Yahoo!/AOL IMAP collection emails per folder limits

Josh Smith

UPDATE: November 16th, 2022: 

We have unfortunately now received reports that the export.imap.mail.yahoo.com and export.imap.aol.com servers have a folder limit of 100,000 items per folder. The folder’s item count will report the total number of emails in the folder but the Yahoo! and AOL servers will only provide Aid4Mail with 100k items.

If you experience something different, please get in touch with us.

UPDATE: July 1st, 2022 

Aid4Mail version 5.0.16 now defaults to the export.imap.mail.yahoo.com and export.impa.aol.com serves. You can upgrade your version of Aid4Mail 5 by clicking here.

-If you have Yahoo! or AOL accounts that were already added to Aid4Mail 5 before this update, please simply update the Server name/IP address.

UPDATE: June 30th, 2022

We have found new information that using a different Yahoo and AOL IMAP server will allow you to process 100k emails in each folder. See articles and details below:

Yahoo! Server details

Server name/IP address: export.imap.mail.yahoo.com (instead of imap.mail.yahoo.com)

Port:  993

AOL Server details

Server name/IP address:  export.imap.aol.com  (instead of imap.aol.com)

Port – 993

It has come to our knowledge that Yahoo!/AOL has now imposed new limits on how many emails can be collected per folder when collecting via the IMAP protocol. The limit is 10,000 emails per folder.

If you use a search query or try to collect all the emails from an account, you will only be provided 10,000 emails per folder.

We are currently looking into what can be done in Aid4Mail to work around these limits.
