Best third party migration tool

[Mike Platvoet]

Hi all,

I am curious after your knowledge and especially your experiences with third party tools to migrate mailboxes (and more?) from O365 to O365. 
Which tool do you like the best, and which one is the worst (if any)?

Let me know!

We don't recommend third-party tools here, as it quickly turns into a spam fest with representatives from the different vendors. There are several tools, look them up, check their product descriptions, etc. There are also multiple reviews/articles out there written by independent consultants, which you can trust more than the marketing fluff you'll get from most vendor's pages. 

If you care mostly about Exchange, I'd recommend sticking with a vendor that has a proven history in that space.

@Rene, bit of a late reply. Does this tool cover shared mailbox migrations too?

@tjhlopezdeleon Yes it does - to the migration tool this is just an account with a mailbox... We usually create the shared mailbox in the target tenant manually and let the tool match it to the source. That way we do not have to assign a license
