Hi, Exchange Online detects ~2500 mailboxes in the Exchange Office 365 app. The customer shows me a screenshot indicating he has only 1250 Microsoft 365 E3 licenses assigned. What causes this mismatch, is there a problem, are more Commvault user licenses necessary? Thanks.
Let me look into this for you before we create a case. I believe I have the answer here:
- In Exchange Online, you have 2392 mailboxes, of which 1250 are licensed in Azure/MSFT 365/Exchange Online
- The backup ‘sees’ all 2392, and ‘intends’ to back them up
- however, for each unlicensed mailbox, we will give this error:
- Invalid mailbox license. So skipping mailbox
- The backup will complete and only protect 1250, which is what you will see in your CV license usage
I am 99% sure that is what will happen, though I want to confirm with our docs team.
From what we state here:
Usage Decrease
License usage can decrease because of any of the following actions:
-
Exchange Mailbox Agent:
-
Removing existing mailboxes from subclient content.
-
Disabling backup activity on a subclient with mailboxes as content.
-
I want to ensure that we don’t ‘count’ skipped at all, as well as how we handle protected mailboxes that are unlicensed after the fact.
I’ll let you know what the docs team confirms (and have the docs updated)!
FYI,
Hi Mike, I am not in charge of this ticket, but in that case I guess we can close this one. Thanks so far!
Thanks!
Hi Mike,
I see:
- 2392 Mailboxes mentioned in Command Center (Exchange Office 365 app)
- 2392 Total Mailboxes mentioned in the first Exchange Online backup job I started
- 1250 Microsoft 365 E3 Assigned licenses in a screenshot of the customer
- 0 of Total 1250 Mailboxes used in Licensing and Registration
I have suspended the first backup, reason why I not see any used mailboxes yet in Licensing and Registration.
I just don't want to resume the job, which has already backed up a number of mailboxes by the way, before this is cleared.
Maybe I should open a ticket for this.
Thanks.
Hi, I just counted and Commvault “sees” in Command Center 1328 user mailboxes. The rest are shared and group mailboxes (which are also backed up). Of these 1328 mailboxes, Commvault indicated 8 were “not processed” (leaves 1320 backed up). How this fits in with 1347 Commvault licenses in use and only 1250 Exchange Online mailbox E3 licenses, I don't know. As long as the total percentage of over usage is less than 110%, fortunately there doesn't seem to be a problem.
Might be shared mailboxes.
I heard back from our dev team:
MSFT consumes a license for user mailboxes but for shared mailboxes they don’t. Similarly we consume license only for user mailboxes which are licensed by Microsoft.
All other types of mailboxes will not be included.
I asked for the docs to get updated to clarify.
Hi
Yeah, that’s an unfortunate place to find yourself. Do you know which mailboxes are the ‘extras’?
I’m working with our docs team to get this all updated to avoid these issues going forward; I’m just now really curious as to where those extras came from.
Hi, Today I happened to see that a colleague of me has opened a Ticket (Incident 211019-182) for a similar issue at a different customer. It shows among others 2 screenshots: 1 of a mailbox not being processed in Command Center, and one of that same mailbox consuming a Commvault license. I will wait if that ticket will be resolved. Hope this helps!
It does! I’ll track the case as well.
Let me know how it looks when completed and Licensing is applied.
I’m still working with a few groups to narrow down our expectations.
