Hello,
We have MS Exchange 2019 on-prem. It is likely that after the installation of CU14 or CU14 Mar24SU, the add-ins installed by default (like My Templates) stopped working.
I have displayed the application configuration
Get-App -OrganizationApp | fl
and I see incorrect URLs in the ManifestXML and IconURL attribute.
The IconURL contains the address:
https://Exchange_FQDN/owa/MailboxGUID@Mailbox_email_domain/prem/15.2.1544.9/ext/def/a216ceed-7791-4635-a752-5a4ac0a5eb93/images/app_icon.png
It seems to me that the URL should be:
https://Exchange_FQDN/owa/prem/15.2.1544.9/ext/def/a216ceed-7791-4635-a752-5a4ac0a5eb93/images/app_icon.png.
The same applies to the SourceLocation attribute in the FormSettings section of the ManifestXML.
The entry looks like this:
<SourceLocation DefaultValue="https://Exchange_FQDN/owa/MailboxGUID%40Mailbox_email_domain/prem/15.2.1544.9/ext/def/a216ceed-7791-4635-a752-5a4ac0a5eb93/page.html" />
and it should look like this:
<SourceLocation DefaultValue="https://Exchange_FQDN/owa/prem/15.2.1544.9/ext/def/a216ceed-7791-4635-a752-5a4ac0a5eb93/page.html" />
Has anyone had this problem and solved it?
Best regards,
Rafal

Hi @Rafał S
Did you upload the add-ins via Exchange admin center?
Have you tried to disable the Exchange Extend Protection to see if it works?
Hi Jimmy,
The problem is with Exchange's built-in add-ins: My Templates, Suggested Meetings, Unsubscribe etc. They all have the wrong configuration. I have not uploaded them via Exchange admin center.
We configured Exchange Extended Protection before installing CU14 and there were no problems with the add-ins. Therefore I don't think the cause is EEP.
Best regards,
Rafal
