There are a few common reasons why Outlook  may be having issues. These can include no internet connection, too many emails, and large attachments.


  1. If your email is not sending/receiving emails, check the bottom right corner. If it says Not Connected to Edu, follow these steps.

  2. Ensure that you are connected to the PLCScotch WiFi, by clicking on the WiFi icon in the top right corner of your screen. There will be a tick next to the WiFi you are connected to.

  3. Once you have connected to the PLCScotch WiFi, it should say Connected to Edu, or Connected to "Your Name", shown below.

  4. If the problem persists, please see this FAQ to check whether your account is correctly set up: How do I set up my email in Outlook?

Too Many Emails/Folders

Outlook may also not work if you have Too Many Emails stored in your inbox.

There is no definitive number of emails that is too many, as it mainly depends on how big those emails are, e.g. what attachments they have. For example, I may have 1000 emails in my inbox and have no problems; however, someone else may have 500 emails, and Outlook will run slow, and have difficulty sending and receiving emails. 

Another issue is Too Many Folders. It is recommended not to have more than 500 folders, as this can cause folders to display incorrectly, or they can take a long time to appear, especially in cached mode. In extreme cases, when there are more than 1000 folders, Outlook is very slow to open. This behavior occurs because it takes a long time to enumerate the folders.

These problems are easily solved - all it requires is to:

  • Notice any problems early on, e.g. Outlook is running slower than usual.
  • Keep aware of how many emails/folders you have, and what is in those emails, e.g. large attachments.
  • Delete Things When You No Longer Need Them.
    1. To delete emails off your computer, but not your account, you can go Offline, and delete emails normally. This way you will stay have access to those emails via Webmail, but you can free space off your computer.

      Firstly go Offline, by clicking Outlook in the menu bar in the top left corner, and selecting Work Offline.

    2. Check you are Offline by looking at the bottom right corner, it should say Working Offline.

    3. Then simply delete emails as usual.

Large Attachments

If you have tried to send an attachment larger than 20 MB, you will almost certainly experience errors in Outlook, as the email will repeatedly try and fail to send itself. To solve this issue, follow these steps:

  1. As above, from the Outlook menu, select Work Offline.

  2. You should notice, near the bottom left of the Outlook window, your Outbox will appear. This is where your emails go after you click Send, but before they arrive at their destination. Usually an email would only be here for a matter of seconds, but if you have tried to send a large attachment this is where it will get stuck.

  3. Select the offending email and click Delete.
