If Outlook is running slowly, you can turn on something called 'cached exchange mode' to speed it up. Regularly cleaning out your inbox will also improve performance.

Cached exchange mode

Cached exchange mode saves a copy of your mailbox on your computer. So, instead of waiting for UQ's mail servers to send data to your machine, you can access data locally from your device.

This speeds up performance because it bypasses the mail server (and several other systems), which can be slow to send and receive data.

The mailbox copied to your computer will still be frequently synced with the mail server, so all your emails will be backed up and kept safe.

Turn on cached exchange mode

These instructions are for Windows 10:

  1. Open Outlook.
  2. Go to the blue 'File' tab and select 'Account Settings' then 'Account Settings'.
  3. Select your email address, then click the 'Change' button.
  4. Under 'Offline Settings', tick the 'Use Cached Exchange Mode' box.
  5. Set the 'Mail to keep offline' slider to 6 months. This will keep the mailbox size manageable on your computer. Click 'Next'.
  6. An alert will advise you to quit and restart Outlook. Click 'OK', then 'Finish'.
  7. Close and restart Outlook.

You should save 6 months of your personal mailbox and turn off cached exchange mode for any shared email accounts. This will keep the mailbox on your computer manageable in size. You can copy up to 12 months of emails to your computer.

Clean out your inbox

If you're hanging on to emails from years gone by, you can export and save them. Once your old emails have been exported, you can delete them out of your inbox.

Deleting old mail will keep your inbox light and trim, and make it easier for the mail server to manage. You'll still have a record of your old emails in the exported file.
