Our organization is going to Office 365 from Google Apps, and we were trying to figure out the best way to approach legal holds. First of all, I have heard two rumors that I couldn't find a specific answer for.
First, Is litigation hold being deprecated? I have seen claims from other users online saying that they receive this prompt, but we never received such a prompt and it seems to work fine.
Second, we also heard through a random vendor that license agreements only allow 15% of users in an organization to be on Litigation holds. I could not find an account of this anywhere online, either...wasn't sure if this is true.
If the two above criteria are true, what we want to do is have ALL users on our domain to have their email held for 1 year, regardless of if they delete it. Is the Litigation hold the proper option for this, or should we use In-Place hold or Journaling? Litigation hold seems to work well for us so far (we are in trials with about 20 users), but I wasn't sure if the above claims were valid.
