Recently had a user not be able to delete items from another Users exchange Mailbox ( 2010 )  apart from having full permissions to the Mailbox 

Exchange 2010 Mailbox has a 30GB limit of the Recoverable Items Folder

To find this current quota run : 

Get-MailboxFolderStatistics -Identity %username% -FolderScope RecoverableItems | Format-List

To delete them , run :

If you can’t find Search-Mailbox , you need to assign the below role to the user and restart exchange shell

Recently when a user tried to look at his Online Archive in Webmail the folder was missing. In Outlook 2016 ( NOT Outlook 2013 as this doesn’t support archive very well ) the folders were listed.

The issue is due to the folder count in Online Archives. The folder limit 10,000 and the current folder count was 15,000

Kindly refer to the below article for more information.

Clearing Cache did not fix this or Zoom size

Reset Chrome to default settings ( which still keeps Favorite bookmarks but clears plugins ) fixed this
