Encrypted email throws no license error - even when logged into OWA in another tab

M4RM 0

I get a License exception in OWA, When opening a Microsoft encrypted email in outlook desktop, when it opens the message in OWA for security.

I have verified/corrected outlook desktop and edge are logged into the correct/same Microsoft account, I already have another tab in edge (same when in chrome browser) logged into the correct/same OWA account. I also cleared edge's cache, rebooted, etc.

I get the following license error in edge: "Microsoft.Exchange.Clients.Owa2.Server.Core.OwaUserHasNoMailboxAndNoLicenseAssignedException"

The user has separate Microsoft accounts for 365 and mail which is where I believe where the issue lies.

Outlook desktop, edge and OWA are logged into the same account for mail. but Outlook and edge were logged into the incorrect account when the email was downloaded.
Outlook still shows 2 Microsoft accounts under office account , but is logged into the correct mail/outlook account

I can log into OWA, and open the encrypted email without issue, the issue is only using outlook desktop to open the encrypted message, which in turns tries to open the message in OWA, and the license exception.

1.) I updated Outlook (office) - saw no change - still throwing no license error in owa

2.) I made a test Profile - saw no change - still throwing no license error in owa

Any thoughts on how to fix this?

I am fairly confident outlook is trying to open the message under the wrong account, the one that does not have an exchange account associated with it.

Hi @M4RM ,

Welcome to our forum!> Outlook desktop, edge and OWA are logged into the same account for mail. but Outlook and edge were logged into the incorrect account when the email was downloaded.

I made a test Profile - saw no change - still throwing no license error in owa

What do you mean about "but Outlook and edge were logged into the incorrect account when the email was downloaded"? And do you mean that you create a new Outlook profile and try to open the email, but the error shows in OWA?

Hi ChristyZhang-MSFT,

Your assumption is not quite right, let me elaborate:

The user has two 365 accounts, one for full 365 with no exchange, and another exchange account with outlook.

365 account

exchange account w/outlook license

The Outlook desktop was logged into the Microsoft account for the 365 (without exchange), while the profile was using the email account with exchange. User opens the encrypted email in Outlook desktop, outlook does some type of autentications, and creates a OWA link, click on the the link, and edge opens to an OWA error "OwaUserHasNoMailboxAndNoLicenseAssignedException".

I opened OWA in edge in another tab, tried again, and received the same error.

I changed the 365 account in Outlook desktop to use the account with exchange, for both email and 365 account credentials, opened the email, Outlook desktop did its authentication, I clicked on the link, again "OwaUserHasNoMailboxAndNoLicenseAssignedException" error opening OWA.

Edge was the browser used to open OWA, so I made sure this was also logged into the same exchange account as the email.

I opened the email in outlook desktop, Outlook desktop did its authentication, I clicked on the link, again "OwaUserHasNoMailboxAndNoLicenseAssignedException" error opening OWA.

I changed the default browser to Chrome, I opened the email in outlook desktop, Outlook desktop did its authentication, I clicked on the link, again OwaUserHasNoMailboxAndNoLicenseAssignedException" error opening OWA.

I did the same as above, but opened another tab in chrome and connected it to OWA, I opened the email in outlook desktop, Outlook desktop did its authentication, I clicked on the link, again OwaUserHasNoMailboxAndNoLicenseAssignedException" error opening OWA.

=-=-=-

As for the profile, I created another "duplicate" profile with the same exchange credentials to ensure there was no profile corruption causing this. The results were the same with the new profile "OwaUserHasNoMailboxAndNoLicenseAssignedException" error

Notes:

I can open the default browser to OWA, and log in without issue, and can browse and open the encrypted email without issue. This would be a workaround, as the user uses the desktop Outlook primarily, and having to open OWA just for encrypted email is not acceptable.

Other users on the same encrypted email thread have no issues, they open the email in outlook desktop, it authenticates, and creates the OWA link, click on the link, and OWA opens flawlessly.

Please let me know if you need additional clarification, this has ne stumped.

Quick repair was the fix!

I completed a quick repair on 365.

I opened the encrypted email in Outlook Desktop, it did its rights management and provided the OWA link, which I clicked.

When Edge opened, it prompted for which account I wanted to use to open OWA.

I chose wisely, and the the message opened successfully!

The repair must have gotten rid of the hook the other/incorrect 365 license had into OWA/edge
