I've recently updated from macOS 10.15 to Big Sur.
Generally everything works, apart from the search tool in macOS's native Mail.app: when I try to search for an email, phrase, contact etc, half the time i get 0 results, or the search query does not impact the results eg nothing changes / is search for.
Ive got multiple email accounts setup in mac mail. Some gmail, some google apps for business, some IMAP provided by 3rd party web host.
The accounts / mailboxes range in size from c. 1GB - 20GB and there is one large mailbox of c. 90GB
The problem is most pronounced on the gmail / google apps for business accounts.
This never used to happen on 10.15 (or other previous versions of Mac OS / OSX for that matter)
What i have tried to date :
- rebuilding the accounts as per user Jaume's suggestion
- deleting the accounts and re-adding them
In both instances this helped seemed little a first, but after a while the issue was back to where it was before. If i was to speculate i would say its almost as if the issue is caused by one of the following :
mac mail not caching the emails so when you search its running a full search of the mail server
mac mail not indexing the emails correctly
