Since I need some email from an address I use, I figured I’d have some fun and spin up the ol’ Exchange server.<\/p>\n

To my surprise when I attempted to login to OWA (since the front ends were loading just fine) after authentication I would be greeted with “Microsoft.Exchange.Data.Storage.MailboxOfflineException”.<\/p>\n

My initial googlings didn’t provide much of good results.<\/p>\n

I went to the server and did the usual check services and such, and noticed the root cause. Low Disk Space. I figured extending the logical volume and a reboot would suffice… nope. Problem persisted.<\/p>\n

I decided to run the MS Exchange health checker: https:\/\/aka.ms\/ExchangeHealthChecker<\/a><\/p>\n

even after getting everything green in the health checker, the problem persisted.<\/p>\n

A bit more google fooing and I was able to track down someone with a similar problem on TechNet<\/a> with some useful guidance to use eseutil.exe to check the database.<\/p>\n

The database indeed return “Dirty Shutdown”<\/p>\n

\"\"<\/a><\/p>\n

ran the repair commands. *Note* you should try to use \/r before using \/p if it works you don’t need to use \/p as it’s a hard recovery and data loss could ensure from it. I didn’t care as it’s use lab data.<\/p>\n

\"\"<\/a><\/p>\n

K checking again it return “Clean Shutdown” everything I’ve read says it should be able to be mounted now. Failed to Mount….<\/p>\n

\"\"<\/a><\/p>\n

As a last ditch effort, I try to Google some more if I missed something else. I found this nice post by Eric Simson<\/a><\/p>\n

Step 1: Backup the Database (my case don’t care)
\nStep 2: Check Storage
\n(Was the cause, extended volume to 190GB used out of 250GB)
\nStep 3: Restart Exchange Services (Yeap, ran health checker)
\nStep 4: Check Database State (Yeap fixed it)
\nStep 5: Repair Exchange Database (Yeap fixed it)<\/p>\n

Yet even after reboot and using PowerShell AND using accept data loss…<\/p>\n

\"\"<\/a><\/p>\n

I was about to give up when I had one final idea, I realized that since \/p does a hard recovery of the DB even if the log files are lost, and the log files take up a lot of space…<\/p>\n

\"\"<\/a><\/p>\n

At this point I had well over 50% free space on the server. I ran the repair DB command again just to be safe.<\/p>\n

\"\"<\/a><\/p>\n

wait.. what .. no error…. guess I was only at 24% free space, and that wouldn’t cut it, I don’t get why considering the -AcceptDataloss was defined.<\/p>\n

Go to log in to OWA…. Ehhhh!!! There’s my emails!<\/p>\n

Hope this helps someone.<\/p>\n","protected":false},"excerpt":{"rendered":"
