Hi, I tried to run start-managedfolderassistant powershell command for a particular user, however I am getting a warning like below Warning: The user "<email address"> archive mailbox is offline. Please let me know how to resolve this warning. I didn't know if this is the reason or not but we weren't able to see auto archive of emails from primary mailbox to archive mailbox. We have assigned the retention policy as 2years archive

Hi @Surya kumar , I didn't know if this is the reason or not but we weren't able to see auto archive of emails from primary mailbox to archive mailbox. Yes, this could be the reason. Please try to run the same command with Exchange GUID instead and see if there would be any difference: Get-Mailbox <UserName> | FL ExchangeGUID Start-ManagedFolderAssistant <ExchangeGUID> In case the issue persist, could you clarify the things below? Have you tried running the start-managedfolderassistant cmdlet against other users and see if the issue can be reproduced? Are you in an Exchange hybrid environment or it's a pure Exchange Online organization? If the answer is helpful, please click "Accept Answer" and kindly upvote it.

In-place archiving must be enabled for the retention policy to work properly. https://docs.microsoft.com/en-us/office365/securitycompliance/set-up-an-archive-and-deletion-policy-... "The first step is to enable the archive mailbox for each user in your organization. A user's archive mailbox has to be enabled so that a retention tag with a "Move to Archive" retention action can move the item after the retention age expires."

Yes, this could be the reason.

Hi @Yuki Sun-MSFT

Like said by you, I executed the command. This time I am not getting the warning. However, I am still not able to see significant difference in the storage of primary mailbox.

As per the mailbox diagnostic logs, I am seeing zero for all the fields such as ELCLastRunArchivedFromRootItemCount, ELCLastRunDeletedFromRootItemCount

We have applied retention policy to the mailbox. Is it possible to check which retention tag was applied to which folder (Inbox, Archive, and other personal folders) of mailbox using PowerShell?? By default, DPT will be applied to all folders unless someone chooses other tags explicitly.

It is not happening to other mailboxes. And all the mailboxes are O365. However, why warning is coming when we execute the command with email address but not with GUID

Hi @Surya kumar ,

Is it possible to check which retention tag was applied to which folder (Inbox, Archive, and other personal folders) of mailbox using PowerShell?

You can run the command below to check the output of ”ArchivePolicy“ and ”DeletePolicy“. Blank on these two columns indicates that folder is set to inherit from its parent folder.

Get-MailboxFolderStatistics -Identity <USERID> | Select Name,FolderPath,ArchivePolicy,DeletePolicy

However, why warning is coming when we execute the command with email address but not with GUID

I tried searching a lot but didn't find official document stating the difference between the two methods. The article below mentions that "When utilizing the GUID we can minimize the change that any initialization process does not cause the command to fail." Not quite clear for me but seems that using GUID could sometimes work when using email address doesn't work.

Hi @Yuki Sun-MSFT

Thanks for the response. I am looking for the logs of managed folder assistant. It should probably be giving when it was run, how many items were processed.

When i run command for diagnostic logs, i am getting last run only. Is it possible to check how many times this was run in a month. And each time, how many items have been processed?

Hi @Surya kumar ,

As far as I know, I am afraid there's no logs available in Exchange online for this.
Have you had a chance to go through the steps in the following article to troubleshoot this issue?

Hi @Yuki Sun-MSFT

I went through the article, however that was giving only the last run. Not giving a complete record which was processed in a month. Can you check this?

And got one doubt while going through the article. Does the archive mailbox inherit DPT's. of retention policy?

Usually MFA process the DPT's for primary mailbox. I am wondering if archive mailbox also inherit then?

DPT's can be delete after 2years, move to archive mailbox after 2 years. Will archive mailbox inherit them? Or emails in archive mailbox lasts indefinitely?

Hi @Surya kumar ,

however that was giving only the last run. Not giving a complete record which was processed in a month. Can you check this?

As indicated earlier, I am afraid it's currently not supported to check all the MRM processing history logs. The reason I mentioned about the article above was just meant to for your reference so that you can follow the other steps to troubleshoot the issue. Regarding the Export-MailboxDiagnosticLogs cmdlet, I checked it on my end and it only giving the last run as well:

Does the archive mailbox inherit DPT's. of retention policy?

Yes. According to the MS official document, "The same policy applies to the user's mailbox and archive."

Default Retention Policy in Exchange Online
Retention policies are applied to mailbox users. The same policy applies to the user's mailbox and archive.

Retention tags and retention policies in Exchange Online

From a retention perspective, the primary mailbox and online archive should not be looked at as separate entities. Retention settings are applied to the primary mailbox, and by design, extend to the online archive. The online archive is an extension of the primary mailbox.
