Description dag 2022-05-18 06:54:27 UTC

SUMMARY
There seems to be a quite low on the number of messages that can be marked as read at one go.

STEPS TO REPRODUCE
1. Select a folder with many unread messages
2. Mark a largeish number (In my case 6000+) of them and select "Mark message as read"
3. 

OBSERVED RESULT
No marks will be changed. No errors reported. The number of unread messages in the folder will not be decreased,
The same happens when selecting "Mark all messages as read" from the folder menu.

EXPECTED RESULT
The selected messages should be marked as read.

Did some additional testing and the limit for the messages that can be handled in one operation seems to be very close to 1000

I can confirm it.
I will investigate how to fix it.
