It is a common query of Exchange users

of Exchange users, Microsoft provides the facility to customize the storage

procedures Exchange admin can change the size of mailbox according to the user’s

So today, we will discuss the methods of
increasing Exchange 2010 mailbox size limit. However there are two procedures
to modify the size of mailbox in Exchange server such as by using Shell command,
or by configuring storage quota in EAC (Exchange Admin Center). But before
follow the below procedures, you need to assign the permissions. So first check
the RecipientsPermissions, then follow the below steps.
Increase
mailbox storage quota in Exchange 2010
Firstly, we are using EAC to configure
mailbox quota.
EAC
(Exchange Admin Center) to configure storage quota of user mailbox:
1. Open Exchange
Admin Center (EAC) and navigate to Recipients
> Mailboxes.
2. A list of
all the mailboxes will appear by click on Mailboxes, now you can select here the
targeting mailbox that you want to change the storage quota. Select the user
mailbox and click Edit to change the
property of this mailbox.
3. Just
click Mailbox Usage then click More Options on the property page of
mailbox.
4. Now
configure the following boxes by clicking on Customize the settings for this mailbox. Value can be set here from
the range of 0 to 2047 GB (gigabytes).
o Issue a warning at (GB)
This box shows the maximum storage
limit of mailbox before delivered a warning message to the user. Exchange sends
warning message to Exchange user once their mailbox reaches or become exceed
more than value identified.
o Prohibit send at (GB)
This box shows the forbid limit of the
Exchange mailbox. Exchange sends and shows a new detailed error message to user
if the limit of the mailbox has outdone to the set limit.
o Prohibit send and receive at (GB)
This box shows the forbid send/receive
limit of the mailbox. Exchange stops the mailbox from delivering or sending any
new message once mailbox size limit cross the specified limit. All messages
which sent to that user’s mailbox return to the sender with detailed error
note.
5. Now just
click Save and that’s it.
You can increase the size limit of
Exchange 2010 mailbox by using EAC.
Now verify that the above
configuration has been working or not.
o Go to EAC,
navigate to Recipients > Mailboxes
o Select the
mailbox from the list to verify the storage quota, and click Edit.
o Click Mailbox Usage then click More Options on the property page.
o Now verify
that Customize the settings for this
mailbox has been selected. Just verify storage quota setting that you made.
However there is another method to
customize the mailbox storage quota. Just use Shell commands to configure that.
Use
Shell command to customize mailbox storage quota:
By running few lines of shell scripts
you can easily customize the mailbox size in Exchange Server 2010.
Set-Mailbox
-Identity "Davidson" -IssueWarningQuota 30.5gb -ProhibitSendQuota
35.75gb -ProhibitSendReceiveQuota 40gb -UseDatabaseQuotaDefaults $false
By running the above Shell command,
you can set the issue warning, forbid send, and forbid send & receive
quotas for Davidson's mailbox to 30.5 GB, 35.75 GB, and 40 GB individually.
Set-Mailbox
-Identity "Charles" -IssueWarningQuota 800mb -ProhibitSendQuota 850mb
-ProhibitSendReceiveQuota 1gb -UseDatabaseQuotaDefaults $false
By running the above Shell command,
you can set the issue warning, forbid send, and forbid send & receive for
Charles mailbox to 800 MB, 850 MB, and 1 GB separately, and configures the
mailbox to use custom settings.
That’s it. Now run the below scripts in
Shell to verify that required storage quota has been configured. Run the below
command to check that.
Get-Mailbox<identity>fl
IssueWarningQuota,ProhibitSendQuota,ProhibitSendReceiveQuota,UseDatabaseQuotaDefaults
