I'm converting a client to Office 365. We are using Office 365 Business Essentials plan.
One of the owners has a very large amount of data in regards to folder contents and size.
There is about 17GB on his current Imap server.
The inbox has been broken down into semi-annual archive folders (just a label, not the actual Outlook archive folder.pst).
i.e., 2010a Archive, 2010b Archive. This is to accommodate the 25,000 item per folder on his current mail server.
Each Archive is around 2GB.
I'm planning on putting all this mail up to office 365 so that he can continue to see it from his various devices (W7pc at office, 2 ipads, iPhone, iMac at home, OWA.
My question is "Does it matter how I put the various folders on the server?"
For example would it hurt to put all the folders under Inbox? Should I make a separate "archive" folder at the root level of his mailbox, then add the archives under there?
I just don't want to run into an issue where he hits some sort of limit that will affect his mailbox in the form of receiving, recovering deleted items, or anything else I may be overlooking.
