Hi Team,

I got the above error when i use update version of Mail activity(UIPath.Mail.Activities).
The workaround is only to downgrade the version?

Hello

from what Mail package version have you updated?
The Exchange Server is using TLS 1.0 ?

Hello @RajeshT ,

TLS 1.0 and TLS 1.1 were deprecated by Microsoft and many other Software providers will soon follow. More details here Disabling TLS 1.0 and 1.1 in Microsoft 365 GCC High and DoD - Microsoft Purview (compliance) | Microsoft Learn
We added TLS 1.2 support in 20.4 and removed support for TLS 1.0 and 1.1. Most likely, your server has not been upgraded yet, hence, the problem.

Hi @studioX @Corneliu_Niculite,

Is there is any work around,if i am using Studio 20.4 version with TLS 1.0/1.1 still can send messages.

TLS 1.2 not upgraded from our end not sure they dont have any information about this.

I am just worrying if my older version of UiPath Studio will upgrade it wont work for me.

Hi @donghai,

I find only that solution as of now,the current version of community version doesnt support exchange server if the TLS 1.2 not activated.

hello @RajeshT. We have been doing a series of developments for the Exchange activities. Would you like to try the latest package and tell us if it works? You might need to change how the activity is set up though.
