SUMMARY I have Kontact running on several computers connected to two different IMAP accounts. One IMAP account is running on Cyrus and the other is connected to Microsoft Office 365. I am seeing both accounts repeatedly syncing the inbox folders almost nonstop. Every time I go to open an email it starts syncing. These accounts hold a lot of email. The Cyrus account has easily over 200K emails in the inbox. I have run akonadictl fsck and akonadictl vacuum as well as restarted akonadi yet the problem continues. Note that I also have Akonadi configured to use PostgreSQL. This behavior is occurring on several computers connected to the same IMAP accounts. Periodically I have to restart akonadi when Kontact cannot open emails. STEPS TO REPRODUCE 1. Start Kontact 2. Open an email 3. Kontact starts syncing the folder for each email opened OBSERVED RESULT Constantly syncing the Inbox EXPECTED RESULT It should not be constantly resyncing the Inbox SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: OpenSUSE 15.0 with latest KDE/QT/Plasma repos (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Dear Aaron, thank you for your report. I saw this as well with Office 365 IMAP. However, I found the default interval is 5 minutes, see settings of IMAP resource. If you have a lot of folders that may explain the regular syncing activity. I set it to 30 minutes meanwhile and it has been better since then.
My interval is set to 60 minutes.
I am still seeing this problem with 5.24.0.
I might add that I am not using Office365 due to the fact that Akonadi does not support OAUTH2 authentication. This is happening with Cyrus IMAP.
