In a daily work I have needs to convert Ofice365 mailbox between user mailbox and shared mailbox. It could be needed after employee left or if we would need mailbox with ability to mail sending.
The first difference between these types is that shared mailbox do not require license for office365. In addition, shared mailbox has limited size – 50 GB and there has no login and password, so there is no possibility to configure it as a sender. We can send mails only by delegating permissions to another user. We can delegate it to maximum 25 users.
You can convert it by login to the EAC
First lets convert User Mailbox to Shared Mailbox. After login to EAC go Mailboxes, then choose mailbox to be converted.
Now lets do it the same but in the other side.
If you wish, of course it could be done also by PowerShell. In our case we have now shared mailbox and want to make it as regular. Last command is reverting this change.
