2. `Copy Secure URL and secure storage account key

To get the Azure secure storage account key and URL you will have to go back to the Office 365 portal and then click on Import tab on the left pane

Then click on the Key sign below

When you click on it, you will be able to retrieve the key and the URL by clicking on Copy Key and URL .

The copy is pretty long and you’ll have to notice that sometimes you might get confused and copy only the appearing portion of it in the field… if you do so and copied that in the Azcopy command or Azure storage explorer you might get an error …

In some cases, we need to check the status of the last operation and it can be useful for troubleshooting as well. We can use the same cmdlet that we have been using and adding the switch –report to get the historical information of the previous run, as shown in Figure 04.

Cleaning-up the Requests...

By default, each Mailbox Import/Export request will have the name MailboxExportX, where X is a number starting from 1 to 9 and after that the cmdlet will ask you to name your new requests.

Bear in mind that we are going to focus on the Export process, however you can replace the Export string on all cmdlets below to Import and get the same results.

Frequently asked questions

Q. What happens to my data?

• Import PST file into your Office 365 mailbox(es)

1. Open Outlook with your Office 365 account

2. File >>> Open >>> Open Outlook Date File

3. Then you can choose the certain PST file which you want to import and add it into your Outlook

4. When you add the certain PST file into your PST file, you can see it from the mailbox list in your Outlook

5. Then you can simply choose the emails which you want to Copy –Paste (Or directly drag your emails into your Office 365 account)  to your Office 365 account

I'll set Outlook off-line (to force it to use the local cached copy) and begin the export for that user.  I'll move on to the next PC and do the same thing, till I've got all of them exporting.  This should require no Internet bandwidth, so they won't be slowing each other down.

Что делать с поврежденными PST-файлами?

Вам будет предоставлен список всех PST-файлов с ошибками. Чтобы попытаться их восстановить, необходимо запустить программу ScanPST.exe. Восстановленные файлы можно отправить или доставить на дисках в рамках нового задания с новым файлом сопоставления PST с пользователями.

Что делать с поврежденными элементами?

Вам будет предоставлен список пропущенных элементов в доступном для скачивания формате.

While this option works, it creates a significant amount of administrative overhead. You have to manage the process:

  1. The messaging to the users about how and where to move the data.
  2. The issues around database and log management if they are uploading On-Premises
  3. The timelines for each of the settings for locking the PST.
  4. Following up with the users.
  5. Following up with the users.
  6. Following up with the users.

In short, yes, this can work, but will drag out the process significantly.

Option 3: Have Microsoft put your PSTs in your Office 365 Mailbox or Archive Mailboxes for you.

Yes, you heard that right, Microsoft will put them in the cloud for you. This is a great option if you have a large amount of data to upload. You can directly upload the PST files via Azure AZCopy Tool OR ship the disks to us. Typically, we recommend the disk shipping service for data over 10TB.
