Search for Workaround - failing Outlook activities (Win11, new Outlook version)

Dear Forum :slight_smile:

the new year started with a unhappy surprise. We upgraded some of our environments to Win11 and realised then, that Outlook isnt working anymore.
For reference please check that article.

Therefore we arent able to use
Get Outlook Mail Message
Send Outlook Mail Message
anymore
There is no particular exception beside some HRESULT one for sending. For receiving we just get null values as return (Like sender, body & attachments) - interestingly the subject is readable.

Since most of our processes use Outlook at some point I need a workaround asap.
For using IMAP and SMTP the IT have doubts and dont really want to give us access.
In case you have good points to mention, that its basically save and worth to give access please just shoot some over.

Or developing over the UI, but honestly with the amounts of mails I`m not sure how to build it properly and stable.

Do you guys have other clever ideas to solve that issue. I believe we cant be the only ones.
Unfortunately Office365 isnt introduced soon due to security concerns :confused:

Thanks a lot for you help and happy new year

Hi there,

it would help if you state what goes wrong. Stating ‘it doesn’t work’ gives us little to work with.

  • What activities do you use
  • Do you have a code example
  • Error messages if any
  • Version of the mail packages/dependencies
  • some coffee would be nice

Unfortunately, this is the only option you have if you have to use Outlook activities.

Check if you can toggle off the Try New Outlook button to use classic Outlook.

Ui automation won’t be reliable so avoid it.

This is the best option you have if you can get it enabled from your IT team.

@ashokkarale Thanks for your reply, i was afraid of that :confused:

Unfortunately I dont have the toogle to switch back to classic Outlook. Just checked online and within the application.
Then the last hope is to get SMTP & IMAP access but due to security thats going to be a tough one.

For now you can go with classic toggle on outlook

but soon you need to migrate to O365 as 2027 is end for classic support

cheers

@Anil_G Yes I hope we can do it but I cant see that toggle option in my outlook.
Can they disable it / are there other ways (I also cant see the registry entry) to re-enable the classic one?

@FreddyW

Here you have the troubleshoot steps if you dont find toggle

cheers
