SUMMARY Akonadi repeatedly spits this out whenever I receive an email with over 300 names in the CC list with an IMAP account on Office365.com. STEPS TO REPRODUCE 1. Have corporate send out a mass invitation calendar event with 306 entries in the CC list. OBSERVED RESULT When Akonadi hits this it keeps spitting out the above. Here is the debug output: C: A000005 CAPABILITY S: * CAPABILITY IMAP4 IMAP4rev1 AUTH=PLAIN AUTH=XOAUTH2 SASL-IR UIDPLUS MOVE ID UNSELECT CLIENTACCESSRULES CLIENTNETWORKPRESENCELOCATION BACKENDAUTHENTICATE CHILDREN IDLE NAMESPACE LITERAL+ S: A000005 OK CAPABILITY completed.

HUGE CC list, last column is 15411 and the CC list is terminated with a ^M ... S: Cc: BAD Command Error. 10 X EXPECTED RESULT It shouldn't barf. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: Akonadi version: 21.07.80 ADDITIONAL INFORMATION Deleting the email and calendar entry from the Outlook web interface does not fix this and it continues to barf on this, even after I have completely deleted it from the deleted items recovery folder. akonadictl vacuum and fsck do not fix this either. It is forever stuck on this email. Once it hits this email, it is unable to donwnload any newer messages.
I was finally able to clear the email using the akonadiconsole. Somehow the email was stuck in Deleted Items. Note that this problem happens every single time I get an invitation to a large corporate event with a bazillion CC entries.
This is really becoming a problem as this is happening every time I receive a corporate-wide email.
This time the Akonadi console was unable to clear it out. I deleted the file_db_data and search_db_data and ran fsck and this cleared up the problem. This problem happens every time I receive a corporate-wide email. My guess is that something in Akonadi cannot handle such a long cc list.
This is happening every time there is a corporate-wide meeting where there is a huge CC list.
