In browser, changes do not update without reloading.
I work for an organization which uses shared calendars across the entire company. In the Outlook application, appointments that are re-categorized or edited are updated almost instantaneously. In the browser, however, changes by others do not update until the page is reloaded or occasionally if the appointment is manually opened.

Since recently I noticed new e-mails are not coming up in the mailbox unless I reload whole website. It might cause some e-mails to be missed. It hasn't been happening before
