Trying to choose a pst migration tool...help!

Doing a pst migration in tandem with an email migration into O365. We are using native tools so far, but with the nature of pst imports into O365, the manual process of setting up batches has been a bear to deal with. All the users are storing psts on their personal network share, so not a centralized location. Many users have multiple psts of varying sizes.  They are willing to consider a 3rd party tool to help, but there are so many out there. I haven't used any yet. Can anyone suggest what tools they have used, what they liked and disliked? Trying to make an informed decision without all the sales hype. Thanks!

Well, there are many factors to consider, but you can start by telling us how many users, and how big is the total size in GB? Quadrotech's PST FlightDeck is probably the most robust tool out there, but if this is a small project, the price might be prohibitive.

Their personal network share should be on a file server so centralized? Or, is that share from their local PC?

The simple thing to do would be to have the users copy that .PST file to one location and run the script from there.

Another option would be to run a PowerShell script to harvest the PC names and the user names from AD and put together a PowerShell script that runs against those two to pull the .PST file in.

about 8,000 users, some having up to about 10 psts, but most having about 2-3. They range in size from just a GB or 2 to 100 GB.

Yes a centralize file server, a home drive mapping. The company is trying to make this as seamless as possible to the user and I doubt that reaching out and having the users copy their psts to a single location won't work, also there are privacy concerns.

The files are at rest on the file server then. Why not upload them from there? Again, a PowerShell script could be used for this.

Where's the Partner of Record? They should have a proven methodology for this situation.

So you are definitely in the TB range then, right? I would strongly recommend using a specialized tool or even performing a "managed" migration with the help of the vendor.

Hi,

As you have a large number of PST files which you want to migrate to Office 365, then I will suggest you use SysTools Office 365 Import Software.
Using this tool, you can easily transfer all your PST files irrespective of their file size and the count of the files.

You can also refer to this link to check that one user used this tool import PST files to Office 365 and got satisfactory results.

Some really great options here guys, thank you! I did research the managed service option and my company is opposed to that solution. However I have saved the link for my next project. The software Clark Kent (awesome name btw) seems to be everything we need, thanks again!
