Office 365 Online-Archive - Not Archiving emails

Question

We have a few users with mailboxes hitting the 50GB quota.
They have a 100GB Archive with roughly 50GB in it.

Most all of the folders are set to 3 Months, 6 Months or 2 Years. I've confirmed this with Powershell.

 Get-MailboxFolderStatistics  -Identity <user> | where {$_.ArchivePolicy} | ft folderpath, ArchivePolicy 

Select allOpen in new window

I've logged the data from the Managed Folder Assistant (MFA), I've issues the  Start-ManagedFolderAssistant for the users and can see that it has run

For one user you can  see she had 79,112 updated, though since the logging is not historical, I cant see if any of the Updated Items were Achieved.

LastProcessed	ItemsDeleted	ItemsArchivedRoot	ItemsArchived	ItemsUpdated
8/7/2021 4:14	0	0	0	79112
8/10/2021 5:53	0	0	0	18

Looking at the size of the Archive and mailbox, nothing is moving out of mailbox into archive.   We can go into folders and see that there are still older messaged than the Archive Policy shows.
 
these users are about at the limit to no longer receive mail. What can we do to get the archive process working correctly for them?

Thanks,

Looks like you may have retention hold placed on those users.

Run this to get a list of users that have the RetentionHoldEnabled set to $true

Get-Mailbox -ResultSize Unlimited  | where {$_.RetentionHoldEnabled}  |Export-CSV "C:\RetentionHoldv1.0.csv" -NoTypeInformation -Encoding UTF8

Then a quick script to loop through and disable retention hold on all and start the MFA again:

$Mbx = Get-Mailbox -RecipientTypeDetails UserMailbox -ResultSize Unlimited | where {$_.RetentionHoldEnabled}
ForEach ($M in $Mbx) {
    Write-Host "Processing" $M.DisplayName
    Set-Mailbox -Identity $M.Alias -RetentionHoldEnabled $false
    Start-ManagedFolderAssistant -Identity $M.Alias 
}

If you need retention hold on other users, then you can run these two commands on the user with the issues:

    Set-Mailbox -Identity <userID> -RetentionHoldEnabled $false
    Start-ManagedFolderAssistant -Identity <userID>

Hi, Henry

According to your description, there's a method for these users which can expand their archive size.

Please ask the O365 Administrator by following the instructions based on the official article - Overview of unlimited archiving and Enable unlimited archiving.

Hope it helps.
