Import-Mailbox ... Still no love.

So as any of you who read this blog know a client of ours has been having Import-Mailbox cmdlet issues. We opened a case with Microsoft only to find out we knew more about the error than the tech assigned to us. Below are the steps that we went through.

PSS Call.

Checked permissions and verified error.

Installed support tools on S6 and added "transition" account to have send-as and receive-as.

replicated information and logged off.

Logged back on and tried again. Same error.

Created new account and granted most of the same rights except for Exchange View only Admin.

Proceeded to test Import-Mailbox cmdlet with the same parameters.

Ran BOTH Import and Export cmdlets and got the same error. PSS asked for more time to research the issue.

Attempted to re-run process with a different user. Result was the same.

Opened ADSIEDIT and manually forced permissions on the config,services,exchange, ORG container.

Logged off and then back on.

Tried an import and then an export GUESS WHAT....SAME Error DUH!

PSS then asked Technician to run Export-Mailbox on the exchange server itself. This again did not work.

Create Test user and try export SAME error.

Mail-Enable new user and try to open OWA.

This process repeated itself a number of times ...all of them resulted in the SAME MAPI error.

But the below manual process works fine. It's just manual and takes forever.

****Able to successfully move mail via profile migration steps:

Add transition user to full access on the mailbox.

Create a new profile for transition that uses migrating user's mailbox.

Open PST and manually DRAG in the old messages.

Contact User and verify that old content has been properly migrated into the Mailbox.

This is a manual process and will take SOME time to complete.

Manual Process is as follows:

For the manual migration process exmerge must take place first. 

To perform this EXmerge.

Use powershell to grant access with Add-MailboxPermission -Identity -User -AccessRights Fullaccess

Create a new outlook profile while logged into your machine with the migration account.

Copy PST file to your local drive.

Open outlook.

Open the PST drag and drop all items from the PST into the Mailbox according to where they go.

Verify with user that process is successful.

Move on to the next mailbox in the list.

Going to speak with the client tomorrow to see if they got resolution.

Talk to you next time,
