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?Planning to Migrate OST Files to Microsoft 365 - Need Some Guidance Before I Start
Hey folks, I have a task coming up where I need to migrate OST files into Office 365 mailboxes. A few of the OST files I'm dealing with are orphaned or corrupted which is making me a bit nervous about the whole process. A couple of things I'm unsure about: How to handle OST files that are no longer linked to an active profile Whether corrupted OST files can still be migrated to Office 365 without major data loss Best way to verify data integrity after migration Haven't started yet and want to make sure I'm going in the right direction before I begin. Has anyone migrated corrupted or orphaned OST files to Office 365? What approach worked best for you?Moving Office 365 Mailboxes to IMAP Servers - What’s the Best Approach
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.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?
Disable incessant nagware popups
I don't know about everyone else, but I am sick and tired of the nagware pop ups in Word, Excel, PowerPoint, Outlook, etc. Every single product harasses me with pop ups trying to tell me "hey, did you know this feature was here?", "you can do this if you click that", "let me hold your hand through using products you've used for decades even though you don't want daddy Microslop to do that". This is a prime example. I keep getting the same ones again and again and again and everything I've read indicates they should only appear once. But they don't. They keep coming back like a psychotic stalker ex who wants alimony even though you were never married. How do I get this nagware to stop?!Microsoft 365 Backup Launches File-Level Restore
The Microsoft 365 Backup solution will soon be able to restore individual files and folders instead of complete sites. That’s a welcome upgrade to restore capabilities to cover situations like the inadvertent deletion of a file. It’s a wonder why Microsoft didn’t make more about this capability when they celebrated SharePoint’s 25th anniversary last week when they discussed departmental billing for Microsoft 365 Backup. https://office365itpros.com/2026/03/11/microsoft-365-backup-file-restore/
How to restore a single file deleted 6 months ago - using M365 Backup?
My friend's company uses Sharepoint Online, but relevant folders are synced to their OneDrive so they manage everything in File Explorer. I have Microsoft 365 Backup enabled on their Sharepoint site. This company has all the parent folders in "Site Contents". These folders include Sales, HR, Clients, etc. I need to restore a single file out of Sales but it appears I need to restore the entire site first, sync the Sales folder from the site ending in /R0 to my OneDrive, then copy/paste from my File Explorer. Yes, I am a NOOB in Sharepoint. What's the right way to grab this file? And if it's ditching M365 Backup, then that's what I'll do, but I still need to get this file.
