this is strange, as the manifest should be in there.
The SweeterSync zip you downloaded from the store is called "SweeterSync_3_0_68_complete.zip". Please, make sure that the zip folder you are trying to upload on the module loader is the one contained within the aforementioned. The folder you need to upload is called "SweeterSync_3_0_68.zip" (without complete in the name).
Let us know if this solves your issue!
have you already put in the SweeterSync configuration the target domain as https://suite.mydomain?
If yes, please try also with http://suite.mydomain.
We'll be also contacting you in private to request some details on the case immediately.
we would suggest looking on the SuiteCRM shop. SuiteCRM official outlook plugin for example should work with mssql. However, that is not server related, but client side.
Hope this helps!
Yes you can use the service without impersonation.
If you can't setup the service based on the manual, we can arrange a teamviewer session. Please contact us in the following email address: firstname.lastname@example.org
