By Jennifer MahoneyToday we’re going to take a look at the top three e-mail issues that users encounter, why they occur, and how to avoid them.‘User Unknown’ is an error message that we are all familiar with. Here are a few reasons that cause this error message to occur:-The email account of the person you are trying to contact no longer exists or has been temporarily suspended.-The name of the recipient has been spelled incorrectly.-The domain is spelled incorrectly or is wrong. I often find myself automatically reverting to our local domain .bm when sending e-mails, which causes bounce backs if they are on a .com, .org or any other domain.If you have double checked all of the details used and they appear to be correct, contact the intended recipient and let them know you are receiving bounce backs as there may be an issue with the email provider.Another common error message received is ‘mailbox is full’, which indicates the intended recipient has reached their maximum allotment of storage space on the email provider’s server. This needs to be rectified by the recipient and they either need to remove some of the messages stored, or if available, request an increase in storage limits.Often we send e-mails only to be told by the recipient they did not receive them, because we did not receive an error message we automatically assume they were received. Generally these are trapped in the junk e-mail or spam-catching tool being used by the intended recipient.Have the recipient check to ensure they have not been captured and request they add you to their contacts, to help prevent this issue going forward.If you have had ongoing issues sending e-mails to a particular address and the file you are sending is important, I suggest you use the delivery receipt function contained in your e-mail client. When using the delivery receipt function you will automatically receive notification when successful delivery has occurred.Sending large attachments has always been a point of frustration and initially we battled this issue by compressing or zipping our files before sending them. The allotted attachment size of files we are allowed to send varies based on our ISP or the mail client (Gmail, Hotmail, etc) we elect to use. Average attachment file size is around 10MB, but I suggest you take a minute to find out what your limits are.In addition to compressing files, there are many free online file sharing/storage sites available and next week we’ll take a look at the pros and cons of a few.We’d love to know what topics you’d be interested in learning more about, so e-mail us at techbuzz@btc.bm.
