Hi Everyone,
Sorry for the inconvenience caused by this issue.
I'd like to share some workarounds with you.
Workaround 1: Please save the file on local and use Insert > Attach fileto locate the file and put it in your email.
Workaround 2:
Turn off MAPI over HTTPs by setting the registry key MapiHttpDisabled.
Key: HKEY_CURRENT_USER\Software\Microsoft\Exchange
Value: MapiHttpDisabled
Type: REG_DWORD
Data: 1
Workaround 3:
Turn off the configuration of the E-mail Settings for Microsoft Exchange.
Delete all Profiles. This can be done by using the Control Panel option Mail or deleting the following information in het registry.
Key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook
Value: DefaultProfile
Type: REG_SZ
Data: Profile name
And delete all registry keys under this key. So don't delete key itself.
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Profiles
Delete the following registry value to enable First Run again.
Key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\16.0\Outlook\Setup
Value: First-Run
Type: REG_BINARY
Data: <binary data>
Add the following registry value to enable the automatic configuration of Microsoft Outlook.
Key: HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\AutoDiscover
Value: ZeroConfigExchange
Type: REG_DWORD
Data: 1
This behavior is triggered by a known issue that occurs when Outlook is connected to an Exchange Server 2013 mailbox through a MAPI over HTTP connection. To determine whether
you are using a MAPI over HTTP connection, follow these steps:
- With Outlook running, press the CTRL key and right-click the Outlook icon on the taskbar.
- Click Connection Status.
- View the Proxy Server, Server name and Protocol columns.
- If you are using a MAPI over HTTP connection, the Proxy Server column is empty, the Server name column lists the actual server name, and Protocol column displays HTTP.
Note If you are using an RPC over HTTP connection (Outlook Anywhere), the Proxy Server column contains the server name, the Server name column lists the GUID of the server, and the Protocol column displays RPC/HTTP.
For more information about MAPI over HTTP connections, go to the following Microsoft TechNet website:
