PST Imports - Security & Compliance - Or Outlook Imports
I have opened multiple tickets on this already as we are experiencing issues across multiple tenants. On 1/26 we performed a migration for two of our customers; switching them from our Exchange Server to Exchange Online. The process we used because we have over 2000 mailboxes was IMAP coupled with PST exports of calendars,contacts,notes, etc. It went perfectly; specifically the PST imports done through Security & Compliance.
On 2/9 we performed the same process for 4 more tenants and the PST Imports are stating its skipping items because they are "corrupted." Thinking it may have been a bad export from our Exchange 2013 server (using new-mailboxexportrequest) we redid the exports and those failed as well. Going back the previous two tenants we migrated on 1/26 we reused a PST file which was known to successfully import and spun up a temporary mailbox and tried the import again - it now states it is skipping items because they are "corrupted"
Going further we took several PST files and made sure they could be opened with Outlook and that we could see the items that are missing from the user's calendar. We then tried to do an Outlook PST import as well as a simple copy/paste and though the items show up on the user's calendar they disappear after about 15 minutes.
I have opened three tickets on this issue to hopefully get some traction. Two of the tickets I've received call backs. In both of those tickets (all listed below) I have explained the scale of the issue and emphasized the priority I am met with no response and on ticket 7380395 I was told "I get off in 7 minutes" to my explanation of how critical this is to get the issue identified so that we can notify our customers. For the Microsoft Quality control people reading this; listen to the audio because the call was "recorded for training purposes."
To the community could anyone that has recently performed PST Imports try another import using the same PST file to see if you get "Skiped / Corrupted items"? Screen shot of what I'm seeing is attached.

Having worked as support engineer, I know they have some policies around the number of tickets and they are always pressed to close them as soon as possible. And most of the time you end up with someone working for an outsourcing company, not a direct Microsoft employee, unless you pay from Premier. But that's the reality of it.
I've relayed your troubles to some of the Exchange folks, hope something will come out of it.

I reran the imports again using the same PST files and now I'm getting some successes. I went a little further and now I'm mapping out which server the user's mailbox is on. My bet is that there is some type of rolling fix being done behind the scenes without any acknowledgment of the issue. I will continue to retry failures and record which server they are on.

User Impact: Admins may be unable to migrate calendar items, and if migration is successful, the calendar may be missing items.
Thanks for the credit, but I barely did anything on this, just connected the dots. Many other MVPs have been complaining for a while now on that other issue I mentioned above, and putting some pressure on the MS folks. It seems the issues were indeed related, but hopefully it's all in the past now.
Craig, other have been seeing numerous issues with "corrupt" items when doing regular mailbox moves to O365 in the past few days. It might be a coincidence, but I have a suspicion the two issues are related. I'll try to ping few folks (and also relay your experience with support).
Thank you Vasil. I'm now up to 5 open tickets but it doesn't seem there is any urgency around the issue so any help would be greatly appreciated.
This probably won't make you feel any better, but I have been getting some excellent support from the SharePoint Online team for 3 tickets in the past 3 weeks.
