IMAP responds very slowly (ME 10.23)

Post by malikguy » Wed May 08, 2019 3:04 pm

Hello, we are seeing issues with IMAP on mobile devices and Outlook where unread messages or deleted messages do not retain their state. For example, if you read an email, it may come back as unread or if you delete and email, it may show back up. It seems this occurs when there are multiple commands issued in a close time period through the IMAP protocol. This does not seem to be the case in Web Mail as updates "stick" when issued through the Web Mail client.

This has been an issue for as along as I can remember on fairly large mailboxes (500 MB+) even in ME versions prior to 10.23.
