EXCHANGE – X-OWA-Error: Microsoft.Exchange.Data.Storage.StorageTransientException


New day, new problem !

Some users for an unknown were not able to connect to OWA and Outlook suddenly, I never had time to find why unfortunately…

The error in OWA was : X-OWA-Error: Microsoft.Exchange.Data.Storage.StorageTransientExceptiontransienterrorexchange2013

What I did to correct the issue was simply to modify one digit  of the legacyExchangeDN, the last part which is random.

Hop this will save time in case it happens to you



O365 – Create Mail User from AADConnect synced user

Hello all,
A few days ago, I had to make a user in a local AD appearing as a contact in O365 address book.
The local AD was not having a local Exchange so I couldn’t use the ECP to populate the right attribute…
Here are the required attribute to fill in the local AD user to make it appear in O365 address book as a contact (mail user):
mail =
mailNickName = internal.username (should be the same value as samAccountName)
targetAddress =
proxyAddresses =
Hope this will save time to you
