If they would just open the pipe up for a few days for me, this would be so simple.
BTW are you using Outlook 2016? Just curious because of PST file limits in older versions.
I have always just setup the new user, run a migrationwiz pass for the last 2 weeks, contacts, calendar etc, let the user into their new 365 mailbox then started the full pass migration. This is what MS refers to as a "dial tone" migration. Then I run another pass a couple weeks later before shutting down the old server or services.
I would imagine the upload limits to be DoS Security best practices of some sort.
How long does the actual migration take? The actual file copy, I mean.
In theory, if what I am doing works, it's not the end of the world if I do it on their actual machine.
It's the fact I staged it that is causing the problem.

If you are talking about Outlook import I have never seen one complete over 15GB. Left one out there for 2 weeks.
If you are talking about Migrationwiz its all server to server and doesn't affect the user. You could manually import the last few weeks and all contact, setup their new Outlook and let the import run overnight. Outlook should only be caching 90 days or so of email anyway.
Are you going to configure an archiving policy?

Shhhhhhhh! It's working its way through nicely. Just slooooowwwwww.

Right, but according to that link, MS throttles 3rd party migrations to .1 to .3 GB per hour. So it would take forever, not overnight. You've seen large mailboxes import using Migrationwiz overnight?
Are you going to configure an archiving policy?
You mean to filter messages into the in-place archive?
No.

We always open a ticket to request a temp lift on EWSLimits. I believe this has already been lifted for you per your comment above, but per my comment I don't believe the support guys know what you are talking about. And the EWS limits being increased has never made an Outlook import for a large mailbox go faster or finish for me. But will be interesting to see if it does for you. I just wouldnt bet my lunch on it.

How long does that take to go into effect once you request it?

So you are saying you saw the same thing as me .. they said the took off the throttling, but nothing actually changes...

We always do it a week or so in advance and they give you 90 days. As we are discussing this I am curious as to whether you could run powershell command Get-ThrottlingPolicy to see if its working on EWS...

They dont remove throttling but they increase the limits per your specific, kindly worded request
You would want to ask for throttling limits to be increased for 60 or 90 days in a new ticket and we always include these details (which came from MigrationWiz I think)
I always ask for xx (number of users) to be set for concurrent migration as well in the ticket.
EwsCutoffBalance = Unlimited
EwsMaxSubscriptions = xx
EwsMaxBurst = Unlimited
EwsMaxConcurrency = xx
EwsRechargeRate = UnlimitedAnd it did not seem to help Outlook import on a specific 15GB mailbox I recall, I had a dozen larger ones that also needed to complete so I moved on to MigrationWiz on that particular project.

A side note, per MigrationWiz support docs, you can no longer use Get-ThrottlingPolicy powershell commands against EWS/365
I had never thought of trying it before now... -

I had never thought of trying it before now...Yeah I noticed that when I first starting Googling for this issue.
I spoke to the tech again just now. He said that his original request was for 15 days. And then a second tech asked for 30 days. He said they are very finicky about this, and he thought maybe going to 2 days would work, so he is going to try that, and also speak to the next level guys.
He did say we can use the PST option, and it seems to always be reliable. But that if they can get this throttle turned off temporarily, that THAT would be the best method.
Updates to come...

So basically, no one knows how to submit this request internally.

Uh, yeah, that would be a good way of saying that.

Considering the latest update is .. that after talking to the next level up, it turns out this CANNOT be done, except possibly for large migrations. (Which makes no sense, so is probably not true.)
I would actually update this to no one over there knows what they are doing, actually.
They recommended going with the PST upload, which I am testing now.
I uploaded a 647K KB PST file to the system. It said it would import it, though it only said it was 550MB. So I am wondering if it is some sort of compression thing, some sort of PST vs. message storage thing, or just a mess up on their end.
Once the file was uploaded, I hit IMPORT. That was at 3:02. It's now 3:38 and this is what I see. I wonder if this is going to be a typical Microsoft update. Stay at 0% for an hour then say it is done.

You uploaded a file that was .6 MB and now MS is telling you it's 550 MB? damn, that's some expansion.

647K KB (647,000 KB) is .6 MB?

It ended up taking about 70 minutes, but it completed. Now I have to look at the file and compare folders and see if everything copied over, especially since the PST file sizes were reported as different.

Was that the test upload or the 20Gb file

The test upload.
I am checking through it now ... it seems to have worked.
I got thrown off by the stupid filter setting Outlook has ... had to go through the folders and de-select that, but it seems to have gotten them all.

Or right click properties and check the file count and stuff?
