Your IMAP server wants to alert you to the following: Email is too large, limit size to less than 20MB

The famous IMAP issue that I can calls on occasion about, I bet you are here looking on how to fix this. In short, you need to go through each folder including the inbox…

Sort by size.

• Find all emails with sizes larger than 10MB. Move them to a local PST file.
• Then go find any 0KB size files, these are usually corrupted but have a large amount of data in them. (This is super important!)
• You can use the “Search folders” option in your Outlook folders list and find files larger than 100kb too.

Then close Outlook and see if it happens again. Should be gone!
