Hello all. I am new to Linux. Settled on Plasma and using Kubuntu 20.04, Kmail 5.13.3

I have set up 2 microsoft outlook and one gmail account in Kmail. All appears to be working well.

However when i select all messages in some small gmail inbox sub-folders (i.e. fewer than 50 messages in total), then move to main Gmail inbox, i find that

(i) sometimes all the messages are moved out, as expected
(ii) sometimes only some messages are moved out - the others then seem 'stuck' and require several attempts to move them successfully.

I am possibly a bit too noobie to be submitting bug reports and didn't want to unless i was sure this is a bug.

Can anybody else replicate this behaviour?

Many thanks
Aniche

I just setup as you indicated. Gmail account. All seems to be syncing fine and moving fine.
