Exchange 2013 Error code -2146233088 – Exceeded Maximum Number Of Large Items

If you have a PST file with a large amount of emails in it and you want to import the PST into Exchange 2013 then you will use the New-MailboxImportRequest  Normally the only problems you can get with this is if there are corrupted emails in your mailbox. In Exchange 2013 their is an additional option for LargeItemLimit, this needs specifying how many large items you would like to ignore the size of and import them, Exchange 2013 will only let you ignore a maximum of 50 “large” emails before it will fail again without the additional AcceptLargeDataLoss” where you can specify that its  OK to move the mail between mailboxes and anything over 50 large emails will be ignored. If you do not specify these commands you get the Error code -2146233088. You can specify what is a large email with the set-transportconfig command.

Below I will show you how use this command in powershell.

Exchange 2013 Specify LargeItemLimit In Powershell

First the command then the explanation.

New-MailboxImportRequest -Mailbox Allen -FilePath \\techieshelp\PSTFiles\allen\Allen.pst

In the command above the -Mailbox “Allen”  is the Exchange 2013 mailbox we are importing to and the -Filepath is the location of Allen`s PST. We do not specify a folder so all emails and folders are imported into the root of Allen.

If we wanted to restore these emails to a specified folder then we would add the -TargetRootFolder “RestoredPST” flag, where RestoredPST is a folder in allen. If the PST file had Large emails attachments we would use the command below

New-MailboxImportRequest -Mailbox Allen -LargeItemLimit 50 -FilePath \\techieshelp\PSTFiles\allen\Allen.pst

The LargeItemLimit 50 allows 50 “large” emails to be skipped before the import is marked as failed, if there are more we need to issue the AcceptLargeDataLoss command as below to allow the import to be successful,

New-MailboxImportRequest -Mailbox Allen -LargeItemLimit 50 -AcceptLargeDataLoss -FilePath \\techieshelp\PSTFiles\allen\Allen.pst

This will drop all “large” emails after it has imported 50.

    If you read http://technet.microsoft.com/en-us/library/ff607310(v=exchg.150).aspx, you’ll see that the import will skip the large items and NOT import them, and mark the import as successful.

    If you set a number using LargeItemsLimit, it will skip this many items before designating the import a fail.

    I thought the same as you, i.e. that it will import them anyway, but it actually skips them. This works similar to the baditemslimit.
