Yahoo transfer email limits

According to the FAQ it says, "Email messages with attachments of more than 25 MB or in an unformatted format will not be moved. They will be moved to a separate folder in your Xfinity Email inbox, and you will be notified that you have 30 days to download them. Only up to 4,100 folders can be moved. Folders over 4,100 will be consolidated into a single folder."

Where it says, "Email messages with attachments of more than 25 MB", Is that for just one (1) email or for all emails.

What about Folder sizes? 

Is there a limit to those? Note: I one Folder that is about 14MB with about 20 emails.

2 other large Folders total about another 13MB total and a few smaller ones that total about 1MB.

Thanks

Email limit size is 25MB, outgoing and incoming, with attachments, so I'm not sure what that means.

I also don't know what the folder size limit would be.  Good question!

@jl747 From my research it is per email. Email messages larger than 25MB need to be downloaded and deleted before your account is moved. All email attachments will be migrated to Yahoo Mail with a few exceptions:

  • Email messages larger than 25MB must be downloaded and deleted before your account is moved.
  • Email messages larger than 25MB that aren't deleted before your move will be put in a special folder, and you'll have 30 days to download and delete these.

I wasn't aware that we could receive an email message [with or without attachments] that is larger that 25MB?  We can't send one, including attachments, that is larger than 25MB.
