Unfortunately as great as Microsoft Outlook is (most popular business email client, extremely customizable, seamless integration etc), it does have its “moments”!
One such time is when emails dont seem to want to send! They stay in the Outbox seemingly staying there forever, just trying to resend over and over
To make matters worse, the email recipient often receives your email multiple times, and deleting your email from your outbox can be a nightmare!
More often than not, the perpetual email sending and stuck email is caused when a user tries to send more than a 20MB attachment through their privately hosted mail server. This can be either:
Generally speaking (and to avoid problems!), 20MB is the absolute limit with privately hosted mail servers. (Hosting providers often set their limit at 25MB to avoid these problems, but if your reading this, it’s a safe bet to guess that your provider doesn’t!) In such cases, 20MB doesn’t mean 21MB, it doesnt mean 20.5MB. As mentioned above, 20MB is the absolute limit. Think of it as a truck going into a tunnel at speed along a highway, with the tunnels clearance height being 20 meters. If the height of the truck is 20.5 meters… there is going to be a BIG problem!
Option 1: Zip your attachments. You can even break the Zip into smaller files (eg 2 x 10.2MB) and send each separately
Option 2: Use a cloud solution. Uploading large files to a cloud solution is far more forgiving, and if you use a solution such as DropBox for example, you can just send your recipient a link to the file and they can then download it at their leisure
Option 2 would definitely be our recommendation
What would also help:
Increasing your internet upload speed to avoid server timeouts. This sounds trivial, but if you have a particularly poor internet plan and multiple PC’s Laptops etc all doing updates and/ or streaming – sending a large email attachment is going to be a challenge!
