After the email migration, some customers may see two Sent folders in Outlook. This happens because the old and new email platforms use different names for the Sent Items folder. Your sent emails have not been deleted. They are still in your mailbox and can be found by checking both the Sent and Sent Items folders.

Outlook mailbox size limit

If your Mweb mailbox is larger than 50GB, Outlook may not sync all your mail because of a built-in file size limit. You can safely increase this limit in Windows to keep using Outlook without losing mail.

How To Use Outlook With a Mailbox Larger Than 50GB

mailbox quota warning

If you’ve received a mailbox quota warning from Mweb, it means your mailbox is almost full. Learn how to free up space safely or upgrade your mailbox storage.

Mailbox Quota Warning – What It Means and What to Do

SMTP server

If you’re unable to send emails while connected through Mweb, it’s likely because your email address is hosted by another provider (like Telkom). According to international RFC email standards, you must use your email provider’s SMTP server to send mail, not the one from your connection ISP. Update your outgoing mail settings to match your email provider to fix the issue.

Why You Can’t Send Mail When Connected Through Another ISP

If you’ve checked your IP address and noticed it’s listed on a PBL, don’t worry. This is normal for most home internet connections and doesn’t mean there’s a problem with your Mweb email service.

Why You Might See a PBL Listing When Checking Your IP

If your email fails to send due to a blacklisted IP, it could be caused by CGNAT on the network you’re using to connect, not by Mweb’s mail servers.

What Is CGNAT?

If your email domain isn’t hosted with Mweb, use your own provider’s SMTP details instead of smtp.mweb.co.za. This ensures your messages are sent correctly and keeps Mweb’s network secure for all users.
