This warning message is played either when users log in to their
mailbox after their password is entered or when an outside caller tries to
leave a message for a subscriber, and the mailbox of the subscriber is full:
“Your inbox is almost full – if your mailbox exceeds your storage limit, you
will not be able to send or receive new messages.”
The mail-limit-message prompt can be disabled on either a per-mailstore
or per-user basis.
Basically, all the messages are stored on the Exchange mailbox; by
default, the Cisco Unity server watches the mailbox limit for the user.
If you want to disable the limit prompt on a per-mailstore basis,
follow these steps:
Open the Exchange System Manager and expand the
tree until you see the mailbox store, for example, Servers >
YourServer > First Storage Group > Mailbox Store.
Right-click the mailbox store and choose
Properties. Click the Limits tab. Under
Issue warning at KB, either disable the option, or set an
unrealistically high value, click apply, and click
Repeat this step on each mailstore that you want to disable if you
have more than one mailstore. This only affects users that go by the mailstore
defaults, but it does not affect anyone that has custom settings. In order to
take care of those users that have custom settings, use the next solution.
Note: You can complete the previous steps also from Cisco Unity
Tools Depot > Administration Tools > Message Store Manager > Scripts
> Set mailbox limit > Issue warning at KB.
If you want to disable the limit prompt on a per-user basis, follow
Go to Active Directory Users and Computers. Then
go to View > Advanced Features.
Search for the user; right-click the user, and choose
Choose the Exchange General tab, and click
Uncheck the Issue warning at KB option to disable
it, or set an unrealistically high value, click apply, and
You can receive the Your mailbox is full
error message when Cisco Unity and Exchange are out of sync. In order to
synchronize Cisco Unity and Exchange, from the Command Prompt, type and run
<drive where Cisco Unity is installed>:\commserver\configurationsetup\setup.exe /sync
For example, C:\commserver\configurationsetup\setup.exe
/sync if Cisco Unity in installed in the C: drive.
Note: This synchronizes all Cisco Unity objects with the directory. This
can take some time and can cause a performance hit on the Cisco Unity server.
