I’m changing the mailbox plan on some of the users to change their mailbox quota but it does not change the actual mailbox quota on the mailbox itself. The mailbox plan shows the correct setting but the mailbox size underneath it shows the old quota and also on the exchange the quota is still the old one..
This is generally caused when the Hosting plan OR Mailbox plan does not have :
“Recoverable Items Storage per Organization, MB:”
This value has to be set to 6144 or higher.
If it’s 0 or unlimited Exchange powershell command will error out with an result that the new quota’s never get applied in Exchange it self.
Do note in general you should leave litigation hold off (even with these values filled in).
I’ve checked both settings and they are same as you told. The setting on the hosting plan is unlimited and on the mailbox plan it is 6144 mb.
But the strange thing is I’ve checked the ExchangeMailboxPlans table on the database and the RecoverableItemsSpace is 0 altough it is set to 6144mb. When I manually set it to 6144 everything works fine. I also created a new mailboxplan to double check and I attached the screenshot of this test mailboxplan.
the id of the mailboxplan is 33 on the table
Hey, sorry for my late reply.
It’s been a weird week with liberation day etc in between.
I did some quick tests and i think your mailbox plan doesn’t update due to the hosting plan – unlimited value.
When you change that to 6144 mb or higher it does work as you would expect. (atleast from my tests).
Can you reproduce this?
