Why Upload PST Files to Exchange Server?

Many businesses utilize PST files to maintain their calendars, contacts, and emails. These files are from ancient Outlook accounts or backups that were made in the past. It is safer, easier to get to, and easier to handle when you upload them to Exchange Server. You can access everything from anywhere with Outlook or webmail.

But if you have a lot of PST files to upload, like dozens or even hundreds, uploading it one at a time is not a good idea. That's where automation comes in.

Manual Method to Upload PST to Exchange Mailboxes

You can attempt Microsoft's manual method before utilizing any third-party solution. This means using Microsoft 365 Compliance Center's Network Upload. But it's not easy for beginners to use, and it's only accessible for Microsoft 365 Exchange Online (not on-premises).

Here's a summary:

Step 1: Get PST Files Ready

• Put all the PST files in a folder that everyone can see.
• Make sure that file names are clear and easy to connect to usernames.

Step 2: Get the AzCopy Tool from Microsoft

• Use it to put PST files in the Azure storage space that the Compliance Center gives you.

Example command:

AzCopy.exe /Source:C:\PSTs /Dest:<AzureURL> /V:<logfile> /Y

Step 3: Make a file that maps things

• Link PST files to mailbox addresses using a CSV format

Example:

Mailbox, FilePath, TargetFolder
johndoe@example.com, johndoe.pst, Inbox

Step 4: Bring in PST Files

• Return to the Compliance Center
• Use your mapping CSV to do a new import task.
• Begin the import process

Problems with the Manual Process

• It only works with Exchange Online, not with Exchange Server on-premises.
• Needs technical setup and admin roles
• Needs to set up a CSV file and use the AzCopy command line
• You can't see or choose which folders to import.
• There is no straightforward mechanism to handle large files for several users.

This method isn't great if you're not experienced with command-line tools or CSV mapping. It also isn't made for quick or regular migrations.
