Hello,

Plan1:

Make sure the Organization storage, Archiving storage, Recovery storage etc all match.
So you will need to compare the Hosting plan vs Mailbox plan vs Resources available.

Once you compared the 3 you should be able to find which value is not set correctly.

Please note Recovery items should be 6144 or higher (not 0 or unlimited) even tho you do not have litigation hold enabled (in general i would never enable litigation hold).

Plan2:

Connecting to remote server ibtcloud-mail failed with the following error message : Access is denied. For more information, see the about_Remote_Troubleshooting Help topic. at

Always means there's an issue with the auth.
It's a relatively easy fix tho:
1) SolidCP Portal settings:

• Check the Hosted Exchange provider, make sure the powershell url is https and it's set to the internal fqdn of the CAS (so for example   https://mail1.mylocaldomain.com/powershell ) if it's set to an external fqdn it will require additional permissions.
• In the configuration --> servers --> [servername] page check:  Active Directory settings --> set auth to none, make sure the AD root domain is filled in, login and password should be left empty.
• In IIS of the Exchange CAS which has SolidCP Server installed --> Make sure it's an Active Directory user, and that the user is member of organization management, domain admins, and enterprise admins. (if any perms are changed/ added make sure you do a iisreset to pick up the changes).

2) Exchange Powershell settings:

• Go to ECP --> Servers --> Virtual Directories --> Powershell.  Make sure the url is HTTPS (not http) then go to the security tab --> make sure Integrated auth is enabled. On any changes it would be recommended to do an iisreset.

Once their all set correctly it should give no access denied errors.

Marco

Dear Marco,

Thanks for your reply.

All the settings advised by you were verified, however no luck.

I uninstalled everything and carefully completed the configuration from start.

Now i have a new error when i try to create a user / mailbox.

Error creating mailbox. See audit log for more details.
