Gapps mail migration to office 365

[Snapkop]

Anybody managed to do this the easy way?

Tried through the admin dashboard with imap settings but get a error message:
Data migrated:*1.515 MB ‎(1,588,110 bytes)‎*
Migration rate:*0 B ‎(0 bytes)‎*
Error:*MigrationMRSPermanentException: Error: This mailbox exceeded the maximum number of corrupt or missing items that were specified for this request.

I have the alternative of uploading the PST file but after reading the steps involved it seems very complicated.

Any one knows how I can get past the above error?

Good Morning, how many mailboxes?

And what is Gapps?

PST migration is not that complicated, that's how i did and will do my Office365 migrations. Takes time though depending on your site's upload speed and total size of your PSTs. If you have a site with fiber & good stable upload speeds then just collect your PSTs and go do the uploads from that office. Give it a shot

The Google Apps -> Office365 migration online also requires 2 step authentication to be turned on for each and every account.
It all depends on how many users and how big are the mailboxes. I did a relatively small migration (25 users, size ranging from 300mb - 8GB). I just exported the PST's from outlook (linked the gmail account) and then imported it into Outlook (O365 acc) and let it sync to the web. It takes a while to sync via outlook (multiple single items) but it took me 2 days in total and all was good.
I would do Kianm's route and upload the PST's via the admin portal.

Its one mail box around 9gb.

Poffle so you said I can import straight into outlook connected to the Exchange account? Then it will sync back to the cloud? I did not think about this. This is obviously much easier. I was going to attempt doing it through the admin portal but that had a whole bunch of complicated steps and terminology that I was not 100% comfortable with.

Yep exactly that. Export PST and Import and voila, it will start syncing easy as chips. 9GB will take long to upload, the average speed my outlook was uploading at was 1Mbs (and i had 8Mbs upload available)

Thanks poffle - not sure why I did not think about that. Fine if it takes long as long as I do not struggle and waste countless man hours on it.

poffle - one last question. Once I have done the import is it normal to for outlook to not show the mails in the different folders. I assume it syncing in the background. I can see the mails starting to appear on outlook.com. So in other words is outlook not usable until all uploaded?

I see the OST file has grown to the correct size and the folders appear but there is no mails in them except for my inbox.

Ahhhhh i ran into this problem on 1 of my PC's. So the folder type of all your user created folders is not 'Folder Containing Mail and Post Items', if you right click properties it'll probably show imap. Unfortunately i had a *** time with this one and was hoping it wouldn't happen on yours
To fix it: Create new folders and move your e-mails into the newly created folder. I created them on the outlook web interface and moved the mails there, it was tedious but only way i could.

Pretty much this: https://answers.microsoft.com/en-us...365-mail/235dd8cf-03ed-4018-a983-0f67a94b9c40

i tried all the other ways but did not work, only way was to re-create the folders and move the mail
Strange that out of 25 it only happened on 1 ... and now yours... maybe version differences or something like that

You champion - Thank you, you saved me a lot of time. I would have waited for the upload to finish and still have the same problem. Also realised the PST is half the size as gmail has the important folder that downloads the mail twice. Once into the normal folder and then again into important if it decided it was important.
