Did you try to log in with Jamk’s user ID? Sometimes prior IDs are stored in the computer cache, and therefore it makes sense to try another browser, or to clear the browser cache and try again thereafter. Outlook also sometimes stores previous IDs. Try to first log out of your previous Outlook account (and clear the cache) before logging in with a Jamk user ID.
If you tried to log in several times in a row, the system will notice the failed attempts and lock the user account for a specific amount of time. A block that has been put in place after several failed logins in a short amount of time will be lifted automatically after a while. If you know what the problem is, fix it, and wait for a few hours.
It is also possible that your user ID has been locked because your study entitlement has expired. If you are uncertain about this or the situation does not correct itself automatically, please contact us.
