Exchange Server 2010 to Exchange Online Message Tracking Does Not Work

My organization is currently working on moving from on premise Exchange to hosted Exchange from Microsoft via Office 365 and Exchange Online.

Prior to moving any mailboxes to our tenant, we have been testing from on premise mailboxes to test cloud mailboxes.  

We were tracking messages from Outlook Web Access.  Under Manage My Organization, Mail Control, we'd run Delivery Reports.

I would search from an on premise mailbox to a cloud mailbox for messages I had sent.  The search would work well and return results.






 













Once I double clicked one of the results to see detail, however, that wasn't successful.  It would not be successful and would fail after a timeout.

 








I opened a ticket with Microsoft Support.

It wound up being fairly involved and we did quite a bit for troubleshooting.  But the ultimate solution was to close the ticket as a known bug.

I consulted about the results of our last troubleshooting to get Message tracking report using EMS and we got the error related to “WARNING: The log search service was unavailable on server 'mwhpr09mb2047.namprd09.prod.outlook.com'.”

It’s a known issue on O365 which possibly might not be addressed any time soon, the alternate option would is to use the Messaging Tracing if they can in our  scenario. Message Tracing is available to admins only, can't directly search on Subject (but can search on recipient, sender, date/time then sort to locate specific subject).

As an administrator, you can find out what happened to an email message by running a message trace in the Exchange admin center (EAC). After running the message trace, you can view the results in a list, and then view the details about a specific message. Message trace data is available for the past 90 days. If a message is more than 7 days old, the results can only be viewed in a downloadable .CSV file.

Since this a known issue in product, you will not be charged for the incident. 

So, I can track messages from the Office 365 administrator center, and can do nothing to correct the issue impacting my on premise message tracking

How To Map A Network Drive to OneDrive for Business (or What To Do If You Don't Have Enough Free Space to Sync Your OneDrive for Business Data)

My organization is currently in the early stages of looking a migration to Office 365.  I welcome the possibility of getting out of the business of managing users' home folders by giving them 1TB of cloud space on OneDrive for Business and letting them use it as they see fit.

We are currently in the process of deploying SSD drives to some of our computers to help with performance issues.  As a cost savings measure, I know we are often deploying 120GB drives.  As we test and evaluate, several colleagues asked me what would happen if we had more data than we had hard drive space.  I would assume that a 120GB drive might have 80GB free after the installation of operating system and software. It's very possible that some of my users have more data than that.

I opened a support ticket with Microsoft and got a great option.  They confirmed that the OneDrive sync client might crash or slow the system down if it was trying to sync more data than space allowed.  There are options to not sync down the entire OneDrive contents, but I worried that might be cumbersome for users.  

The alternative is to skip the OneDrive sync client and map a network drive to the OneDrive for Business space.  This means you need Internet access to access your data, and there could be bandwith implications, but this sounds like a great option.

The steps to do this are as follows (as demonstrated on Windows 10):

• Open Internet Explorer
• Go to https://portal.microsoft.com. Keep me Signed In option box checked and Sign In 
• Depending on your version of Internet Explorer, take one of the following actions: 
• Click the Tools menu, and then click Internet options. 
• Click the gear icon, and then click Internet options.
• Click the Security tab, click Trusted sites, and then click Sites
• In the Add this website to the zone box https://*.sharepoint.com >add> ok 
• Click on Custom level> Scroll all the way down to select Automatic logon with Current username and Password.
• Browsed to   gear icon on IE >compatibility view settings > sharepoint.com> ok
• Start > Run > type Services.msc > Search Web Client >Change Startup to Automatic > Ok
• Browsed to the OneDrive Location which you want to map  > Click on return to Classic OneDrive >click on Gear icon >Ribbon On >click on Library >Open with Explorer>>and copy the  path 
• Open File Explorer>right click on This PC or My Computer> Map Network Drive> Select the drive and paste the URL> ok
