I'm interested in using some of the MessageOps tools that they provide for free once they are set as the partner on record so I'll likely be going forward with them. Before I do that I was looking for feedback on who you are all using. I'm currently in the migration stage (using MigrationWiz) so I'm calling MS more frequently than I expect to down the line. MS support has been pretty good so far but it's frustrating when they pair me with a tech who works a very different schedule than me (why do they do that!?!?).
I purchased my licenses via CDW and they certainly said they can help but then it became a bit murky as it seemed like they wanted to charge for professional services at times.
