Outlook IMAP problem; imap folder sync error

Recommended Posts

As of last week I experienced a problem in Outlook 2010 using IMAP.  (Windows 10, Outlook 2010, Eset Antivirus V10)

The IMAP folder sync process could not finish in good order.

It looked like Outlook freezes/hangs after starting. So I installed outlook 2016 after having updated Windows 10, but no improvement.

I discovered that everything worked well after disabling all ESET antivirus functions. Thus being it a problem caused by the Eset Antivirus.

I tried some things and:

The fact is that after I disable "IMAPS control"  my Outlook works fine.

SO in:  Internet SecurityEmailclient security/protection, click the Advanced settings pictogram.

In the advanced settings, Emailclientsecurity, scroll down to Email protocols and expand using the + sign

Disable the IMAPS-control and save it by clicking OK


Question to Eset: Is this going to be fixed?

Also try switching to pre-release update and test it with the very latest modules.

Should the problem persist, enable advanced protocol filtering logging in the advanced setup -> tools -> diagnostics and reproduce the issue. Then disable logging, collect logs with ELC, upload the generated archive to a safe location (e.g. Dropbox, OneDrive, etc.) and drop me a message with a download link.

Do you know what software is used as the email server?
