            Bug ID: 397140
           Summary: akonadi gets stuck downloading new emails
           Product: Akonadi
           Version: unspecified
          Platform: openSUSE RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: IMAP resource
          Assignee: kdepim-bugs at kde.org
          Reporter: aaronw at doofus.org
  Target Milestone: ---

I consistently have problems where akonadi gets stuck downloading emails for my
work email account.  I see this problem with multiple computers.  I have to
manually run 'akonadictl restart' in order for it to begin picking up new email
messages again.

I have run akonadictl fsck and akonadictl vacuum on multiple occasions and that
does not help.  This has been going on for at least a couple of years and I'm
currently running 17.12.3 as is shipped with OpenSUSE 15.0.

My email account is hosted by Microsoft's office365 service. I have a lot of
emails, with over 58,800 emails in my inbox, most marked read.

I rarely, if ever, see this problem with my home imap server where I have
several hundred thousand emails stored which uses Cyrus imap.

I can reproduce this problem with three different computers.

For office365 the connection uses STARTTLS with plain authentication. The
server  info is:
IMAP4
IMAP4REV1
AUTH=PLAIN
AUTH=XOAUTH2
SASL-IR
UIDPLUS
MOVE
ID
UNSELECT
CLIENTACCESSRULES
CLIENTNETWORKPRESENCELOCATION
BACKENDAUTHENTICATE
CHILDREN
IDLE
NAMESPACE
LITERAL+
