Hi. I've been using WLM12 since Outlook Express was dropped, and it's been a great mail app for me. For about the last month or so, WLM12 performance has been very poor on both my wife's computer and on mine. What used to be a 10 minute job to go through the day's mail and delete or store messages, has become a 30 or 45 minute job, which often ends without completion. Both mine and my wife's computers are Win 10 machines with the anniversary update. The nature of the problems is very much the same on both machines. I initially assumed the problems were due to some MS update and that the problems would be discovered and fixed. Well, that hasn't happened so I thought I'd try here.

All the problems seem to be associated with the IMAP server and our Hotmail accounts. We have No problem with any of our gmail IMAP accounts which we also read with WLM12. We get many error messages during EVERY attempt to read and process our Hotmail. I have included a few examples of  messages we receive every time we try to read our Hotmail.

Would appreciate any suggestions for how I can improve the performance of WLM12. Thanks.
