Yosemite 10.10.5 Mail problem is worse now

I logged out of iCloud and logged back in and it fixed the issue. I was very lucky not to have to resort to the more complicated solutions on this thread.

Further to my last post in reply and thanks to GAMacGuy,

Your solution DID fix my issue BUT I found it easier to go through each IMAP account, delete it and then set it up again. Not all of my accounts were corrupted, just a few but it would always seem to be a new one here and there each time I opened and used Mail so I just removed all IMAP accounts that were not fresh setups (in the last few days) and then set them up again. No more issues.

I have a heap of accounts so it was a bit time consuming BUT better than trying to chase around a fault when I'm not a programmer. Still quicker for me to do this and setup all of my custom email addresses again than chase an unknown fault.

NOTE: I found I didn't have to do it with the couple of POP accounts I still have but if I had to do them too I would make sure they were backed up BEFORE deleting and then setting them up again.

Once again thank you GAMacGuy

PS - I'm not an expert, just making an observation: It seems that after this upgrade 10.10.4 to 10.10.5 the Internet Accounts pane loses some or most of the Google passwords and webmail passwords.

I've had the same problem after upgrading to 10.10.5. Logging out of iCloud helped, but only for a little while. Now when Mail hangs the system, I force a shutdown and restart my Macbook Pro. This does the trick for a little while as my Mail program is working as expected. I suspect there are issues in the upgrade and hopefully these will disappear with then next operating system. For now I'm just following the route of shutting down the system and then powering up again.

Hi Linc Davis
