Exchange Account Keeps Deleting

[AFPBoy]

Til this day....and going

I just wanted to add a "me too" post. I also deleted one entry in my Contacts list, and that's preventing my Exchange account from being deleted (so far 6 hours versus 30 minutes). I'm keeping my fingers crossed.

Hey! Been fiddling with this. I have 2 exchange accounts that kept disappearing moments after adding them, and only my Exchange accounts (iCloud, Gmail, non-specific IMAP all remained). Tried restarting, deleting the V6 folders in the user Library, and reinstalling macOS Mojave. None worked. I then turned to Keychain Access after reading some success elsewhere on the Apple forums. Here is what I did and it has worked since. (Attaching screenshot of Keychain Access as well)

• Open Keychain Access (spotlight search is fastest)
• On the left-hand side, chose All Items
• In the Keychain Access search bar in the upper right, search for exchange
• In the results below, select all items that have com.apple.account.Exchange.oath-### and Delete them
• Quit Keychain Access and go Preferences --> Internet Accounts and re-add the Exchange accounts

This has worked for me, and all 100,000+ emails have re-synced without the account vanishing. Hope it works for you!

This worked for me to fix this problem. Thank you for the assistance.

For those that continue to get this problem (such as myself!) there's a very encouraging entry in the release notes for MacOS 10.14.4 which was released yesterday:

I'm going to install the update now, but seeing the problem specifically mentioned in the release notes is VERY encouraging!
