hi 

I clicked on the "Authorize" button and validate the process successfully. and saved the settings, but when try to click on the "test connection" button the below error appear: 

"The test email failed because: Failed to connect to the email server outlook.office365.com:993. This issue can occur if the server does not support IMAP. [LFF2002-EmailApprovalServerConnection]"

is there any solution for this issue ? 

Hi, can you specify the version of Form you are using? As we have fixed a similar bug with ID [389261] in 11update3. So, we recommend you update your Form if you are using a lower version. 

Besides, you can check the configuration of your Microsoft 365 account for SMTP OAuth 2.0 by the following steps:

1. Login into admin center
2. Find and click your account under Users >> Active users
3. Under Mail >> manage email apps, make sure that "IMAP"  and Authenticated SMTP are enabled. 

If the issue still occurs after you tried above steps, you can propose a support case.

Hi, we now support masked client secret value when focus out in Configuration site on Forms 11 Update 4.

You can see other changes from:

Get Forms 11 Update 4 from Laserfiche 11 package:

Software versions and fixes included in the Laserfiche 11 Download Package - Knowledge Base

Authorization succeeds, and then the config is saved, but testing fails as it does for the Shaban user above.

Is this issue still not rectifiable in Forms version 10.4.5.xxx? We can upgrade to Forms 11 update 5 if that's what's needed.
