Environment: Exchange 2010, Outlook 2010
Assume user has 20,000 emails in Inbox.
I know Microsoft states folder limit of about 100,000 emails, but also states best to keep Inbox, Sent items, etc. to less than 5,000.
Would it be better to:
1. Account/New Folder/Subfolders (to move items from Inbox, by year or whatever) or
2. Account/New folder (one new folder for each year or whatever).
If user goes with option 1 does this create the same problem as storing all email in Inbox?
