    TonyRedmond Have you heard of large organizations placing all mailboxes on litigation hold and enable auto-archiving on all mailboxes as to avoid issue with mailboxes reaching max capacity?  Pros/cons?

escupham Yes to both. There's no real downside. With EXO you don't pay for the extra space required for litigation hold or archives (unlike SPO where retention can consume lots of your storage allocation). One thing to keep an eye on is the size of the Recoverable Items quota. You get 100 GB and this can be increased by Microsoft, but if you have litigation hold enabled for very large or very active mailboxes, that quota can erode quickly.
