Dynamics, Teams, Exchange, Active Directory all suck. There are better alternatives but CIOs are stuck in 1996. Apple themselves in their corporate IT environment use none of those things yet somehow are one of the biggest and most profitable companies in the world. Azure is garbage compared to AWS. Using Azure Blob vs S3 is a nightmare. MSSQL is garbage compared to PostgreSQL. Slack is vastly better than Teams in literally every aspect. I just did a project moving a company from AWS to Azure and it was simply atrocious. Nobody at the user level likes using MS products if they have experience using non-MS products. It’s like Bitbucket — nobody uses that by choice.
