Select All functionality needs changes
There are 2 issues in O365 emails.
1. When we put any keyword in search filter, we do not get all emails related to that filter criteria. We get only few. And then again we have to apply search in order to get a list of remaining matching mails.
2. When we have a list of emails as per our search criteria performed, we click on checkbox of Select All, but this checkbox only selects 5 emails at a go i.e emails in view and then we have to click on delete and again have to click on select all checkbox to select next 5 to be deleted. I mean it is irritating that we are not able to select all emails displayed in Search criteria in order to delete all at one go.
