When activating a KMS server you receive an error that says, “Error: 0x80072EFD”
This will happen when the server does not have Internet access. Temporarily allow the server to have Internet access then try again. You should get a message that says, “Product activated successfully.”
When a user tries to save an appointment on a shared calendar in Outlook she receives an error that said, “The message store has reached its maximum size. To reduce the amount of data in this message store, select some items that you no longer need, permanently (shift + del) delete them.”
This can happen if a Storage Quotas value has been set for Prohibit send and receive in Exchange.
To resolve the issue you can either remove items from mailbox that are no longer needed or increase the storage limit. However if you increase the storage limit it can take up to 2 hours for the setting to take effect. See this link for more details. A quick workaround (quick being relative to the size of the mailbox in question) is to move the mailbox to another database. Once the mailbox has been moved the updated storage quota setting will take effect.
In Windows 8 when using the Windows 7 File Recovery tool to restore files to an alternate drive you may receive an error that says, “A file cannot be restored. Error: Short names are not enabled on this volume (0x80070131).”
In Windows 8 all drives other than C have 8.3 name creation disabled. You can verify this by running the following commands from an elevated command prompt:
fsutil behavior query disable8dot3 c:
fsutil behavior query disable8dot3 e:
Notice that 8dot3 is enabled on the C drive but disabled on the E drive. To enable 8dot3 on the E drive running the following command from an elevated command prompt:
fsutil 8dot3name set e: 0
Now attempt the restore again & you should not receive the error.
