Potential Office365 (Exchange Online) Throttling Issue

@jaredbusch said in Potential Office365 (Exchange Online) Throttling Issue:
Outlook has always had this with size, if not message count. but if they match you should be good I would assume.
They never match exactly, though, which is the issue.
You can change Outlook to display the number of items, but that is also very manual as you have to do it for every folder.
I basically randomly write down folders, and check through them. I figure if 20 out of 40 are correct, they all should be.
I think Exchange must calculate storage differently than MDaemon and the PST. Not surprising. Maybe it compresses it by default.
I've never actually administered Exchange, so don't know.

Trying the PST import method. Honestly, it isn't much better.
Have a 3.28 GB PST upload to Office365 already. Started the import at 2:03. It is now 6 hours later and it is only 59% done. So this seems like it might even be SLOWER than the other way.
WTH, Microsoft. Why do you make it so hard to switch to your product?

I am still amazed at how long it has taken you, I am not sure from what email system you are coming from but usually I do importa initially a month or 2 weeks before and then do deltas every week with the Builtin migration tool.

I guess my mistake is expecting it to happen it like every other file transfer would happen.
I mean, the upload of the PST to Azure went almost full ISP speed of 65 Mbps. Why the F do they import the data at .5GB an hour or less. Just makes no sense why they would want such a delay in allowing people to switch over to their system.

IMAP
They have a built in migration as well for that:

@bigbear said that is a disaster, and that's about the feel I got from it from reading stories online, as well.
We can argue the point all we want, but the thing is, there IS an easy way to do this. It's just the Microsoft cripples it for some reason.

I like either the Azure method or the MigrationWiz. With the latter you can migrate ahead of time and sync up after the switch or do a dial tone migration if you don’t have the time to plan.
Azure is more work but when migration hundreds of large mailboxes it’s better than the outlook import method.
Soemthing to note, when you migrate a premise exchange server you get full speed upload automatically from MS.
Seems like with the limits raised we complete Terrabytes of mail migrations over a weekend without anyone left behind. I’ll have to pay attention next weekend on what speeds were seeing in live migration.
-
They are throttling. I just went through a 100 mailbox migration and a user with a 15 GB mailbox took 3 days. I have a 150/150 Mbps dedicated fiber circuit.

I was in hybrid mode and it still took a long time.

I guess, I was just trying to give more options but patience seems to be the answer.

Yeah this is basically what I am saying.
Plus these "higher speeds" they discuss are with concurrent users.
So that could be why. If you happen to have 100 users and they are all 5GB mailboxes you will complete over a weekend.
You have 100 users with 20GB mailboxes, you are in for a world of hurt.

Definitely completing multiple 20Gb mailboxes over a weekend.

I did not have that experience, have done it twice.

Maybe they are throttling it more.
My next step with be the IMAP product you mentioned. We'll see where we get with that.

BTW:
As a followup to this ... thanks to all who recommended MigrationWiz by BitTitan. Great product, works awesome (and relatively quick) ... and their support is live and incredible.
TWO BIG THUMBS UP!!!!!
Just wish I had learned about them at the beginning of this whole ordeal.
