how they can migrate their data from their current platform to Microsoft 365. We have extensive experience and migration tools to support customers who want to move their emails, calendars, and files to Microsoft 365. But in the modern workplace, migrating chats and conversations can be just as important. That’s why we’re introducing the Slack to Teams Migration Tool from Microsoft. This tool is designed to migrate public and private channels from Slack to Teams, where your most critical conversations take place. The tool provides first class integration with Teams so migrated messages appear as if they’ve been posted directly in Teams with the original author and creation timestamp preserved. It also maintains the rich message content you’d expect, including message formatting, links and images, @-mentions, standard emojis, threaded replies, and more. File attachments are no problem as those are migrated too. And channel ownership and membership are preserved so that after the migration, participants can pick up right where they left off. The Slack to Teams Migration Tool from Microsoft has no licensing cost. Customers simply need to provide an Azure Blob Storage subscription and container to temporarily store their Slack export files while the migration is taking place. (Azure Blob Storage subscriptions have their own cost.) Once the migration is complete, the Azure Blob Storage subscription is no longer needed. This migration tool is a great option for customers interested in performing Slack migrations on their own, or as another tool for migration partners to help customers successfully transition to Microsoft 365. It's available now to all standard commercial customers worldwide. To learn more, see Introduction to the Slack to Teams Migration Tool. Future investments in the Slack to Teams Migration Tool These investments are an exciting start for this migration tool, but we’re not done yet. Over the coming year we plan to add even more features to the tool. Some of those features include: The ability to migrate group chats from Slack to Teams The ability to migrate direct messages (1-on-1 chats) from Slack to Teams The ability to migrate Slack canvas content into Microsoft Loop tabs in Teams The ability to provide an experience in Teams that will be familiar to users migrating from Slack The migration team would love to hear your feedback about any additional scenarios that are important to you. We operate preview programs for customers that want to engage closely with us to help shape the future investments in our migration tools.
