I had a similar issue with Gmail last year. It was slowing down just when I had to send out urgent work emails. It definitely made me realize how essential it is to have a backup plan or alternatives ready.
microsoft has better flexibility. you can have shared mailboxes for free on microsoft, but on google, you gotta pay for a mailbox regardless... daz madness lol
For anything email-related, I’ve started using aged Gmail accounts for some projects. They tend to work smoothly and are reliable, especially for things like marketing or maintaining credibility in communication.
