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.

Recently when trying to access a users Office 365 Unlimited Archive Mailbox using Outlook 2013 I was shown the error “Cannot display the folder”
Outlook 2013 is actually not supported for Office 365 Archive , you will need to install Outlook 2016 for this to work and it will show the emails
Below is the command to extract ( Archive ) emails from a particular folder into a PST
#Archive Items from a certain folder
New-MailboxExportRequest -mailbox %mailboxname% -IncludeFolders "path/to/folder/ -ContentFilter {(Received -lt '08/01/2014')} -FilePath \\path\to\pstfile.pstHowever due to Exchange updates , the MailboxExport command does not work anymore ( which had the -deletecontent command) and Search-Mailbox does not have any functionality to Include just specific folders. So we have to use powershell EWS below
Note – By default ItemView has a limit of 1000 in exchange, the command below you will probably want to increase this say to 10,000 or even 50,000 so you don’t have to rerun this lots of times. After each run it will tell you how many items it has deleleted. You need to run the powershell script with a useraccount that has a throttling policy set above 1000.
e.g. Set-ThrottlingPolicy PolicyName -EWSFindCountLimit 50000
Set-Mailbox useraccount -ThrottlingPolicy PolicyName
