When excluding users that mailbox was converted to shared mailbox, implies in exclusion of shared mailbox. This is correct behavior?
I have some users in Office365 that were fired of the company. Those users I converted the mailbox to shared, after I exclude them in Office365 Admin Portal. When users were excluded, shared mailboxes are excluded too. This is normal behavior or I forgot any step during conversion? There are another solution?
The best way to deal with users leaving the company is to use Inactive mailboxes: http://technet.microsoft.com/en-us/library/dn144876(v=exchg.150).aspx
You will need Exchange Online Plan 2 licenses to put the mailboxes on hold however.
