Fixing the Message store has reached its maximum size Outlook 365 home

April 8, 2020 10:27 AM

I'm extremely frustrated not finding a solution to my outlook issue. I have tried all kinds of things. I have removed tons of emails (naturally, I can't remove them in my outlook but I can do it in my gmail account). I have allowed archiving. I have previously managed to get out of this using these tricks but not this time. I have some info that I really need in my contacts folder....

I'm scared about tinkering in regedit. However, the 4 register entries are (and I think they spell trouble):
(Default), Reg_SZ, (value not set)
EnableMarch2018BestBodyFix, REG_DWORD (0x00000000 (0)
EnableNewCorruptionUx, REG_DWORD (0x00000000 (1)
LastCorruptStore, REG_SZ (C:\Users etc

How would I proceed safely and preferable not losing what I have in my contact.

This advice is ONLY if you're using Outlook as a local client to data that is fundamentally stored elsewhere (e.g., Google mail, contacts and calendars).

How much data is stored ONLY in your local Outlook?

If it's all sync'd from Gmail, then you might try just deleting the whole account locally and then re-adding it after you've done some pruning in the Gmail interface.

Response by poster: Thank you so much!
I was thinking that that might be my only course of action.

I have all my passwords stored in my outlook contacts and am desperate to get access to them. Can you think of a way at this point? Those exist only locally and not in my gmail.

I really don't, since the issue is entirely theoretical to me -- I've never had a "local storage max" problem with Outlook.

Does it fail to open entirely, or just happen when it tries to talk to the server?
