What about Office Suites?
I guess most still wonder if they can/should use Office365, G Suite and similar to process EU citizens personal data.
The short answer is: No, you are violating data subjects fundamental right to Privacy (art. 7 and 8) as stated by the EUCJ.
You could do it if you obtain informed consent from the users, as their personal data will be often shared in Azure AD, and the people you are writing about/contacting by email/adding to your CRM/etc...(data subjects) stating clearly that their personal data will be transferred to a data importer (Microsoft/Google/etc) which, regardless if the contract is signed with a EU subsidiary and stored in EU, cannot ensure an adequate and equivalent level of protection and by doing so it will violate their right to privacy (and contribute to support the expansion of surveillance capitalism business models but that's another issue).

These transfers fall under the Use Case 6 of the EDPB recommendations as the text you are writing in Word or the emails you are sending out are all processed in clear so at present you are not able to use those tools without violating people's privacy and naturally that will make your organisation also non GDPR/DPA compliant.
