--- Comment #3 from Daniel Vrátil <dvra...@kde.org> --- Indeed, sorry about the confusion - I saw in the log it did not use CONDSTORE and automatically switched to Gmail in my head (because I remember the pain of trying to debug that :-)). Office365 doesn't support CONDSTORE at all (it's not listed in the CAPABILITY response), so the only solution to speed up sync is to get rid of the SEARCH and just use FETCH (which should also allow for larger batches and generally will be much faster). -- You are receiving this mail because: You are watching all bug changes.
