I’m working for a large firm these days and we’ve had a lot of problems with Mac’s Apple Mail for the past few months, internally and with our clients. This has stumped me for a long time but I might have finally cracked the case… at least for us.
The problems are abundant. Sometimes Mail gets stuck in the outbox, other times settings get reset (this is a different issue) and at times the entire program just crashes. When the mail service gets hung up, restarting the computer can often reset it, but isn’t always convenient and doesn’t always work. We just ran into this again this morning and here’s what I did, it fixed the issue instantly.
Go to the menu and click window > Activity
In the activity manager, click the ‘x’ beside the stuck activities. It may take some time for them to cancel. Once they’re clear, go ahead and click send/receive again.
This won’t work for everyone I’m sure, but it certainly worked for us when everything else failed.
I hope this helps someone. Let me know in the comments if this worked for you. Oh, and that other issue I talked about, I’ll post a link to a possible fix for that too.
